Comprehensive aging assessment of circuit breakers and relays

Description
As part of the NRC Nuclear Plant Aging Research (NPAR) Program a comprehensive aging assessment was made of relays and circuit breakers. Relays and circuit breakers are important nuclear power plant equipment which are susceptible to degradation with time. This is a Phase II NPAR report which follows the NPAR strategy. Tests on naturally aged and degraded relays and circuit breakers were performed, in-situ measurements made and current, and improved methods for inspection, surveillance and monitoring (ISM) evaluated. Significant results described in this report were the identification of inspection, surveillance and monitoring methods which provide a higher level of assurance that aging will be detected and mitigated. The potential exists that implementation of the improved methods in nuclear plants would minimize and impact of aging and result in more cost effective maintenance on relays and circuit breakers
