During the inspections performed at the NPP, many system components are chec¬ke¬d. Traditional deterministic inspections are mostly based on the data from the known ope¬r¬a¬t¬i¬n¬g experience, without considering the risk significance of the components. One of the in s¬er¬v¬i¬ce inspection routes includes checking the components and pumping stations of ESW (Esse¬n¬t¬ial service water) system. For the system, it is shown that replacing the traditional determin¬is¬t¬i¬c inspections by risk informed ones will allow to correctly identify the components to be chec¬k¬ed during inspections, which will significantly increase the efficiency of inspection and reduce the probability of the system failure several times
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
