FAILURE PREVENTION FOR NUCLEAR POWER PLANTS THROUGH PROACTIVE MANAGEMENT OF MATERIALS DEGRADATION (PMMD)

摘要

Failure prevention is central to the operation of nuclear power plants. To meet this goal there is growing interest in new and improved philosophies and methodologies for plant life management, which include the migration from reliance on periodic inservice inspection to include condition-based maintenance. A further step in the development of plant management is the move from proactive responses based on ISI to become proactive, through the investigation of the potential for implementation of a proactive management of materials degradation program and its potential impact on the management of LWRs.
