GUIDELINE ON APPLICATION PROCESS OF TECHNIQUES DEVELOPED FOR REPAIR, REPLACEMENT AND MITIGATION ACTIVITIES

摘要

The process from the engineering development to actual application of the new techniques used for the maintenance activities for Japanese nuclear power plants' (NPPs) component in operation, the JANTI Guideline, "Guideline on Application Process of Techniques Developed for Maintenance Activities" was developed to propose clarification activities to be checked or examined in each stage throughout process. The guideline focuses on techniques used for especially such remedial activities as repair, replacement and mitigation of ageing. In engineering development stage, all information on the new techniques are provided to be checked or examined at each stage of the process followed further, such as code/standard formulation stage. It is important to carry out share recognition for the activities, which should be performed in each process in the prompt application to the actual plant system efficiently, among the persons or organizations concerned.
