This regulatory document is part of the CNSC’s financial guarantees series of regulatory documents. . The full list of regulatory document series is included at the end of this document and can also be found on the CNSC’s website.
Regulatory document REGDOC-3.3.1, Financial Guarantees for Decommissioning of Nuclear Facilities and Termination of Licensed Activities, sets out requirements and guidance for applicants and licensees regarding the establishment and maintenance of funding for the decommissioning of facilities and termination of activities licensed by the Canadian Nuclear Safety Commission.
REGDOC-3.3.1 provides information on financial guarantees used to ensure a licensee will have sufficient funds to decommission a licensed location and dispose of any associated nuclear substances. The document is intended to form part of the licensing basis for a regulated facility or activity within the scope of the document. It is intended for inclusion in licences as either part of the conditions and safety and control measures in a licence, or as part of the safety and control measures to be described in a licence application and the documents needed to support that application.
This document supersedes G-206, Financial Guarantees for the Decommissioning of Licensed Activities, published in June 2000.For information on the implementation of regulatory documents in the licensing basis and on the graded approach, see REGDOC-3.5.3, Regulatory Fundamentals.
The words “shall” and “must” are used to express requirements to be satisfied by the licensee or licence applicant. “Should” is used to express guidance or that which is advised. “May” is used to express an option or that which is advised or permissible within the limits of this regulatory document. “Can” is used to express possibility or capability.
Nothing contained in this document is to be construed as relieving any licensee from any other pertinent requirements. It is the licensee’s responsibility to identify and comply with all applicable regulations and licence conditions.
The Nuclear Safety and Control Act (NSCA) authorizes the Commission to require financial guarantees that it considers necessary for the purposes of the Act.
Applicants and licensees are required to make adequate provision for the safe decommissioning of existing or proposed nuclear facilities by ensuring that sufficient financial resources are available to fund all approved decommissioning activities should the licensee is not be able to fulfill its obligations. Operationally, the Commission may also require financial resources be available for termination of licensed activities other than for decommissioning of nuclear facilities.
This document provides requirements and guidance to applicants and licensees regarding the establishment and maintenance of funding for the decommissioning of facilities and termination of activities licensed by the Canadian Nuclear Safety Commission (CNSC).
This document presents information for those who have incurred, or expect to incur, obligations with respect to the decommissioning of nuclear facilities or the termination of activities licensed by the CNSC.
Part I of this document pertains to financial guarantees for decommissioning of nuclear facilities or activities authorized under Class IA and B, uranium mines and mills and waste nuclear substances licences.
Part II of this document pertains to financial guarantees for the termination of licensed activities, such as for nuclear substances and radiation devices, prescribed equipment, and Class II facilities.
1.3 Relevant legislation
The provisions of the Nuclear Safety and Control Act and regulations that are relevant to this regulatory document include:
The CNSC’s mandate is to regulate the use of nuclear energy and materials to protect health, safety, security and the environment; to implement Canada’s international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public.
The CNSC defines decommissioning as the administrative and technical decommissioning actions taken to allow the removal of some or all of the regulatory controls from a facility or location where nuclear substances are managed, possessed or stored. Decommissioning actions are the procedures, processes and work activities that lead to the release of a facility or location from regulatory control, with or without restrictions on its future use (for example, decontamination and/or dismantling of structures, systems and components).
Financial guarantees are a tangible commitment by a licence applicant or a licensee that there will be sufficient resources to safely terminate licensed activities. A financial guarantee does not relieve licensees from complying with regulatory requirements for decommissioning of nuclear facilities or termination of licensed activities – the financial guarantee ensures that there are funds available to the CNSC when licensees are unable to carry out safe decommissioning or termination of activities.
Sustainable assurance of safety is guided by the two key principles of decommissioning: “the polluter pays” and “the intergenerational equity” principles. These principles raise specific financial obligations for decommissioning. These financial obligations are intended to ensure:
- funding is available to make adequate provisions for the health and safety of current and future generations
- the applicants and licensees establish adequate funds to pay for the decommissioning and termination of their licensed activities
Financial guarantees must be sufficient to cover the cost of decommissioning of nuclear facilities or termination of licensed activities authorized by the current licence.
