m Appendix NOTICE OF VIOLATION Northern States Power Company Docket Nos. 50-282; 50-306 As a result of the inspection conducted on September 17-19, 26, and October 1, 1985, and in accordance with the General Policy and Procedures for NRC Enforcement Actions (10 CFR Part 2, Appendix C), the following violation was identified:

Technical Specification 6.5.A requires that detailed written procedures for plant operations be prepared and followed.

1. Operations procedure for " Isolation and Restoration" for valves and switches involved in maintenance activities provides for identification of items (including valve number) and their respective normal status, isolation status, and verification of return to normal status.

i Contrary to the above, on August 9, 1985, during the process of restoring valves to the normal status in conjunction with Isolation and Restoration Log No. J4061-WL, (following maintenance on No. 122 ADT Monitor Tank pump) valve WL-16-68, a recirculation cross-connect valve between ADT Monitor Tanks No. 121 and No. 122, having a normally closed status was erroneously restored to an open status, due primarily to the failure to have a copy of the isolation and restoration procedure (which identified the normal valve status) in hand.

l

2. Operations release procedures C21.1.5.1, Revision 2,." Releasing No. 121 ADT Monitor Tank to the River," and C21.1.5.2,' Revision 2,

" Releasing Waste From No.122 ADT Monitor Tank to River," in the

section titled " Precautions" state that only one liquid release is to be made at a time and in Step 1.a.6, both procedures specify that valve WL-16-68, on ADT monitor tank pump.

recirculation cross-connect line (between the two ADT monitor l tanks) is to be checked shut prior to the relea:e. Release l instructions PINGP-39, Revision 14, " Liquid Release Instructions,"

(associated with release procedure RP-123) in Part 3 requires signed approval of the Shift Supervisor prior to initiation of i

a liquid release.

l Contrary to the above, on August 15,'1985, a liquid release from No.122 ADT Monitor Tank to. the river was initiated and completed by plant attendants without verifying that valve WL-16-68 in the cross-connect line between No. 121 ADT Monitor Tank and No.122 ADT Monitor Tank was closed. Further, since 8510220003 851010 DR ADOCK 0 p l

e i

\

Appendix 2 the referenced valve was open (had remained open since the improper restoration positioning on August 9, 1985) and No. 121 ADT Monitor Tank pump was in operation for recirculating the water in that tank in preparation for its subsequent release, approximately 2000 gallons of its contents were inadvertently released simultaneously with the release of No. 122 ADT Monitor Tank. Further,.the 2000 gallon inadvertent release was made without required prior signed approval of the shift supervisor.

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

Pursuant to the provisions of 10 CFR 2.201, you are required to submit to this office within thirty days of the date of this Notice a written statement or explanation in reply, including for each item of noncompliance: (1) cor-rective action taken and the results achieved; (2) corrective action to be taken to avoid further nor. compliance; and (3) the date when full compliance will be achieved. Consideration may be given to extending your response time for good cause shown.
