e APPENDIX A NOTICE OF VIOLATION Niagara Mohawk Power Corporation Nine Mile Point Nuclear Station Unit 1
Docket No. 50-220 License No.
DPR-63 As a result of the inspection conducted on June 16-20,
- 1986, and in accordance with the NRC Enforcement Policy (10 CFR 2, Appendix C), the following violation was identified:
Technical Specification 6.8. 1 requires that written procedures shall be established, implemented and maintained that meet or exceed the require-ments and recommendations of Sections
- 5. 1 and 5.3 of ANSI N18.7-1972 and Appendix A of USNRC Regulatory Guide 1.33.
ANSI N18.7-1972 states that modifications shall be designed and performed in accordance with applicable codes.
Niagara Mohawk Procedure Number NI-ISI-HYD-94 states that the hydrostatic testing for the hydrogen water chemistry sampling line modification will be performed in accordance with ASME Section III, Class NC, 1980 Edition with the Summer 1982 Addenda.
ASME Section III, Class NC, 1980 Edition, Summer 1982 Addenda requires that all pressure retaining components, appurtenances and completed systems shall be pressure tested after work is completed and prior to initial component or system operation.
Chicago Bridge and Iron (CB8 I) Traveler RSL-1 was implemented to control the installation of a modification to a containment penetration to support installation of an incore hydrogen water chemistry sampling system.
Contra'ry to the above, the CBKI Traveler RSL-1 was found to be inadequate because it permitted an installation sequence which violated the require-ments of the ASME Code.
Specifically, in accordance with the Traveler, on June 13,
- 1986, the hydrogen water chemistry system incore sample line was hydrostatic pressure
- tested, and on June 14, 1986 welding was per-formed on the system.
Subsequent to the welding and with no further hydrostatic testing, the system was placed into operation.
This is a Severity Level IV violation.
(Supplement I)
Pursuant to the provisions of 10 CFR 2.201, Niagara Mohawk Power Corporation is hereby required to submit to.this office within twenty 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.
