Project description

The Canadian Nuclear Safety Commission (CNSC) has received a licence application from Best Theratronics Ltd. (BTL) to consolidate four existing licenses for BTL's facility in west Ottawa into a single Class 1B licence. BTL is already licensed to import, export, transfer, and store radiological materials at their facility.  The proposed new Class 1B licence would include the existing licensed activities, in addition to the construction and operation (for testing purposes) of linear accelerators and cyclotrons.

The infrastructure associated with BTL's proposal to construct and operate linear accelerators and cyclotrons is already present in the BTL building, with two exceptions.  BTL would require undertaking the following activities:

  • retrofitting the building interior to add a shielding bunker for cyclotron testing up to 70 MeV
  • adding safety and security devices to areas of the facility (cells 1 through 3) that would be used for testing linear accelerators up to 25 MeV

CNSC authorization, in the form of a new Class 1B licence, is required for BTL to carry out their proposed activities, as per subsection 24(2) of the Nuclear Safety and Control Act (NSCA).

Before the CNSC can consider any licensing actions under the NSCA regarding BTL's proposal, an EA must be completed in compliance with the Canadian Environmental Assessment Act. The purpose of an EA is to identify the possible environmental effects of a proposed project, and determine whether these effects can be mitigated before the project is allowed to proceed.
