RI-IST concentrates testing resources on high significant components, reduces exceeded tests, increases plant’s availability, lows down Dose rate on the plant’s staff and achieves cost saving on plant’s operation and maintenance under nuclear safety expectation. Further more, implementing RI-IST also gives a feature on prospective licensing change basis to licensee. Based on current trend in United States, numbers of nuclear power plants have implemented RI-IST as an alternative program for their Inservice Testing program. Several investigations also enclose both probability risk assessment and traditional engineering analysis concepts into practical practices for the nuclear industry either domestic or international. With completed regulations regarding to risk-informed implementation, certain regulation provides clear rules for both management and licensee to follow and be able to determine on decision making for Inservice Testing program. Implementing Risk-informed also identifies the vulnerabilities of the structure, system and components which are very helpful for the plant’s staff in order to improve SSCs reliability and maintain plant’s defense-in-depth. This study will focus on safety related Check Valves under Inservice Testing program in BWR type nuclear power plant. As an initiating RI-IST, this study chooses check valve as evaluating object. Due to check valve composing less regulatory criteria and quantities under IST program, therefore, data acquisition and management are easier than other types of valves in the system during analyzing process. This evaluating establishment will incorporate with current probabilistic risk assessment and traditional analytical method relevant techniques to assess safety significant for the check valves under current Inservice Testing program. With this initiating achievement, it can provide a cornerstone for the further study on the other types of valves and pumps in RI-IST program and be able to provide valuable references for proposing license change to the licensee.