The types of instruments for financial guarantees can vary. The applicants and the licensees should select an instrument that suits the scope and the timeframe of their decommissioning plan.
The requirements and guidance for decommissioning planning are provided in draft REGDOC‑2.11.2, Decommissioning and CSA standard N294-09, Decommissioning of Facilities Containing Nuclear Substances .
3. Acceptance Criteria for Financial Guarantees
The Commission, or where a licence is used by a designated officer, the designated officer will determine the acceptability of any proposed financial guarantee. The following are the CNSC’s general expectations for criteria of liquidity, certainty of value, adequacy of value and continuity. A licensee may propose alternatives approaches to meet the intent of the acceptance criteria for financial guarantees.
The proposed financial guarantee must be such that the instrument can be drawn upon only with the prior acceptance of the CNSC, and such that payout for decommissioning purposes is not prevented, unduly delayed, or compromised for any reason.
3.2 Certainty of value
Licensees must select funding or security instruments or arrangements which provide full assurance of their value.
3.3 Adequacy of value
The value of the financial guarantees for nuclear facilities must be linked to the cost estimate associated with the most up to date decommissioning plan.
Financial guarantees for other licensed activity must be linked to their licence.
The required financial guarantees for decommissioning and termination of licenced activities must be maintained on a continuing basis. This may require periodic renewals, revisions or replacements of securities provided or issued for fixed terms. In order to ensure continuity of coverage, financial guarantees must include provisions for advance notice of termination or intent to not renew. See section 5 for additional information.
4. Acceptable Financial Guarantee Instruments
The following sections provide examples of acceptable financial guarantee instruments. In all cases the financial guarantees instruments are subject to financial and legal review by CNSC staff and must be accepted by the Commission or where a licence is used by a designated officer, the designated officer.
4.1 Cash funds
Cash funds include cash as well as other equivalent securities such as certified cheques, bearer bonds and guaranteed investment certificates.
These instruments can provide certainty and adequacy of value, ease of liquidity, and continuity. Such instruments provide maximum protection against the risk of default.
Any cash collateral or direct funding should be made into an account which is controlled by the federal government (either the CNSC or the Receiver General for Canada) or by a Canadian chartered bank listed in Schedule I or II of the Bank Act.
4.2 Investment funds
Investment funds are financial instruments that are publicly traded or can be easily liquidated if required.
Funds earmarked for financial guarantees purposes may be invested in an investment portfolio in order to earn interest income to help to cover the costs of decommissioning.
When investment funds are used, there are several economic estimates that must be made including the rate of inflation over time, and the estimated rate of return of the portfolio. Information on planned disbursements should be included in order for the CNSC to review the financial guarantee to ensure it is sufficient to cover costs of decommissioning.
4.3 Letters of credit
A letter of credit is an agreement between a licensee and a financial institution.
A letter of credit can provide for specific sums of money to be paid on demand to designated parties or their agents should a triggering event occur, such as a licensee defaulting on its obligation to decommission. Letters of credit can provide certainty of value, may be easily liquidated, and may be rewritten or revised as the required amount of security changes. Appendix A provides an example of a letter of credit.
Acceptable letters of credit should be issued by a Canadian chartered bank listed in Schedule I or II of the Bank Act.
4.4 Surety bonds
Surety bonds include bid bonds, performance bonds, labour and material payment bonds and maintenance bonds. Surety bonds are widely used in the construction industry.
Variations of these bond types may be appropriate as primary security, or to complement other guarantees.
For example, under the terms of a performance bond agreement, a surety company could commit to responsibility for all claims and expenses for decommissioning up to a specified limit. Another form of financial guarantee will be required where the estimated cost of the decommissioning exceeds the value of the surety bond.
Surety bonds should name the CNSC as a beneficiary and the insurance or bonding agents should be Canadian companies subject to Canadian regulatory oversight.
