Determination of the Allowable Operating Envelope for the Point Lepreau Special Safety Systems

Abstract

New Brunswick Power is systematically reviewing each special safety system to ensure that reliable operation is maintained and that the system is being operated in accordance with the safety analysis and vice versa. The ECC system is the first to be reviewed by a multi-disciplinary team, known internally at Point Lepreau as the DOA team (DOA is an acronym for Design, Operation, and Analysis). This paper reports on the review and discusses findings. Major benefits to the station arise from increased awareness, improved communication, and development of the basis for both safety analysis models and the operating envelope.
