1.26. Another potential area of concern relates primarily to purchasing valve assemblies by a licensee or its agent. Application of the specification requirements of this standard to preselected valve assemblies could adversely affect current purchasing procedures depending on whether purchasing is done individually or in groups of valve assemblies. Recommendations The staff intends to apply the guide initially to active valve assemblies. The guide would be acceptable for use with all valve assemblies in systems important to safety, but application to other than active valves should be at the discretion of the licensee because of the potential impact on current procedures. Experience acquired through use of the standard with active valve assemblies will provide guidance for wider application in the future. 1.148-5 UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.
