ATYPICAL WELD MATERIAL IN REACTOR PRESSURE VESSEL WELDS Description of Circumstances:

, j This Bulletin is a supplement to IE Bulletin 78-12, issued on 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 l specified chemical properties in weld; of twelve identified reactor '

, pressure vessels. Use of the atypical weld material in vessel .weldments causes them to have higher than normal all-ductility transition tempera-ture characteristics which in turn requires more consekvative pressure / .

temperature operating limits.

b

! Bulletin 78-12 was issued for the purpose of verifying that similar atypical weld material was not also supplied to other vessel manufacturers 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 modified.

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 atypical weld materiall: '

i l.

Provide all information available on weld materiais used for each reactor vessel primary boundary ferritic weldment.2 (Items lc, ld, '

2a, 2b, first sentence of 2c, 3 and 4 of Bulletin 78-12.) This in-O formation may be provided to NRC through the vessel manufacturers j or suppliers as appropriate to prevent duplication of data. l f .

I 1 The twelve nuclear units identified as havini possible atypical i

pressure vessel weldments are: Three Mile Island Unit Nos. 1 and 2, Crystal River Unit No. 3, Arkansas Nuclear One Unit No.1, Oconee

.  ! Unit No. 3, Rancho Seco Unit No.1, Midland Unit No.1, Quad Cities -

l Unit No. 2, Browns Ferry Unit No.1, Turkey Point Unit No. 4 and j Zion Unit Nos. 1 and 2.

i 2WeldmaterialinformationsubmittedwillbeevaluatedbyMRC. Requests for further information will be dependent upon results of these evalua-tions. Additional requests or instructions will be issued following these evaluations.

.. 2. Correlation of specific heat, lot or batch to specific weldments in

'j specific vessels'is not required at this time. (Last sentence of ij Item 2c,Bulletin 78-12.) However, each licensee is required to a verify that the held materials information provided to the NRC

. z ., ;f under Ite,n 1 does in fact cover each reactor vessel for which the

' '.'- licensee is responsible.

submitted to the Director of the appropriate NRC Regional Office and a copy should be forwarded to the U.S. Nuclear Regulatory 1

Commission, Office of Inspection and Enforcement, Division of

Apprcved by GAO, B'180225 (R0072); clearance expires 7/31/80. Approval
