Description
All OPR1000 and APR1400 plants have been designed with the NSSS Integrity Monitoring System (NIMS), which generally includes four subsystems, i.e., Acoustic Leak Monitoring System (ALMS), Internals Vibration Monitoring System (IVMS), Loose Parts Monitoring System (LPMS) and RCP Vibration Monitoring System (RCPVMS). The NIMS design has been continuously improved in both System Design (SD) and Component Design (CD) aspects by KOPEC and WEC, respectively. As the NIMS evolved from YGN3 and 4, UCN3 and 4, YGN/UCN5 and 6, SKN/SWN1 and 2, and now SKN3 and 4, a total five times of major improvement have been implemented. The fifth (5th) design changes have been made for Shin-Kori Nuclear Power Plant Units 3 and 4 (SKN3 and 4), which are under construction as the first plant of APR1400. This paper briefly describes the SD and CD improvements for SKN 3 and 4 NIMS in order to provide public understanding
