ATYPICAL WELD MATERIAL IN REACTOR PRESSURE VESSEL WELDS Description of Circumstances:
)
This Bulletic is a supplement to IE Bulletin 78-12, issued on i
September 29, 1978, and the two documents should be considered together.
Bulletin 78-12 described the use of weld wire that failed to meet all specified chemical properties in velds of twelve identified reactor pressure vessels. Use of the atypical veld material in vessel veldments csuses them to have higher than normal mil-ductility transition temperature characteristics which in turn requires more conservative pressure / tempera-ture operating limits.
Bulletin 78-12 was issued for the purpose of verifying that similar stypteal veld material was not also supplied to other vessel manufacturers.
J and used in reactor pressure vessel fabrication. Recognizing that the scope of the record review required is extensive and time consuming, and to assure that responses provided are meaningful, the requirements of Bulletin 78-12 are being nodified.

Action To Be Taken By Licensees and Permit Holders:
For all power reactor facilities with an operating license or a

construction permit, except those already identified as possibly having 9 typical veld material.3/

1.
Provide all information available on veld materials used for each reactor vessel primary boundary ferritic weldmentc/ (Items 1c, Id, 2
2a, 2b, first sentence of 2c, 3 and 4 of Bulletin 78-12.) This information may be provided to NRC through the vessel manufacturers or suppliers as appropriate to prevent duplication of. data.
2.
Correlation of specific heat, lot or batch to specific weldments in specific vessels is not required at this time.
(Last sentence of Item 2c,Bulletin 78-12.) However, each licensee is required to verify that the weld materials infornation provided to the NRC under Item 1 does in fact cover each reactor vessel for which the licensee is responsible.
3.
Responses to item 1 above shall be submitted in writing within 120 days of the date of this Bulletin supplement. Reports should be submitted to the Director of the appropriate NRC Regional Office and a copy should be forwarded to the U.S. Nuclear Regulatory Com=ission, Office of Inspection and Enforcement, Division of Reactor Construction Inspection, Washington, D.C.
20555.
Approved by GAO, B180225 (R0072); clearance expires 7/31/80. Approval was given under a blanket clearance specifically for identified generic problems.
d 1'
I 1/ Weld material information submitted will be evaluated by NRC. Requests for further information will be dependent upon results of these evalus-tions. Additional requests or instructions will be issued following these evaluations.