Insurance policies may be acceptable financial guarantee instruments provided a standard insurance policy is developed and accepted by the CNSC.
4.6 Expressed commitments from Canadian government entities
Expressed commitments from a Canadian federal, provincial or territorial government, may be acceptable financial guarantee instruments if used to cover all otherwise unfunded aspects of decommissioning.
Expressed commitments from a Canadian provincial or territorial government are restricted to guarantees over which the federal government has rights of offset with respect to transfer payments as a method to enforce the guarantee if it becomes necessary.
Universities and hospitals must maintain a letter of commitment acknowledging the responsibility and liability for the decommissioning of the site. The letter of commitment must be signed by a person of authority at the institution .
Institutions that operate research reactors, such as SLOWPOKE reactors, should maintain adequate financial guarantees to bring the facility to a safe state, including removal of fuel and radioactive and hazardous materials from the site. The remaining cost for completing the decommissioning of the facility may be covered by a letter of commitment acknowledging the responsibility and liability of decommissioning. The letter of commitment must be signed by a person of authority at the institution.
4.7 Other types of instruments
Other types of financial guarantee instruments may be considered by the Commission as part of the licensing or renewal process. In all cases, the financial guarantee instrument must satisfy the general acceptance criteria listed in section 4. Since parent company guarantees and pledges of assets do not satisfy the acceptance criteria listed in section 4, they are not considered acceptable financial guarantee instruments.
5. Administration of Financial Guarantees
Financial guarantees are administered by clearly defined and legally-enforceable arrangements acceptable to the CNSC. These arrangements must be structured to ensure that the financial guarantee provided by the applicant or the licensee includes the following terms:
5.1 Access to funds upon demand
The CNSC must be assured that it can, upon demand, access or direct adequate funds if a licensee is not available to fulfill its obligations for decommissioning. The funds must be structured such that the instrument can be drawn upon only with the prior acceptance of the CNSC and that such pay-out is not prevented, delayed or compromised, and must be structured such that the instrument can provide full assurance of value.
5.2 Separation of financial guarantee from licensee’s other assets
The financial guarantee arrangements must be structured to ensure that the funds or securities provided by the applicant or licensee to guarantee funding for an approved decommissioning plan are separated from its other assets. This might require the inclusion of terms restricting access to, or use of, monies realized from the fund or securities.
Withdrawals from a fund, or access to monies realized from other security vehicles must only be permitted for approved purposes; in particular, to pay for approved decommissioning activities, or to refund excess monies to the licensee.
5.3 Maintenance on a continuous basis
Financial guarantee instruments must be automatically renewed and must include provisions for advance notice of termination or intent to not renew.
The term of a surety, insurance or other security vehicle should be open-ended, or, if written for a specified term, must be renewed automatically unless 30 days or more prior to the renewal date the issuer notifies the CNSC (as the beneficiary) and the licensee of any intention not to renew.
5.4 Replacement of financial guarantee
If the licensee or applicant fails to provide a replacement acceptable to the CNSC within 10 days after receipt of notification of cancellation, the terms of arrangement should further provide that the full face value of the instrument may automatically be paid into an account which is controlled by the federal government (either the CNSC or the Receiver General for Canada) or by a Canadian chartered bank listed in Schedule I or II of the Bank Act prior to expiration, without proof of forfeiture required. The value of the instrument must be payable, for purposes of funding decommissioning activities.
5.5 Signing officers
Licensees must provide, and continually update, a list of signing officers who have the requisite corporate or governmental authority to bind the corporation or the government as applicable.
6. Reporting Requirements
Licensees are required to report annually on the status and the validity of their financial guarantee. Licensees must indicate if their financial guarantee remains valid, in effect and sufficient to meet decommissioning needs according to the most up-to-date decommissioning plan .
For certain licensees, additional requirements for reporting on financial guarantees may be specified in the licence conditions handbook.
