The Canadian Nuclear Safety Commission re-publishes three regulatory documents

News Release

August 30, 2017 – Ottawa, ON

The Canadian Nuclear Safety Commission (CNSC) has re-published three regulatory documents:

  1. REGDOC-2.5.7, Design, Testing and Performance of Exposure Devices (formerly RD/GD-352)

  2. REGDOC-2.6.1, Reliability Programs for Nuclear Power Plants (formerly RD/GD-98)

  3. REGDOC-2.6.2, Maintenance Programs for Nuclear Power Plants (formerly RD/GD-210) 

The new versions contain no new requirements; only the following administrative changes were made to align existing content with the CNSC's updated naming convention and format for regulatory documents: 

  • new title

  • new cover and inside cover

  • updated references (where appropriate)

  • a sentence in the glossary pointing to REGDOC-3.6, Glossary of CNSC Terminology

  • new back page showing the CNSC’s regulatory document series

REGDOC-2.5.7, Design, Testing and Performance of Exposure Devices, provides guidance on the design, testing and performance of exposure devices to apply for certification under section 12 of the Nuclear Substances and Radiation Devices Regulations.

This document supersedes RD/GD-352, Design, Testing and Performance of Exposure Devices, published in January 2012.

REGDOC-2.6.1, Reliability Programs for Nuclear Power Plants, sets out requirements and guidance for the development and implementation of a reliability program for nuclear power plants in Canada. The essential elements of a reliability program, including reliability assessment monitoring, are also described in this document

In addition to the administrative changes noted above, the following bullet was added to the list in section 3.1.4:

  • “As per REGDOC-2.5.2, section 7.6, not all SSCs important to safety identified in the design phase will necessarily be included in the reliability program.”  

This document supersedes RD/GD-98, Reliability Programs for Nuclear Power Plants, published in June 2012.                                        

REGDOC-2.6.2, Maintenance Programs for Nuclear Power Plants, sets out the requirements and guidance with regard to maintenance programs for nuclear power plants (NPPs). An NPP maintenance program consists of processes and procedures that provide direction for maintaining structures, systems and components of the plant. 

In addition to the administrative changes noted above, the following duplicate text was removed from the list in section 3.4.2:

  • “Parameter expectations should be provided to allow verification of correct operational states and to detect any abnormal conditions.” 

This document supersedes RD/GD-210, Maintenance Programs for Nuclear Power Plants, published in December 2012.

The CNSC regulates the use of nuclear energy and materials to protect the health, safety and security and the environment; to implement Canada’s international commitments on the peaceful use of nuclear energy; and to disseminate objective scientific, technical and regulatory information to the public.
