The Role of Automated Testing and Logging Tools in Fuel Handling I & C Refurbishment: Bruce A NGS FH Protective Replacement

Abstract

The replacement and upgrade of nuclear-related I&C systems forms an important part of the refurbishment and life extension of the CANDU fleet. Replacement of the DEC PDP-based fuel handling Protective computer at the Bruce A NGS has brought with it challenges in both design reimplementation, and in ensuring a smooth path through installation and commissioning. In order to achieve success, innovative approaches to in-field data logging and automated testing equipment for PLCs were needed. GEH-C's Automated Software Test Equipment and datalogger (ASTE/d) has been a key tool in ensuring verification and validation of replacement designs, test repeatability, and enhanced coverage, while contributing to project cost and schedule adherence.
