2013

March 14, 2013: The CNSC has been published in the February edition of the British Medical Journal Open, outlining the results of one of the largest cohort studies on workers exposed to radium, uranium and γ-ray doses. In this published article, the CNSC and its collaborators presented the results of a study that looked at new cancer cases and deaths from uranium and radium processing workers in the Port Hope community. Overall, workers had lower mortality and cancer incidence compared with the general Canadian population. Read the technical abstract: Mortality (1950-1999) and Cancer Incidence (1969-1999) Of Workers in the Port Hope Cohort Study Exposed to a Unique Combination of Radium, Uranium and Gamma-Ray Doses.
March 5, 2013: The CNSC, in collaboration with Health Canada, has been published in the March 2013 edition of the Journal of Radiological Protection. In the published article, the authors presented the results of a study that looked at new cancer cases in the Port Hope community from 1992 to 2007. The study did not find any differences in cancer incidence in Port Hope compared to other similar communities and the general population. These findings are consistent with previous studies conducted in Port Hope and studies conducted elsewhere on populations living around similar facilities with similar environmental contaminants. Read the technical abstract: An ecological study of cancer incidence in Port Hope, Ontario from 1992 to 2007.

2012

November 15, 2012: Following a public hearing held on October 24, 2012, in Ottawa, Ontario, the CNSC announced its decision to authorize AECL to proceed with Phase II of the Port Hope Long-Term Low-Level Radioactive Waste Management Project, and to extend the licence expiry date to December 31, 2022.
September 10, 2012: On Saturday, September 8th, Cameco reported to CNSC and the Ontario Ministry of the Environment that there was an incident of uranium contamination spill from a solid waste storage bag on the premises of the Port Hope Conversion Facility. Due to heavy rainfall that day, some contamination may have entered the harbour through the stormwater drainage system, before it was contained and cleaned-up. Early analysis has indicated that this incident has not impacted the surrounding environment and there has been no risk to the general public. Nevertheless, Cameco is required to investigate the causes of the spill and take actions to prevent re-occurrence. For more information (Source: Cameco)
August 27, 2012: CNSC staff received notification from Cameco Fuel Manufacturing Inc. (CFM) of an unusual event at their facility on August 21, 2012. There was a localized spill of uranium dioxide powder at one of the transfer stations within the facility that resulted in one worker being exposed to uranium and three other workers potentially exposed during cleanup. The worker was wearing personal protective equipment, and was examined by medical personnel immediately. Early urinalysis tests on all four workers do not indicate abnormal results, however they were temporarily re-assigned as a precautionary measure. There was no risk to the surrounding environment and the general public as a result of this event. Recognizing the health and safety significance of this incident to workers, CNSC staff is monitoring CFM's response and subsequent investigation of this incident, and will follow-up through our planned compliance verification program.

March 22, 2011: CNSC request to all Class I nuclear facilities and uranium mines and mills in Canada pursuant to subsection 12(2) of the General Nuclear Safety and Control Regulations
March 7, 2011: Cameco reported to the CNSC a minor incident at the Port Hope Conversion Facility on February 11, 2011, that resulted in a lost time injury. An employee sustained minor injuries following an acid spill inside the UF6 plant and has returned to work. There were no releases to the environment, nor impact to the general public. CNSC staff have conducted a detailed follow-up on this event and continue to monitor the progress of the Cameco investigation. CNSC's project officers and inspectors are engaged in the regulatory oversight of the Conversion Facility throughout the year. The matter will be discussed at the Commission’s next regularly scheduled meeting on March 30, 2011.
February 11, 2011: The Canadian Nuclear Safety Commission (CNSC) will be holding a one-day information session at the Capitol Theatre located at 20 Queen Street, in Port Hope, Ontario on March 10, 2011.

2010

October 20, 2010: As part of the Port Hope trial resurvey and remediation project in Port Hope, private properties have been selected for clean-up by the Port Hope Initiative Management Office. The CNSC will actively verify processes and procedures developed by Atomic Energy Canada Limited (AECL) and the Low-Level Radioactive Waste Management Office (LLRWMO) for the soil remediation activities of properties in the Port Hope Area. CNSC staff will perform on site verification of the trial remediation to ensure the work is completed safely in accordance with the methods and procedures proposed by AECL, and to confirm that the properties have been cleaned up in a satisfactory manner.

Nuclear facilities in Port Hope

The Canadian Nuclear Safety Commission (CNSC) regulates numerous nuclear facilities in the vicinity of Port Hope, Ontario.

Uranium conversion facility

Cameco Corporation's Port Hope Uranium Conversion Facility is a nuclear substance processing facility licensed to process uranium trioxide into both uranium dioxide (UO 2) and uranium hexafluoride (UF6). UO 2 is used to manufacture fuel for power reactors in Canada, while UF 6 is exported to companies in other countries for enrichment and fabrication into fuel for nuclear power reactors around the world.

Nuclear fuel facility

The Port Hope Nuclear Fuel Facility is a nuclear fuel fabrication facility that manufactures nuclear fuel bundles for power reactors in Canada.It is owned and operated by Cameco Fuel Manufacturing Inc. (formerly Zircatec Precision Industries).

Radioactive waste management facilities

The Port Hope Radioactive Waste Management Facility comprises three separate sites within the Municipality of Port Hope.These are the Strachan Street Ravine consolidation site, the Pine Street Extension consolidation site and the Sewage Treatment Plant Temporary Storage Site. These sites no longer receive radioactive waste, and are in a storage-with-surveillance mode. They are overseen by the Government of Canada's Low-Level Radioactive Waste Management Office.

The Pine Street Extension Temporary Storage Site is a radioactive waste management site which is licensed to receive historic radioactive waste from construction activities within the municipality. This facility is also run by the Government of Canada's Low-Level Radioactive Waste Management Office.

The Welcome Waste Management Facility in Port Hope is owned and operated by Atomic Energy of Canada Limited and the Port Granby Waste Management Facility, located in nearby Clarington, is owned and operated by Cameco Corporation. These facilities, which house low-level wastes and contaminatedsoils, no longer receive new wastes. Their long-term management will beaddressed by the Port Hope Area Initiative.

In November 2008, regulatory action was taken when CNSC staff sent two Requests for Information letters to Cameco asking them to provide the CNSC with a characterization of the current effluent discharge and a review of its effluent treatment and pipeline design for the Welcome Waste and Port Granby Management Facilities. ]

CNSC personnel routinely inspect and evaluate nuclear facilities in the Port Hope area to verify compliance with regulatory requirements and licence conditions. They also visit Port Hope to inform the public, community members and other interested parties of current and upcoming issues related to regulation of the licensed facilities.

About 45 km west of Port Hope is the Darlington Nuclear Generating Station in Bowmanville, Ontario.
