The Canadian Nuclear Safety Commission (CNSC) has released, for public consultation, draft regulatory document RD-360 version 2, Life Management of Nuclear Power Plants and draft guidance document GD-360 Guidance for Life Management of Nuclear Power Plants.
RD-360, Life Extension of Nuclear Power Plants was published in February 2008. In May 2009, CNSC staff determined that updates to the document were needed. The scope has been broadened to include requirements for activities related to the end of operation of a nuclear power plant (NPP). Draft RD-360 version 2 also reflects updates in associated national and international guides and incorporates lessons learned from ongoing life-extension projects.
RD-360 version 2 sets out the requirements of the CNSC regarding activities a licensee must undertake in support of a project for long-term operation or to prepare for the end of operation of an NPP leading up to its decommissioning.
Long-term operation of an NPP denotes operation beyond the assumed design life of the plant. The end of operation is the final, permanent shutdown of reactor operation of an NPP. The NPP remains subject to its power reactor operating licence that authorizes activities during the transition period from reactor unit shutdown and safe state of storage until decommissioning.
RD-360 version 2 will supersede RD-360, Life Extension of Nuclear Power Plants, after it receives final approval by the Commission Tribunal and is published. Publication of RD-360 version 2 is planned for February 2012.
The associated draft guidance document GD-360 provides guidance on how these requirements may be met. Find out more about guidance documents.
