Abstract

As a part of the post-Fukushima response, OPG and Bruce Power have enhanced their SAMG programs to provide the capability to respond to a wider range of event progressions such as multiunit events or IFB events. In many instances, these enhancements were adapted directly from a COG Joint Project undertaken by the CANDU industry. However, as a part of the station-specific SAMG updates, opportunities were identified to enhance the practical implementation of the COG recommendations. Most notably, these include an alternative approach to managing IFB events, a simplified approach to hydrogen management, and guidance on comparing between containment venting and leakage at elevated pressures. These enhancements are being exercised through a combination of tabletop exercises and drills to confirm usability. The outcome of this process is a SAMG program that retains key features from the COG work in a format that is readily integrated into the pre-existing SAMG for each station.