Part I: Financial Guarantees for the Decommissioning of Nuclear Facilities and Activities
Part I of this document provides information to applicants and licensees with regard to the CNSC’s requirements and guidance for establishing financial guarantees for decommissioning of licensed facilities and activities authorized under Class IA and B nuclear facility licences, uranium mine and mill licences, and waste nuclear substances licenses.
The Nuclear Safety and Control Act (NSCA) and associated regulations require applicants and licensees to make adequate provision for the safe operation and decommissioning of existing or proposed operations.
A licence may contain conditions requiring licensees to have acceptable decommissioning plans in place, and an acceptable financial guarantee that must remain valid, in effect and sufficient to meet decommissioning needs according to the most up-to-date decommissioning plan.
8. Planning for Decommissioning
Planning for the decommissioning of a facility is an integral part of the lifecycle planning of a facility. The lifecycle stages of a facility include: siting; design and construction; commissioning; operation and maintenance; final shutdown; and decommissioning. Planning for decommissioning is an ongoing process and should be considered at each lifecycle stage of the facility.
Applicants and licensees are required to submit a preliminary decommissioning plan (PDP) for the lifecycle stages from siting to final shutdown, and a detailed decommissioning plan (DDP) with an application for a licence to decommission.
The PDP should be filed with the CNSC as early as possible in the lifecycle of the facility. The PDP should be revised at least every five years or as required by the Commission.
The DDP is filed with the CNSC prior to beginning of decommissioning activities. Requirements and guidance for decommissioning planning for CNSC-regulated activities and facilities are provided in draft REGDOC-2.11.2, Decommissioning and CSA standard N294‑09, Decommissioning of facilities containing nuclear substances. Decommissioning plans can vary in complexity and detail in accordance with specific circumstances but must be sufficiently detailed to enable credible estimates of the amount of financial guarantees.
9. Cost Estimates for Decommissioning
The cost estimate for decommissioning should be based on the most up-to-date decommissioning plan and should reflect the assumed decommissioning strategy and end state of the facility.
The decommissioning cost estimates may vary depending on the stage in the facility’s lifecycle. In the case of estimates undertaken at the conceptual design stage of a project, the purpose is:
- to enable designers and client organizations to establish overall project costs
- to inform the long-term financing process to provide for future funds when a facility will be decommissioned.
Later, when the decommissioning project planning has advanced as a facility nears the end of its period of operation, the cost estimate forms part of the basis for the detailed decommissioning planning.
Various approaches to determine the level of cost estimate accuracy exists. Organizations, such as the Association for Advancement of Cost Engineering (AACE International) have developed guidelines for estimating cost for different industries. Guidance establishing the cost estimate level of accuracy is provided in appendix B.
10. Requirements for Costs To Be Included
Cost estimates must include all decommissioning activities from operations, during shutdown to the final release from regulatory control. The cost estimate for decommissioning must address the cost of the following principal activities, if applicable:
- preparation for final shutdown
- facility shutdown activities
- additional activities for safe enclosure (if applicable)
- decontamination and dismantling activities
- waste processing, storage and disposal, including used fuel
- project management, engineering and site support
- site clean-up, landscaping and restoration (if required)
- long-term management of radioactive waste and used fuel (if applicable)
- long-term monitoring and maintenance of the site and institutional control (if applicable)
- miscellaneous expenditures
The applicant or licensee must estimate the cost for all activities included in their decommissioning plan.
11. Cost Categories
Four cost categories should be defined for each principal activity:
- labour cost: payments to employees including social and health benefits
- investment cost: capital/equipment/material cost
- expenses: consumable, taxes, insurance, etc.
- contingencies: a specific provision for unforeseeable elements of cost within the defined project scope
The applicant or the licensee should reflect local construction rates for labour, reasonably conservative estimates for materials, equipment and administrative expenses.
Example of standardized definition for cost categories for all major activities is presented in appendix C.
12. Presentation of Cost Estimate
When developing a decommissioning cost estimate, consideration should be given to the presentation of cost estimate. The method most widely used as a platform for presenting the cost estimation for establishing the funding for decommissioning is the work breakdown structure (WBS).
