SNRC-1444  ;

l 1

Violation: 10 CFR 50, Appendix J, Section III.C.1 requires that for Type C tests, each valve to be tested be closed by normal operation and without any preliminary exercising.

Contrary to the above, on January 13, 1988, while preparing to leak test RCIC turbine exhaust check valve lE51*08V-0021, the valve was preliminarily exercised in that the test volume was overpressurized

< to greater than 100 psig instead of the required 40 psig test pressure. This occurred as a result of an inadequacy in Procedure SP 84.654.03, Revision 4.

LILCO's Response:

The Long Island Lighting Company acknowledges the occurrence of >

the event. An investigation to determine the cause of the event was initiated and the results concluded that it occurred because insufficient precautions were stipulated in station procedure SP 84.654.03, Rev. 4, "Primary Containment Leak Rate Test".

Engineering has performed an evaluation of this_ event and has determined that this overpressurization (of test pressure, not valve design pressure) would not have damaged the valve. This determination was based on the valve having an ANSI rating of ,

150#,

1. Corrective Steps which Have Been Taken and the Results
Achieved i

A change to station procedure SP 84.654.03 has been approved by the Plant Manager, cautioning against'overpressurizing 4

test volumes utilizing water. The caution statement requires the use of a relief valve in the water supply header and recommends the use of a needle or globe valve to control flow into the test volume.

2. Corrective Steps Which Will Be Taken to Avoid Further Violations The correction of the identified procedural inadequacy by
adding the above mentioned caution statement should prevent recurrence of this event. A revision to the Maintenance I l Section's Training Program, to incorporate the identified procedure change, will be complete by May 31, 1988.
3. The Date When Full Compliance Will Be Achieved

) Full compliance has been achieved.
