h U.S. NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT REGION III March 19, 1979 IE Bulletin No.78-12B ATYPICAL WELD MATERIAL IN REACTOR PRESSURE VESSEL WELDS Description of Circumstr.nces:
This Eulletin is a supplement to IE Bulletins 78-12 and 12A and all three documents must be collectively considered to provide an adequate response to the bulletins.
Following the issuance of IE Bult: tin 78-12A, members of the Office of Inspection and Enforcement staff met with representatives from the reactor vessel manufacturers and suppliers to discuss the requiremer.ts of the bulletins.
During these meetings, detailed interpretation of the data requirements was provided based on the manufacturer's respective methods of fabrication and record systems.
Recognizing that the scope of the record review is extensive, additional time to respond to the bulletins is provided by this supplement.
Action to b2 Taken by Licensees and Permit Holders:
This bulletin applies to all power reactor facilities with an operating license or a construction permit, except those already identified as possibly having atypical weld material.
Responses to the requirements in Bulletins 78-12 and 12A shall be submitted in writing in accordance with the folloaing schedule:
1.
Generic reports from each reactor vee:a1 manufacturer shall he submitted to the NRC by May 1, 1979, 2.
The licensee responses shall be submitted by May 29, 1979. The licensee's r,eponse sha1.1 include all of the specific vessel information required by the bulletins which is not covered by the vessel manufaqrurers g2neric report and shall indicate that the licensee is satisfied that the generic report adequately represents data for the specific vessels covered by the licensee's report.
Approved by GAO, B180225 (R0072); clearance expires 7/31/80. Approval was given under a blanket clearance specifically for identified generic