The WBS elements are arranged in a hierarchal format. The first level identifies the principal activities of the decommissioning project as listed in section 10 of this document. The second level presents the major cost groupings under which project costs would be gathered. The first and second levels are usually aggregations of the typical activities identified in the third level. The cost associated with each activity could be subdivided according to the four cost categories shown in figure 1.
An example of the hierarchal cost structure used by the International Structure for Decommissioning Costing (ISDC) is presented in figure 1.
Figure 1: Hierarchal cost structure as per International Structure for Decommissioning Costing
Subsequent levels to the cost structure could be added in order to distinguish costs related to specific parts of the facility or specific periods of decommissioning project. The ISDC summary of cost item hierarchy is presented in appendix D. The detailed itemization presented in the aforementioned appendix provides general guidance on cost to be included in the estimate. The applicants and licensees should ensure that costs for all activities described in the decommissioning plan are reflected.
The approaches to cost estimate vary depending on the primary objective of the cost estimate, the facility lifecycle stage and the advancement of decommissioning planning. Brief description and comparison of those estimating methods is provided in table 1 in appendix E.
13. Elements of Cost Estimates
When developing a facility decommissioning cost estimate, the four basic elements to a cost estimate should be considered: Basis of estimate, structure of estimate (work breakdown structure [WBS]), schedule and uncertainty analysis. These four elements are described in detail in the following sections.
13.1 Basis of estimate
The basis of estimate (BOE) is the foundation upon which the cost estimate is developed. A well-documented BOE should fully reflect the current decommissioning plan for the facility. The BOE should provide a detailed description of the decommissioning project including:
- assumptions and exclusions, including the reference year and the currency used
- boundary conditions and limitations – legal and technical (e.g., regulatory framework)
- decommissioning strategy description
- end state of the facility
- stakeholder input/concerns
- facility description and site characterization (radiological/hazardous material inventory)
- waste management (packaging, storage, transportation, and disposal)
- used fuel management (activities included into a decommissioning project)
- sources of data used (actual field data vs. estimating judgment)
- cost estimating methodology used; e.g., bottom-up
- the basis for determining contingency, estimating uncertainty and risk
- discussion of techniques and technology to be used
- description of computer codes or calculation methodology employed
- schedule analysis
- uncertainty analysis
The cost estimate for decommissioning should provide that, if impacts of proposed operations are difficult or impossible to estimate with precision, the worst-case scenario or “decommissioning tomorrow approach” must be used. The applicants and licensee should not assume drawdown of nuclear substances or hazardous waste during operations. A credit for salvage of materials or equipment is not allowed. For the purpose of the cost estimate, they mustbe considered waste.
The cost estimate for decommissioning must cover the entire decommissioning project including the need for post-closure licensing, monitoring, surveillance and maintenance and institutional control.
13.2 Structure of estimate
The WBS is used to categorize cost elements and work activities into logical groupings that have a direct or indirect relationship to each other and to determine how they affect the overall cost of the project. To that end, the work scope cost elements are broken down into activity-dependent, period-dependent, and collateral costs as defined in the following paragraphs.
13.2.1 Activity-dependent costs
Activity-dependent costs are costs associated directly with performing decommissioning activities. Examples of such activities include decontamination; removal of equipment; demolition of buildings; and waste packaging, shipping and disposal. These activities lend themselves to the use of unit cost and work productivity factors (or work difficulty factors) applied against the facility and structure’s inventories to develop the decommissioning cost and schedule.
13.2.2 Period-dependent costs
Period-dependent costs include those activities associated primarily with the project duration: engineering, project management, dismantling management, licensing, health and safety, security, energy and quality assurance. These are primarily management staffing level costs, developed by estimating the manpower loading and associated overhead costs based on the scope of work to be accomplished during individual phases within each period of the project.
13.3 Collateral and special item costs
In addition to activity and period-dependent costs, there are costs for special items, such as for procurement of construction or dismantling equipment, site preparation, insurance, property taxes, health physics supplies, liquid radioactive waste processing and independent verification surveys. Such items do not fall in either of the other categories.
