1 REPLY TO A NOTICE OF VIOI.ATION a
Violation:
During NRC inspection from April 23 - May 27, 1991, a violation of NRC requirements was identified.
In accord m with the " General Statement of Policy and Procedure for NRC Enforcement Actions, i
'R Part 2, Appendix C, that violation is cited below:
Technical Specification 3.6.3 requires that inoperable containment isolation valves be isolated from each affected penetration by use of at least one deactivated automatic valve which is secured in the isolation position.
Contrary to the above between April 5-16, 1991, Containment isolation Valve SI-V61 wza inoperable but not isolated from each affected penetration by use of at least one deactivated automatic valve secured in the isolation position.
This is a Severity Level IV violation (Supplement I).
Resoonse:
New Hampshite Yankee (NH'J) has determined that the cause of this violation was an inadequate piocedure. Proce dure OS1005.05, S1 System Operation, was inadequate in that it did not identify valve SI-V61 as a normally locked closed valve. A contributing factor to this violation was the failure of the auxiliary operator to notify the control room that the valve being manipulated, SI-V61, was a locked valve. Consequently, on April 5,1991 the control room operator did not recognize that a lacked valve was out of positic.n and therefore failed to verify SI-V61 cload as required by Procedure OS1005.05. He also did not realize that the Limiting Condition for Operation requirements for Technical Specificadon 3f.3, Containment Isolation Valves, were not satisfied.
Upon discovery that SI-V61 was open on April 16, 1991, it was immediately locked closed. New Hampshire Yankee's short term corrective action also included the revision of Procedure OS1005.05 to explicitly identify the requirements to " UNLOCK and OPEN SI-V61" and to " LOCK CLOSED S I-V61."
The explicit identification of these procedural requirements will ensure that NHY's normal practice of notifying the control room operators of the manipulaticn of a locked valve will take place and that such manipulations will be 4
logged. New Hampshire Yankee has also conducted training for its control room personnel regarding proper communication with respect to repositioning locked valves.
New Hampshire Yar.kec's long term corrective actions will include a review of other operating procedures for similar procedural inadequacies. This review and any required procedure revisions will occur during the normal procedure review cycle and will be completed by July 1993.
New H atopshire Yankee will also develop technical guidance addressing the appropriate actions to be taken when manipulating valves (e.g. test, vent and drain valves) within the containment penetration pressure baundary. This action is expected to be completed by July 31, 1991. Additionally, NHY will evaluate the design and location of the pressure instruments downstream of SI-V61 to determine if the locked valve requirement can be eliminated by relocating the instruments or by upgrading their safety classification. This evaluation is being completed during the development of a design change which is expected to be implemented during the second refueling outage.
The actions taken by NHY have resulted in compliance with Technical Specification 3.6.3 on April 16, 1991. Additionally the long term corrective actions described above will ensure continued compliance with this Technical Specification.
