Risk-informed reliability-focused decision analysis support for effective facility change management

摘要

Application of the risk-informed asset management method described herein provides rigorous, systematic, prudent decision-making support for proposed changes to Balance-of-Plant (BOP) equipment (i.e., equipment other than the nuclear steam supply system and conventional standby safety systems) and associated operation and maintenance practices and policies at the South Texas Project Electric Generating Station (STPEGS). The phased approach helps keep the scope of the supporting analyses at a level that supports and promotes reasonable change development efforts and costs. This risk-informed asset management method can easily be adapted to a wide variety of complex systems, processes, and facilities. Consistent, continuous application and improvement of the methods described herein will significantly aid facility decision-makers in optimizing resources to maximize return-on-asset for over the facility life cycle.
