APPENDIX A
"
Public Service Company of New Hampshire Docket No.
50-443
Seabrook Unit 1 License No. CPPR-135 I
As a result of the inspection conducted on July 8 - August 27,1985 and in accordance with the NRC Enforcement Policy (10 CFR 2, Appendix C) published -in the Federal Register on March 8,1984 (49 FR 8583) the following violations were identified:
.
i i
A.
10CFR50, Appendix B, Criterion III and the Seabrook Station FSAR, Section
'
17.1.'1.3 require that the suitability of-materials and processes essential to the safety-related functions of components be reviewed and that deviations.
>
'from the appropriate quality) standards be controlled. Procedure, ASP-3 (Revision 2 New Hampshire Yankee
'
conformance report (NCR)' dispositions are used as design changes, to include
providing design details appropriate _to the identified nonconforming conditions.
i UE&C NCRs 74/1903B and 74/29148 specify repair dispositions to the limit switch j
supports on three safety-related, safety injection (SI) valves.
{
Contrary to the above, as of July. 19,1985, repair work was completed to the three subject, safety-related valve limit switch supports (1-SI-V89, V90, &
I i
V93) using design details,as specified by NCRs 74/19038 and 74/2914B, which
.
were inappropriate to the identified nonconforming conditions and which were unclear as-to specifying the controls and standards necessary to assure the ability ~of the affected components to perfonn their safety-related functions.
This lack of design change clarity resulted in the installation of material
.
and welds in conflict with engineering intent and in the failure to apply the
'
required quality assurance controls, including inspection, to safety-related j
work activities.
l This is a Severity Level IV Violation (Supplement II)'.
,
!
.
i B.
10CFR50, Appendix B, Criterion XVI and the Seabrook Station FSAR, Section
,
l 17.1.1.16 require that conditions adverse to quality be corrected.
In the
'
!
case of significant conditions adverse to quality, particularly those governed
!
by 10CFR50.55(e) requirements, the corrective measures prescribe that the actions
taken be documented and reported, as appropriate.
Seabrook Project Policy No.27 (Revision 3) specifies that in the reporting of 10CFR50.55(e) information,.
'
i corrective action is verified to have been completed by the Construction QA-organization prior to the issuance of a Final Report to'the NRC. For a re-
portable 10CFR50.55(e) deficiency on the diesel generator exhaust silencer
!
pedestal cracking, corrective action was specified to ~be the redesign and i
replacemer.t of' the original concrete pedestals with steel pedestals. The l
Final Report to the NRC, dated June 10,1985, stated that.the redesign and
l rework had been completed.
'
l Contrary to the above, as of July 8,1985, corrective action to the subject l
deficiency on the diesel generator exhaust silencer pedestal cracking had not been completed prior to the issuance of the Final Report to the NRC. Construc-
tion QA verification, in accordance with Project Policy No.27, was inadequately

applied by relying only on documentation, in lieu of hardware, verification.
The QA program for corrective measures was also inadequate, for this case, in
.
not requiring that all safety-related work activities be examined and documented
!
in accordance with quality control acceptance criteria. These inadequacies
!
led to incomplete and unverified bolting work on the steel replacement pedestals at a time when QA docunentation and the June 10,1985 Final Report
.
indicated the corrective action rework had been completed.
,
This is a Severity Level IV Violation (Supplement II).
Pursuant to the provisions of 10 CFR 2.201, Public Service Company of New Hampshire
,
is hereby required to submit to this office within 30 days of the date of the
'
letter transmitting this Notice, a written statement or explanation in reply,
!
including for each violation:
(1) the corrective steps which have been taken and the results achieved; (2) the corrective steps which will be taken to avoid further j
violations; and (3) the date when full compliance will be achieved. Where good cause is shown, consideration will be given to extending the response time.
