Abstract

Abstract

In order to support an emergency diesel generator of Tianwan Nuclear Power Plant Units 1 and 2 for returning to the factory for overhaul, this paper proposes an optimization plan for the unavailability recovery time of an emergency diesel generator, and adopts a combination of determinism and probability theory. The risk-informed approach analyzes the feasibility of the optimization plan. The analysis results show that the unavailability recovery time optimization of an emergency diesel generator meets the requirements of relevant regulations and guidelines and traditional engineering analysis, and the risk to the power plant is small and acceptable. An emergency diesel generator can be returned to the factory for overhaul.
