Implementation of CNSC Regulatory Guide G-323 at Pickering Nuclear Generating Station

Abstract

The Minimum Staff Complement (MSC) is the minimum number of people required to be present on a given shift to ensure safe and reliable operation of the nuclear facility, while maintaining an adequate preparedness level in handling all possible emergency scenarios. In 2009-2010, Ontario Power Generation (OPG) examined its MSC at Pickering using the newly issued regulatory guidelines specified in CNSC Guide G‑323 ‘Ensuring the Presence of Sufficient Qualified Staff at Class I Nuclear Facilities – Minimum Staff Complement’. This was the first project of this nature in the Canadian Nuclear industry to be executed using G-323. The following paper provides an overview of the methodology that was developed to demonstrate Pickering’s alignment with G-323 in addition to the successes and challenges of the project.