Contingency is a work scope element of cost and it should be applied to the base cost to account for unforeseen elements of cost that are likely to occur. Because of the unique nature of this element of cost, the application of contingency is further described in section 13.5 of this document.
The duration of a decommissioning project affects its cost importantly through the period-dependent costs and the selected technology for the activity-dependent work. The project schedule is an integral part of a cost estimate.
The preparation of a schedule is a well-developed process for which proven software programs are available.
The breakdown by project phase ties together all related activities in a chronological sequence to better define the work scope and schedule. The schedule work breakdown structure should be the same as the cost estimate work breakdown structure.
Activity sequencing requires the determination and documentation of the relationship between activities. Work process flow charts should be used to structure the relationship between activities.
At the early stages of decommissioning planning and cost estimation, a summary-level schedule may be provided that includes the principal activities and a more detailed schedule may be provided later based on the detailed decommissioning planning.
13.5 Uncertainty analysis
The BOE should fully define the boundaries of the decommissioning project scope and set out the basis for estimating the base cost and the associated uncertainties.
Contingencies are defined as unforeseeable elements of cost within the defined project scope, while uncertainties may also cover unforeseeable elements outside the defined project scope, or the changes in the scope of the project as defined.
The base cost is first calculated on the basis of standard conditions where activities are performed within the defined project scope, without delays, interruptions, inclement weather, tool or equipment breakdown, labour strikes, waste shipment problems, disposal facility waste acceptance criteria changes, or changes in the anticipated shutdown conditions.
The following three approaches for applying contingency could be used:
- for the entire decommissioning project
- for groups of decommissioning activities
- for individual decommissioning activities
Licensees should add contingencies to the base cost as a specific provision for unforeseeable elements of cost within the defined project scope, which are likely to occur. Licensees must provide a justification of the contingencies applied to the cost estimates and link them to the cost estimate category. Contingencies are an integral part of the cost estimate and are expected to be spent during the realization of the decommissioning project.
The outside-of-project scope uncertainties might be related to legal, regulatory, technical, and market-related uncertainties that might have significant economic and cost implications.
Licensees must address the outside-of-project scope uncertainties if there is a significant change to the defined scope of the project or if any of the outside-of project scope uncertainties are likely to result in a more than 5% change of estimated cost for the decommissioning project.
14. Development of the Financial Guarantee
The cost estimates are first prepared assuming that the decommissioning will be executed at the time the cost is estimated called current value. However, the time required to fully decommission can vary widely and has a significant impact on the calculation of the cost of decommissioning required for the financial guarantee. Various factors must therefore be outlined in the estimate of the financial guarantee requirement:
- Inflation rate: The percentage increase in the price of goods and services annually. The rate of inflation used should be from a reasonable and credible source, such as from the Bank of Canada. Licensees must factor in inflation to ensure that there are sufficient funds reserved even, when consideration for price increases is factored in.
- Discount rate (or expected rate of return on investment): In cases where the funds are invested, the expected rate of return that will be earned by the funds over time must be estimated. This expected rate of return should be supported by assumptions such as historical performance of the fund over time, the risk of the portfolio etc.
Another element that is important when performing this calculation is an estimate of when various elements of the work will be performed. Disbursements or planned spending must be factored in.
Starting with current value of the money, then applying the inflation rate and the discount rate, results in the net present value of funds required to be invested today, to ensure there are sufficient funds available for decommissioning in the future.
14.1 Current value
Cost estimates are first prepared in constant dollars which assumes that the expenditures occur at the time the estimate is prepared. This presents the current value of the liability and does not depend on the timing of the decommissioning activities.
14.2 Cash flow and planned disbursements
Schedule of cash flow and planned disbursements for decommissioning must also be submitted in order to calculate the net present value of decommissioning requirements
14.3 Net present value
The net present value presents the current dollar value of estimated future cash expenditures. It depends on the timing of decommissioning activities and expected expenditure profile.
