Component failures that lead to reactor shutdowns and scrams

Description
This paper summarizes the operating experience data compiled from 35 operating US Light Water Reactors (LWRs) to identify the principal components/systems related to reactor scrams and reactor shutdowns. The data base utilized to identify the scram causes is developed from an EPRI-utility sponsored survey conducted by SAI coupled with data from the USNRC Gray Books. The approach of this study is to identify and rank, according to frequency and plant age, the historical causes of reactor scrams and shutdowns, particularly those related to component failures, human error, or faulty procedures. An overall summary of the relative frequency of scrams and manual shutdowns is presented along with a ranking of the principal components contributing to scrams and manual shutdowns. The trend of the causes of plant scrams as a function of plant age is also investigated
