概要
The damage caused by primary water stress corrosion crack (PWSCC) has been revealed in Reactor Vessel Head Penetration Nozzles with alloy 600 domestically a nd internationally in recent years. Bottom Mounted Instrumentation which has the same structure as Head Penetration Nozzle is also necessary to consider the occurrence of damage. The guideline has been examined and studied to clarify the application of inspection techniques and preventive maintenance method, the approach to the evaluation for acceptance level of continuous operation and inspection frequency. The summary of this guideline is introduced in this paper.