In order to determine how much money is required today to pay for future liability, economic assumptions with respect to inflation and interest rate must be considered. The applicant and the licensees must indicate the inflation rate and interest or discount rate used in calculations and justify the validity of the selected rates and assumptions.
As stated above, many decommissioning activities take place over a number of years, so it is important to ensure there are sufficient funds available today to cover costs that will be incurred years into the future.
15. Review of Financial Guarantees
Licensees must ensure that the financial guarantee in place remains valid, in effect and sufficient to meet decommissioning needs according to the most up-to-date PDP. Therefore, licensees must revise their financial guarantee at a minimum every five years or earlier when requested by the Commission.
Licensees may request a review of their financial guarantees by the CNSC at any time.
Licensees must submit the updated financial guarantee for review by CNSC staff and acceptance by the Commission.
Part II: Financial Guarantees for Termination of Licensed Activities
Part II of this document applies to holders of nuclear substances and radiation devices, prescribed equipment, and Class II facilities licensees. These licensees must ensure that they are financially responsible for the termination of the activities authorized by their licence. The CNSC has developed an insurance based financial guarantee program to ensure that the Crown is not held financially responsible in the situation where a licensee has failed to properly terminate licensed activities.
17. Financial Guarantee Program
The insurance based financial guarantee program was developed exclusively for CNSC licensees holding licences for activities, such as nuclear substances and radiation devices, prescribed equipment, and Class II facilities. Under this program the CNSC is the insured party and the beneficiary. Licensees that participate in this program contribute to the cost of the insurance policy, in proportion to their liability. Liability is calculated on the basis of a formula that prescribes an estimated liability for each unit of prescribed equipment and sealed source as well as a room or laboratory where open source material is used.
Additional information on financial guarantees for nuclear substances and radiation devices and prescribed equipment and Class II facilities can be found on the CNSC website.
18. Alternatives to Financial Guarantee Program
The financial guarantee program is flexible in situations where a licensee’s activities do not meet the formula as prescribed. In these situations a licensee has the option to propose its own financial guarantee for review and acceptance by the Commission following the established principles of section 3 and 4 of this document.
19. Review of Financial Guarantees
Financial guarantees for licences are reviewed annually by the CNSC staff or as required by the Commission, to ensure that coverage is sufficient for the licensed activities.

Appendix B: Estimate Grades and Classification
A universally accepted standard for developing decommissioning cost estimates has not been established. However, organizations such as the Association for the Advancement of Cost Engineering (AACE International) have developed guidelines for estimation cost for different industries.
AACE International and the Construction Industry Institute have established guidelines and procedures for estimating costs. These guidelines rank cost estimates as Grades A, B, or C, depending on their level of accuracy.
Grade C (accuracy of ±25% to 30%)
Grade C cost estimates are known as order-of-magnitude cost estimates. They are performed quickly by using shortcut techniques such as
- escalating and/or scaling up from previous estimates
- cost curves
- preliminary process design and equipment sizing without plot plans or major equipment quotations
It is likely that the overall scope of the project has not been defined.
Grade B (accuracy of ±15% to 20%)
Grade B cost estimates are known as budgetary cost estimates. They can be developed when the scope of the project has been defined but the detailed planning has not been performed. For large projects, they can be developed as soon as the preliminary process flow diagrams, preliminary plot plans, and equipment sizing have been completed. On smaller projects, estimates are developed when approximately 10% of the engineering is completed.
Grade A (accuracy of ±10%)
Grade A cost estimates are known as definitive cost estimates. They can be developed when the scope of the project is well defined and the detailed planning is prepared. For large projects, a Grade A estimate are prepared when the engineering flow diagrams, facility plans, and equipment lists are completed, and design has progressed to the stage required for the bidding process. For small projects, more engineering detail is necessary, and 30% to 50% of the engineering might be required to be completed.
Cost estimate classes
AACE International describes a classification system for cost estimates in the process industry (see table 1). In general, the accuracy of the cost estimate is higher as the level of project definition is increased. Decommissioning cost estimates prepared for the PDP are typically prepared as Class 4 study-type cost estimates. For additional information refer to the AACE International’s Required Skills and Knowledge of Cost Engineering.

