Description

In this paper, the risk assessments on the change of AOT and the PM during power operation of the major safety systems for Ulchin Units 3 and 4 were performed to identify the possibility of their on-line PM. The results of this study show that the current AOT of LPSIS, SCS, and CSS can be increased to 7 days and that of EDG to 10 days. Also, the results show that the on-line PM of LPSIS, SCS, CSS, EDG, ECWS, ESWS, and CCWS for Ulchin Units 3 and 4 can be performed without greatly increasing the risk. (author)
