? LIC-98-0103 g Page1 REPLY TO A NOTICE OF VIOLATION Omaha Public Power District Docket No.: 50-285 Fort Calhoun Station License No.: DPR-40 During an NRC inspection conducted on May 21 through June 5,1998, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violation is listed below:

10 CFR Part 50, Appendir B, Criterion V, states,in part, that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstance and shall be accomplished in accordance with these instructions, procedures, or drawings.

!

! Standing Order SO-O-1," Conduct of Operations," Revision 36, Step 5.5.3.B, states in part j that the failure of a valve to operate may result in serious consequences; therefore, every i

deficiency must have a maintenance work document written.

Contrary to the above, on May 20,1998, licensee personnel did not write a maintenance work document to document a deficiency with Valve FP-230 following manipulation of the valve. The valve was deficient in that its normal mechanical stop was damaged. This allowed the valve to travel beyond its fully shut position and allowed leakage past its seat.

This is a Severity Level IV violation (Supplement 1)(50-285/9811-01).

Attachment LIC-98-0103 Page 2 OPPD Response 1. Reason for the Violation This special reactive inspection was conducted as a result of the inadvertent deluge of the House Service Transformer, TI A-3. The Root Cause Analysis (RCA) determined that the main cause of the event was a stuck open check valve with the failure to perform preventative maintenance on the deluge valve system as a contributing cause. The failure to initiate a maintenance work request was also identified as a contributing cause in the RCA.

Thi. reason for this violation was Operations personnel failed to initiate a Work Request for an equipment deficiency. The ball valve in question had a bent valve stop, which allowed it to be tumed more than the 90 degrees needed to close the valve. However, no one had initiated a Work Request because they believed it was a minor deficiency.

2. Corrective Steps Taken and Results Achieved a.

Summarized below are the corrective actions described in Licensee Event Report 50-285/1998-005 dated June 19,1998, for the root cause of the failed open check valve, and a contributing cause of failure to perform preventative maintenance.

1) The deluge system for TI A-3 was inspected and repaired, including replacing check valve FP-342 and ball valve FP-230. As a precaution, similar deluge valves have been inspected for similar failure modes.

2) The preventive maintenance actions for the deluge systems will be evaluated and upgraded as required. Additionally, OPPD will complete a review of the preventive maintenance activities for the Fire Protection System to assure that it will operate satisfactorily without inadvertent actuations. This review will be completed by November 20,1998.

b. The Operators involved have been counseled on the proper initiation of a Work Request on deficient equipment, with the exception of one who is on vacation who will be counseled prior to his retum to shift.

c.

A memorandum was issued to all Operators reminding them of proper valve operation and on the need to initiate Work Requests on even minor deficiencies.

Attachment LIC-98-0103 Page 3 3. Corrective Steps That Will Be Taken To Avoid Further Violations This event will be discussed in Operator requalification training to all Operators.

Emphasis will be placed on identifying deficient equipment and writing maintenance work requests for deficient equipment. Training will be completed by September 18, 1998.

4. The date when full compliance will be achieved OPPD is currently in full compliance.
