March 23, 1983 TO ALL LICENSEES OF OPERATING POWER REACTORS AND APPLICANTS FOR OPERATING

LICENSES (GENERIC LE1TER 83-15)

SUBJECT: IMPLEMENTATION OF REGULATORY GUIDE 1.150, "ULTRASONIC TESTING OF

REACTOR VESSEL WELDS DURING PRESERVICE AND INSERVICE EXAMINATIONS,

REVISION 1 "

The original version of Regulatory Guide 1.150, "Ultrasonic Testing of Reactor Vessel Welds During Preservice and Inservice Examinations," dated June 1981, was reviewed by the Ad Hoc Committee of the Electric Utility Industry. The Comnittee's review resulted in their recommending an alternative method, which was presented in 'Final Report - Reconmended Changes to Regulatory Guide 1.150,'

August 1982.

The NRC staff has evaluated the recommended alternative method in the report and finds it an acceptable alternative. Therefore, this alternative method has been added to the regulatory positions in Regulatory Guide 1.150, and this Revision 1 Is being issued as an active guide without prior issuance as a draft guide for comnent.

Except in those cases in which an applicant or licensee proposes an acceptable alternative method for complying with specified portions of the Co-mission's regu- lations, the method described in Revision I of the subject Guide will be used in the evaluation of (1) the results of inservice examination programs of all oper- ating reactors after July 15, 1981, and (2) the results of preservice examination program of all reactors under construction performed after January 15, 1982. The reconmendations of this guide are not intended to apply to preservice examinations that have already been completed. We recommend that all licensees modify their technical specifications if appropriate, to make them consistent with the recom- mendations in the subject Guide.

I

Any guidance in the subject Guide related to information collection activities has been cleared under OM Clearance No. 3150-0011, which expires April 30, 1985.
