. Attachment to ULNRC-3705 January 13,1998 Page1 Seiement of Violation During an NRC inspection conducted on October 26 through December 6,1997, one violation of NRC requirements was identified. In accordance with the " General Statement of Pohey and Procedure for NRC Enforcement Actions," Nl rREG-1600, the violation is listed below:

Technical Specification 6.8.1.a requires, in part, that written procedures shall be established, implemented, and maintained covering the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, February 1978.

Regulatory Guide 1.33, Revision 2, Appendix A, Section 9.a., requires, in part, that maintenance which can affect the performance of safety-related equipment be properly

(

performed in accordance with documented instructions.

Contrary to the above, on October 29,1997, licensee personnel failed to follow documented instructions during a preventive maintenance task to record differential pressure across the essential service water supply and return lines to the Emergency Diesel Generator A engine. Specifically, a temporary differential pressure gauge was left installed for approximately 14.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> aner completion of the preventive maintenance task.

This is a Severity Level IV i.olation (Supplement 1)(50-483/9720-01).

__ eason for the Violation inadequate communication during shift turnover resulted in the Control Room Supenisor understanding that all work had been completed on the creventive Maintenance (PM) task. The Control Room Supervisor understood that a discussion with Nuclear Engineering regarding the test data was the only action still pending. The non-licensed operator had signed ofTthe PM task as field complete. Afler the question regarding the test data was resolved by the ystem Engineer, the Control Room Supenisor signed off the PM task as complete without verifying that the restoration was complete. Note that the auxiliary document for removing the differential pressure gauge was still open and accurately reflected its status. However, the PM task instructions rquired the auxiliary document be completed prior to cornpletion of the PM task.

The relationship between the PM task sheet and the auxiliary document which installed and removed the temporary differential pressure gauge, also contributed to the

a

.Attacivnent to ULNRC-3705 January 13,1998 Page 2 inadequate communication. As written, the documents did not delineate a clear, corv.s work sequence.

Corrective Stens Taken and Results Achieved:

The differential pressure gauge was removed and the system test connections and valves were restored to their normal positions on October 29,1997. A corrective action document was also initiated on that date.

The PM task has been revised to provide a clear, concise work sequence.

This event was also reported as Licensee Event Report 97-011-00 on December 30,1997', in accordance with 10 CFR 50.73(a)(2)(i)(B) as a condition prohibited by Technical Specification.

Correctly Steps to Avoid Further Violations:

This violation resulted from a personnel errer. The concerns identified by this violation have been discussed with appropriate Operations personnel. No programmatic changes are required.

Date when Full Comoliance will be Ach:eved:

Full compliance was achieved by January 5,1998.
