Project Description

The Canadian Nuclear Safety Commission (CNSC) has received notice of intent from Bruce Power for the modification of a condition of its operating licence for the Bruce A Nuclear Generating Station (NGS). The licence modification would authorize the restart of Units 1 & 2 at Bruce A NGS.

The proposal is to return Units 1 and 2 of Bruce A to service (operational status) and extend their life through the end of a potential Bruce Power lease in 2043. In addition, the proposal includes the possible extended operational life of Units 3 & 4 through 2043, as well as the potential use of Low Void Reactivity Fuel (New Fuel) in all 4 units at Bruce A. Authorizations required for the life extension of Units 3 and 4 and the use of New Fuel may be sought by Bruce Power as required at a later date. This would occur after Units 1 and 2 have been restarted if authorization to do so is provided by CNSC.

Bruce A Units 1 & 2 are currently in a defuelled guaranteed shutdown state. As a condition of its current licence, Bruce Power Inc. must obtain approval from the Commission before the reactors can be loaded with fuel and operated at power.

Before the Commission makes its decision on Bruce Power Inc.'s licence amendment application, an environmental assessment must be completed in compliance with the Canadian Environmental Assessment Act. The purpose of an environmental assessment 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.

The restart project consists of the following elements:

  • Activities required to refuel Bruce A Units 1 and 2.
  • Activities required to allow Units 1 and 2 to be brought to operational status.
  • Activities required to extend the planned operational life of these units to allow continued generation of power by Units 1 and 2 for an extended period to the end of a potential Bruce Power lease in 2043.

No new construction activities will be undertaken for the Bruce A return to service project; also, no changes to existing approved waste management practices or systems have been proposed.

Steps ahead:

  • Development of draft EA guidelines (scope document)
  • Approval of EA guidelines by Commission following a public hearing
  • Review of EA study report
  • Preparation of draft screening report
  • Public consultation on draft screening report
  • EA decision by Commission following a public hearing
