INSTALLATION OF AN IRRADIATtD FUEL BUNDLE DISCHARGE COUNTER AT BRUCE NGS-B 3 000 MW(e) CANDU POWER STATION

Design, manufacture and Installation of an Irradiated fuel bundle discharge counter for the multi-unit CANDU Bruce NGS-B Generating Station Involved contributions from the International Atomic Energy Agency (Agency), designers (AECL), contractors, manufacturers, utility and the regulatory agency. The Installation at Bruce NGS-B was the first made by the Agency as a retrofit to a multi-unit CANDU reactor approaching Us first critical operation, where the whole project was the responsibility of the Agency and where the original design of the reactor had not had provision for the Agency equipment. The scheduling and Integration of the Installation Into the normal activities Involved 1n starting up a 3 000 HW(e) multi-unit generating station were successfully achieved. The Agency has demonstrated the capability and performance of the fuel discharge counter.
