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 April 6 - May 8, 1981, and in accordance 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... accomplished in accordance with these instructions, procedures, or drawings."
The Seabrook Station PSAR for Units 1 and 2 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."
United Engineers and Cosntructors (UE&C) Specification 9763-IS-1, Re-vision 6, in compliance with 10 CFR 50.55a, indicates that Class 2 piping of the P.esidual Heat Removal (RHR) system shall be examined in accordance with specific requirements of Section XI (article IWC) of the ASME Boiler and Pressure Vessel (B&PV) Code, 1974 edition with addenda thru Summer, 1975. Furthermore, Specification IS-1 states in paragraph.5.2 that:
"The designer shall review the pipe hanger, supports, seismic and pipe whip restraints to assure that this hardware does not interfere with the (in-service inspection) access already provided.
No permanently installed part of any of these attachments shall be closer than 15" to the nearest circumferential weld."
The Summer 1975 addenda to Section XI of the ASME B&PV Code s]ecifies in article IWC-1220 (a) that exemption of components in certain systems from in-service examination requirements is based upon design pressure t
I and temperature considerations.
Contrary to the above, as of April 20, 1981, a piping support for RHR line 158 was being installed in such a location as to interfere with in-service inspection acces:. (closer than 15 inches) of two circum-ferential pipe welds requiring in-service examination. The UE&C design review for this support installation had exempted the line from examination based upon less conservative operating pressure and tempera-ture considerations vice design pressure and temperature.
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, including welding,
... are controlled and

The Seabrook Station PSAR, in paragraph 17.1.9, requires site constructors to control special processes in accordance with the applicable codes, standards, or specification criteria.
UESC Specification 248-43, Revision 5, states in paragraph 2.2.9.5.la.
that:
"Centainment penetration sleeves are classified as parts of the containment liner (ASME B&PV Code, Division 2)."
The applicable edition (1975) of the ASME B&PV Code, Division 2, requires impact testing of the P-No. I base metal weld heat-affected zone for welding procedure qualification of production welding to carbon steel liner material with a nominal section thickness greater than 5/8".
production welding (was Contrary to the above, as of April 24,1981, X15) accomplished to a carben steel containment penetration sleeve of 0.937" thickness using a Welding Procedure Specification (81-III-4 8/1-08-12) not qualified by impact testing in the P-No.1 base metal weld heat-affected zone 2.nd for which the specified maximum qualified thickness had been exceeded.
This is a Severity Level IV violation (Supplement II).
Pursuant to the provisions of 10CFR2.201, Public Service Ccmpany of New Fampshire 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:
