Project Description

The Canadian Nuclear Safety Commission (CNSC) has received notice from Bruce Power Inc. of its intent to apply for a licence amendment to restart Bruce Nuclear Generation Station (NGS) ‘A' Units 3 and 4.

The Units 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 Units 3 and 4;
  • activities required to allow Units 3 and 4 to be brought to operational status; and
  • continued generation of power by Units 3 and 4 over their planned operational life.

No new construction activities will be undertaken for this project, and no changes to existing approved waste management practices have been proposed.
