APPENDIX A l
Wolf Creek Nuclear Operating Corporation Docket No.:
50-482 Wolf Creek Generating Station License No.:
NPF-42 i
During an NRC inspection conducted on February 14 through March 27, 1993, a violation of NRC requirements was identified.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violation is listed below-Clearance Order issues i
l Technical Specification 6.8.1.a states that written procedures shall be i
established, implemented, and maintained covering the applicable l
procedures recommended in Appendix A of Regulatory Guide 1.33, Revision 2, dated February 1978.
Regulatory Guide 1.33, Appendix A, Item 1.c, requires administrctive procedures for equipment control (e.g., locking and tagging). This is accomplished, in part, by Procedure ADM 02-100, " Clearance Order Procedure," Revision 27.
Procedure ADM 02-100, Step 7.1.3.4 specified, in part, that, "After the j
clearance and tags have been prepared and approved, the shift i
supervisor / supervising operator shall review the tagging arrangement and verify that the clearance will not adversely affect the plant."
Contrary to the above, two examples of inadequate control and coordination occurred while implementing clearance orders:
(1) On March 11, 1993, without the cognizance of the shift l
supervisor / supervising operator, licensee personnel opened i
Valve EG V221, the excess letdown heat exchanger tube side combined drain valve listed under Clearance Order 93-0435-BG, prior to i
depressurizing the pressurizer relief tank.
This released i
radioactive gas into the containment. When personnel implemented a clearance order change, the personnel inappropriately took both the clearance order and the clearance order change to the field. The tag for Valve BG V221 was not intended to be placed and Valve BG V221 was not intended to be opened until the pressurizer relief tank was depressurized and drained.
(2) On March 21, 1993, with the reactor defueled, because personnel did not place Clearance Orders 93-0618-EJ and 93-0651-EJ in the correct l
order, the reactor coolant system level decreased below the half-pipe level.
Instructions on Clearance Order 93-0651-EJ specified opening listed valves if they are not in conflict with existing clearances to help drain systems.
Prior to placing Clearance Order 93-0651-EJ. personnel failed to assure that no adverse consequences would occur.
This is a Severity Level IV violation.
