Statement of Violation

During an NRC inspection conducted October 13 through November 23,1996, a violation

of NRC requirements was identified. In accordance with the " General Statement of

Policy and Procedures for NRC Enforcement Actions," (60 FR 34381; June 30,1995) the

violation is listed below:

Callaway Plant Technical Specification 6.8.1 states, in part, that written procedures

shall be established, implemented, and maintained covering the applicable procedures

recommended in Appendix A ofRegulatory Guide 1.33, Revision 2, February 1978.

Regulatory Guide 1.33, Appendix A 3.e requires, in part, that procedures be written

for component cooling water system startup, operation, and shutdown.

Normal Operating Procedure OTN-EG-1, Revision 14, "C omponent Cooling

Water," was written to provide the appropriate operating instructions for the

component coolir.g water system. Step 2.7 of this procedure stated that, during

, normal operation, the maximum component cooling water flow should not exceed

110 percent of the flow listed in Attachment I of the procedure.

Contrary to the above, the NRC inspectors observed that Procedure OTN-EG-1 did

not give appropriate instructions for proper system operation. Attachment 1 of the

procedure listed minimum flow values only and not a range of flow rates. In addition,

the procedure did not identify minimum system temperature and did not provide

guidance on maintaining proper system temperature. The procedure was unclear as

to the required flow rates to the various components (483/96011-01).

This is a Severity Level IV Violation (Supplement I).

Reason for the Violation

Development and review of Normal Operating Procedure OTN-EG-00001 had primarily

focused on ensuring the Component Cooling Water System was capable of providing

sufficient cooling to perfonn its design basis function. The reviews had not explicitly

evaluated concerns of excessive cooling during cold weather operation.

Corrective Steps Taken and Results Achieved:

The Component Cooling Water (CCW) System wn adjusted to restore flow to the proper

limits. A corrective action document, SOS 96-1795, was initiated on November 14,1996

to address the concerns identified by the NRC ' Resident Inspector. Based on an

engineering evaluation, the FSAR was revised to indicate an allowed minimum CCW

System temperature of 40 F. Revision 15 of OTN-EG-00001 incorporated the FSAR

change and was issued on November 21,1996.

Corrective Stens to Avoid Further Viciations:

On November 24,1996, Quality Assurance commenced a review of the FSAR for CCW

System operating parameters. This review was requested by Nuclear Engineering as a

result of SOS 96-1795 which identified that the minimum temperature for CCW System

operation described in the FSAR had not been captured as an operating parameter in any

3

plant procedures. The Quality Assurance review identified some minor discrepancies in

l

j the normal operating procedures of the CCV.' system but concluded that the emergency

l operating procedures for the system were generally consistent with the system description i

and design parameters included in the FSAR. These findings were published in Quality

Assurance Surveillance Report SP96-103 dated December 18,1996. FSAR Change i

< Notice 96-075 was subsequently initiated December 26,1996 to more accurately describe

the operation of the CCW System. After processing the change notice, Operations will

revise OTN-EG-00001 and the Operator Logs to ensure the CCW System design

-

parameters for flow and temperature are properly maintained.

, Union Electric is also evaluating the concerns identified by this violation for potential

. generic applicability to other systems. Our response to the NRC's 10CFR50.54(f) letter,

dated October 9,1996, will address whether additional actions are required.

Date when Full Compliance will be Achieved:

Full compliance will by achieved by February 7,1997. Further evaluation of potential

generic concerns will be described in our response to the 10CFR50.54(f) letter.
