The Application of Risk-Informed Management Index in NPPs Risk Management

Abstract

With domestic NPP units increased, it is urgent to establish a more reasonable regulation way with full emphasis on plant significant items. This paper, based on the deterministic methodology and engineering judge, researches the risk-informed management index by applying SDP into events risk evaluation at all sites, which can help forecast the risk trend next month and pre-determine the current NPP risk status of each month with established risk judge criteria. Furthermore, some information and suggestions about risk significant events and risk prediction values are also mentioned in this paper, as well as some examples, in order to offer some references for management level to accomplish the decision-making.
