Attachment I.
Violation:
Technical Specification 6.8.1 requi res that written procedures shall be established, implemented, and maintained.
(1)
Station. Procedure 108 Equipment Control, step 5.2.17 st a tes,' The RED / WHITE is a mechanical tag and is to be used on mechanical equipment such as va l ves, mechanical
- controls, etc.,
where the operation of such equipment would create a condition unsafe to life or property.
No equipment bearing a RED / WHITE tag shall be operated for any reason whatever.
Contrary to the above, during a plant walkdown performed on November 28, 1987, two containment spray pump suction gauge isolation valves which were tagged shut had their RED / WHITE tags removed and were found to be open.
Response
GPUN concurs with the violation as stated.
The red / white tags had been temporarily removed and the isolation valves opened so that the pump suction pressure could be obtained as part of a scheduled survelliance.
This was done in accordance with Procedure No. 108, "Equipment Control" whereby an operator can remove tags and become the controlling mechanism for the outage as long as he remains continuously present at the tagged components until the tags are rehung or ordered permanently removed.
However, the surveillance was interruped while in progress and the operator failed to rehang the tags when he lef t the area.
Upon identification of this deficiency, immediate action was taken to close the suction pressure gauge isolation valves and rehang the red / white tags.
Full compliance was achieved as of November 30, 1987 The gauges had been isolated and tagged out of service because the seismic mounting of the gauges was under review.
It was discovered as a result of this event that an engineering evaluation had been previcusly completed but not conveyed to the Operations Department and that the mounting satisfied all seismic criteria.
Therefore, the tagout was subsequently cleared and the valves repositioned in accordance with Station Procedure No. 310, "Containment Spray System Operation".

Violation:
Technical ' Specification 6.8.1 requires that written procedures shall be established, implemented, and maintained.
(2)
Station Procedure 310, Containment Spray System Operation, provides detailed instructions for the operation of the containment spray system.
This includes a valve line up of the system in accordance with valve check off list figure 310-1.
This valve check off list prescribes heat exchanger 1-1 and 1-2 pressure indication gauge isolation valves V-3-506, 507, 513 and 514 be open.
Contrary to the above, during a plant walkdown performed on November 28, 1987, these valves were found to be shut.
Response
GPUN concurs with the violation as stated.
The mispositioning of these valves occurred as a result of a surveillance test.
The heat exchanger 1-1 a id 1-2 pressure indication gauge i solation valves V-3-506, 507, 513 and 514 are located on top of their respective heat exchangers in close proximity to the differential pressure gauge i solat ion val /es V-3-435 and 436.
The operator believed that he was to isolate all the gauges on top of the heat exchangers at the completion of the surveillance.
However, only the differential pressure gauges were to be isolated by the surveillance procedure as they were installed as are tempora ry variations which are used for performance monitoring.
The operator failed to consult the surveillan:e procedure and inadvertently shut the pressure gauge isolation valves along with the differential pressure gauge isolation valves.
Immediate corrective action was taken and a valve lineup was performed on these instmment lines in accordance with valve check off list figure 310-1.
These valves were repositioned and independently verified.
Full compliance was achieved as of November 30, 1987 Subseauent to this event, a plant modification was completed and differential pressure gauges were permanently installed.
The temporary variation was removed and the valve lineup checklist was changed to incorporate this modification.
Corrective Actions The following corrective actions will be taken to prevent future recurrence of these items:
(1)
The Operations Department incident critique report for this event will be incorporated into the Required Reading Program for all Operations Department personnel.
Projected Completion Date:
3/31 /88

(2)
Operations Department bianagement shall review this event with all 1
Operations Department personnel and stress the importance of procedural compliance, attention to detail, and proper communications.
Projected Completion Date:
3/31 /88 (3)
The Operations Department shall evaluate the current practice of using operators as a human tagout boundary and if deemed inappropriate, revise Procedure No. 108, Equipment Control" to eliminate this practice.
Projected Completion Date:
6/30/88 l
