IEEE 1205-1993

This document provides the guidelines for assessing, monitoring, and mitigating aging degradation effects on Class 1E equipment used in nuclear power generating stations.

The purpose of this document is to supplement existing IEEE nuclear standards in assessing aging degradation effects. The methods described herein can be used to identify the performance capability of Class 1E equipment beyond its qualified life.

New IEEE Standard - Superseded. The guidelines are provided for assessing, monitoring, and mitigating degradation of Class 1E equipment used in nuclear power generating stations due to aging. The methods described can be used to identify the performance capability of Class 1E equipment beyond its qualified life. A discussion of stressors and aging mechanisms is included. If aging considerations have been satisfactorily addressed through other means (e.g., equipment qualification), then use of this guide may not be warranted. For some equipment, only partial application of this guide may be warranted.
