0 APPENDIX A NOTICE OF VIOLATION Niagara Mohawk Power Corporation Nine Mile Point - Unit 2 License No.
NPF-69 Docket No. 50-410 As a result of the inspection conducted on November 14-18,
- 1988, and in accordance with the "General Statement of Pol.icy and Procedure for NRC Enforcement Actions,"
10 CFR Part 2, Appendix C (Enforcement Policy) (1988),
the following violation was identified:
10 CFR 50 Appendix B Criterion III requires "The design control measures shall provide for verifying or checking the adequacy of design,..."
and Criterion XVII requires "Sufficient records shall be maintained to furnish evidence of activities affecting quality.
The records shall include...
the results of reviews,..."
Con.rary to the above as of November 17, 1988:
Design control measures were inadequate in that they did not identify an incorrect statement in the approved safety evaluation for modification N2Y87MX092, Scram Discharge Vent and Drain Valve Limit
- Switches, which stated "... cables are run in existing conduit" when in fact a
new conduit run was installed; and, for the modification PN2487MX165, Rosemount 1153B transmitters, the control measures did not identify the GE FDDR KG1-6221, Rev.
0 80+5 F temperature requirement for transmitter (calibration) dampening adjustment work.
In addition, the subject work was performed with procedures approved without the 80+5 F temperature requirement being specified.
The records for modification PN2487MX165, Rosemount Transmitters, were inadequate in that there was no documented design analysis record in the modification package to show acceptability of any time delay effects on the reactor coolant system flow signal input to the APRMs.
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Duquesne Light Company is hereby required to submit to this office within thirty days of the date of the letter which transmitted 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; and (3) the date when full compliance will be achieved.
Where good cause is shown, consideration will be given to extending this response time.
