Technical Specifications item 4.6.l.l.a for a 31-day verification that the valves are closed and locked.Upon'iscovery, a check of the six isolation valves was made and it was found that'll six valves were closed and locked as required.There is no indication that any of the valves have been opened since they were placed in their proper closed position prior to initial criticality of the plant.The cause of the event was personnel error in omitting the six isolation valves from OST-1029 for verification of their locked closed position as required.The immediate corrective action upon discovery was to verify that the six valves were in the closed and locked position as required, which they were.Action to prevent recurrence is that OST-1029 has been revised to include these six valves in the monthly verification of position.NRC Form Sdd This event is being violation of Technical 870'7)280l86 PDR ADOCK reported in accordance with lOCFR50.73(a)(2)(i)(B) as a Specifications Action item 4.6.1.1.a.

OST-1029 has been revised to include the six valves which were omitted from the procedure.

The results of that investigation are as follows'.-

1)1FP-355" In the original design, this valve had an air operator and was closed by a phase A isolation signal.The actuator was deleted by a subsequent change that was not reflected in the flow drawings until the spring of 19S7.Thus, the valve was not included in the early drafts of the procedure.

2)1DW-63" In the initial draft of the procedure, this valve was included but with the incorrect"noun name".It was listed as"Primary Water Supply" vice the real title of"Demineralized Water Makeup".Since Primary Water Supply is not a containment isolation valve, 1DW-63 was deleted from the procedure.

3)1SI-302, 1SI-304, 1CT-103, 1CT"106-The initial draft of the procedure did not include these valve chamber drain valves.The investigation concluded that these valves were omitted because they do not connect directly to containment.

In each case listed, the system valve lineup checklist which is separate from OST-1029 put the valves in the required locked closed position.The root cause of the event is personnel error in omitting the valves in the monthly surveillance test to check their position.~anal sis: Operation of plant components and systems and the health of the general public were unaffected by this event as the valves were in their proper position when checked'.In the case of 1FP-355 and 1DW-63 additional check valves are in series to provide redundant containment isolation capability.

Had the valves'been open during accident'conditions, the potential for additional containment releases to the Reactor Auxiliary Building is minimized.

In the case of the valve chamber drain valves, a chamber does not communicate directly with the containment.

The valve chamber serves to collect and isolate potential leakage from the containment sump isolation valves and from the pipe penetration to the containment sump.If these valves were left open the leakage would be released into the Reactor Auxiliary Building drains or leak-off holdup tanks.Releases into the Reactor Auxiliary Building would either be monitored by area radiation monitors andlor the Plant Vent Stack radiation monitors.This event is reportable in accordance with 10CFR50.73(a)(2)(i)(B) as a violation of Technical Specifications Action Item 4.6.1.1.a.