Appendix C: Standardized Definitions for Cost Categories
This appendix provides information on standardised definitions for cost categories for all major activities. These definitions have been developed by the International Structure for Decommissioning Costing (ISDC) .
For each cost item, four cost categories have been defined:
- labour costs
- investment costs (capital, equipment and material costs)
1. Labour costs
Labour costs are defined as costs calculated on the basis of the workload for a particular cost item and the labour cost unit rate, including:
- contributions to social security and health insurance
- company contributions to pension scheme and fringe benefits
Investment costs (capital, equipment and material costs)
Investment costs are defined as costs for:
- equipment to be used for a particular cost item
- machinery to be used for a particular cost item
Expenses are defined as costs for consumer items or expendable items, or as costs for other expenditures related to decommissioning cost items where applicable, such as:
- spare parts
- protective clothing
- travel expenses
- legal expenses
- value added tax
- consultants costs
- quality assurance costs
- office material
- heating costs
- water costs
- electricity costs
- computer costs
- telephone/fax costs
- public relation
- decommissioning authorisation
- income from asset recovery (“negative expenses”)
Contingency, added to individual cost items of the standardised listing, is a specific provision for unforeseeable elements of costs within the defined project scope. Any impacts on cost outside of the scope of the decommissioning project are not considered.
Appendix D: International Structure for Decommissioning Costing - Cost Item Hierarchy
This appendix provides information from the International Structure for Decommissioning Costing (ISDC) . The ISDC was developed as a presentation platform for standardized listing of costs within the scope of decommissioning planning. Note that cost estimation for decommissioning of nuclear facilities can vary widely in format, content and practice.

Appendix E: Approaches to Cost Estimation
The Nuclear Energy Agency document The Practice of Cost Estimation for Decommissioning of Nuclear Facilities provides a comparative overview of the cost estimation methods and their advantages and disadvantages. It is summarized in the following table.
Table 1: Estimating method comparison
In this building blocks technique, a work statement and set of drawings or specifications are used to extract material quantities required for executing each discrete task performed in accomplishing a given activity. From these quantities, direct labour, equipment and overhead costs can be derived.
Most accurate as it accounts for site-specific radiological and physical inventory. Relies on unit cost factors (UCFs).
Requires detailed description of inventory and site specific labour, material and equipment costs for the UCFs.
Specific analogies depend upon the known cost of an item used in prior estimates as the basis for the cost of a similar item in a new estimate. Adjustments are made to known costs to account for differences in relative complexities of performance, design and operational characteristics.
Accurate if prior estimates are appropriately adjusted for size differences, inflation and regional differences in labour materials and equipment.
Adjustments as noted may require detailed documentation and introduce approximations that reduce accuracy.
Parametric estimating requires historical databases on similar systems or subsystems. Statistical analysis is performed on the data to find correlations between cost drivers and other system parameters, such as design or performance. The analysis produces cost equations or cost estimating relationships that may be used individually or grouped into more complex models.
Suitable for use for large sites where detailed inventory is not readily available. Suited for Order of Magnitude estimates.
Approximations based on areas or volumes introduce additional inaccuracies. There is no way to track actual inventory. Not suited for project planning of work activities.
Cost review and update
An estimate may be constructed by examining previous estimates of the same or similar projects for internal logic, completeness of scope, assumptions and estimating methodology.
Suitable for large sites where detailed inventory is not available. Suited for update of previous estimates, or order of magnitude estimates.
There is no way to track actual inventory. Generally not suited for project planning of work activities.
An expert opinion technique may be used when other techniques or data are not available. Several specialists may be consulted iteratively until a consensus cost estimate is established.
An expert opinion technique may be used when other techniques or data are not available. Several specialists may be consulted iteratively until a consensus cost estimate is established.
Expert opinion may not be specific to the work activities. May not reflect the radiological limitations of the decommissioning project.
