t NOTICE OF VIOLATION Monticello Nuclear Generating Station Docket No. 50-263 During an NRC inspection conducted during the period March 29 through May 12, 1988, which reviewed an incident identified by the licensee, a violation of NRC requirements was identified. The violation involved a failure to prepare an adequate procedure.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1986),
the violation is listed below:
Technical Specification 6.5.C.3 states in part:
" Detailed written procedures, including applicable check-off lists and instructions covering areas listed below shall be prepared and followed..... The following maintenance and test procedures will be developed to satisfy routine inspection, preventive maintenance programs, and operating license requirements: preventive or corrective maintenance of plant and systems that could have an effect on nuclear safety."
Contrary to the above, Procedure 7140, Reactor Core Isolation Cooling (RCIC)
System Annual Instrument Maintenance Procedure, was inadequately prepared.
The procedure did not include; a time limit for the closure of RCIC steam line drain isolation valves, and precautions were not included for potential impact of this test procedure on RCIC operability. This resulted in the inoperability of the RCIC system for approximately twenty-two hours on February 8,1988 during performance of this test procedure.
This is a Severity Level IV violation (Supplement I).
Pursuant to the provisions of 10 CFR 2.201, Northern States Power Company 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 reason for the violations if admitted; (2) the corrective steps which have been taken and the results achieved; (3) the corrective steps which will be taken to avoid further violations; and (4) the date when full compliance will be achieved. Where good cause is shown, i
consideration will be given to extending the response time.
