APPLICATION OF THE GIP METHODOLOGY TO DEMONSTRATE SEISMIC ADEQUACY OF NEW AND REPLACEMENT EQUIPMENT AND PARTS IN USI A·46 PLANTS

This paper discusses the guidance developed by the Seismic Qualification Utility Group (SQUG) for application of GIP methods to new and replacement equipment and parts. These SQUG guidelines address considerations unique to application of the GIP to new and replacement items including licensing requirements. differences between installed items and items yet to . be procured, differences in demonstration of seismic adequacy of parts versus equipment and equipment vintage issueS. The SQUG guidance can be used by USJ A-46 utilities to develop plant­ specific procedures for use of GlP methods whicb will satisfy their licensing basis seismic requirements. The resulting methods will be significantly more cost effective than current equipment qualification methods involving testing andlor analysis and will provide safety margins consistent with those demonstrated during resolution of US! A-46.
