O APPENDIX A NOTICE OF VIOLATION Public Service Company of New Hampshire Docket No. 50-443 Seabrook Unit 1 License No. CPPR-135 As a result of the inspection conducted March 2 - April 3,1981, and in accord-ance with the Interim Enforcement Policy, 45 FR 66754 (October 7,1980), the following violations were identified:
A.
10 CFR 50, Appendix B, Criterion V states, in part that: " Activities affecting quality shall be prescribed by documented instructions, pro-cedures, or drawings...(which) shall include appropriate quantitative or qualitative criteria..."
The Seabrook Station PSAR states, in.part, in paragraph 17.1.5 that:
"Each organization is required to perfonn their respective quality related activities covered by this program in accordance with documented instructions, procedures, or drawings (which) shall include appro-priate quantitative or qualitative acceptance criteria..."
Contrary to the above, as of March 4, 1981, several UE&C pipe hanger drawings, to include the drawing for hanger 360-RG-24 which had already been field welded, neither provided quantitative details as to the required length of support to embedment weld, nor accounted for approved construction tolerances in the location of the embedments. This lack of appropriate acceptance criteria has resulted in the potential for the erection of inadequate hangers.
s.
This is a Severity Level V Violation (Supplement II).
B.
10 CFR 50, Appendix B, Criterion IX states, in part that: " Measures shall be established to assure that special processes...are controlled and accomplished...using qualified procedures in accordance with appli-cable codes, standards, specifications, criteria, and other special requirements."
The Seabrook Station PSAR, in paragraph 17.1.9, requires site con-structors to control special processes in accordance with the appif-cable codes, standards, or specification criteria.
Perini Field Civil Construction Procedure FCCP-155, Revision 1, governing the Tension Set (TS) bolting process, specifies in para-graph 6.3.1.1 that, "the specified TS Bolts of the proper length" shall be installed. Perini FCCP-155. Ravision 4, governing the welding of structural steel, requires conformance to AWS Standard D1.1-75.

APPENDIX A 2
UE&C Foreign Print FP12086, Revision 5, indicates the connection of l
W18 beams to a structural beam (Cives Mark No. 128498) with 7/8" diameter, high-strength bolts, 2 " long. AWS Standard Dl.1-75 specifies in paragraph 2.8.3 that, "The minimum center to center spacing of plug welds shall be four times the diameter of the hole."
Contrary to the above, as of March 19, 1981, the controlling measures for high-strength TS bolting and AWS welding, to include their final inspection, were inadequate to preclude the following nonconforming conditions on structural beam 12B49B:
Several connections were noted to have been final bolted and accepted with TS bolts having lengths other than 2 ".
Plug welding repair of ten bolt holes in the beam web had been accomplished as directed by the disposition to Perini noncon-fonnance report 1355, with the resultant plug weld spacing much less than the minimum AWS spacing requirements, and without con-sideration of the residual tensile strasses remaining in the beam web as a result of this welding.
This is a Severity Level IV Violation (Supplement II).
Pursuant to the provisiens of 10 CFR 2.201, Public Service Company of New Hampshire is hereby required to submit to this office within twenty-five days of the date of this Notice, a written statement or explanation in reply, including:
(1)the corrective steps which have been taken and the results achieved; (2) corrective steps which will be taken to avoid further violations; (3) the date when full compliance will be achieved. Under the authority of Section 182 of the Atomic Energy Act of 1954, as amended, this response shall be submitted under oath or affirmation.
