NOTICE OF VIOLATION IES Utilities Inc. Docket No. 50-331 Duane Arnold Energy Center License No. DPR-49 '

During an NRC inspection conducted on September 7 through November 5, 1996, violations of NRC requirements were identified. In accordance with the

" General Statement of Policy and Procedure for NRC Enforcement Actions," the violations are listed below:

l

1. Part 50 of 10 CFR, Appendix B, Criterion V, requires, in part, that activities affecting quality be prescribed by procedures of a type appropriate to the circumstances.

l Duane Arnold Administrative Control Procedure (ACP) 1410.5 ("Tagout  :

Procedure") states, in part, that all DAEC personnel or their supervisor  !

working under a tagout, shall verify the adequacy and safety of the I tagout boundary prior to accepting the tagout and walkdown and  ;

physically inspect the appropriate portion of the tagout boundary prior i to beginning work.

Contrary to the above:

J

a. On September 9, 1996, work instructions for maintenance on the l drywell pneumatic nitrogen compressor was not appropriate for the '

circumstance. The instructions did not ensure that tagouts established an appropriate boundary by. isolating the suction filter prior to beginning work.

b. On September 9, 1996, procedure CKTBKRW120-003, " Westinghouse De-Ion Oil Circuit Treakers Type GM and GMA," Revision 1, was not l appropriate for the circumstance. The procedure lacked sufficient '

detail on the exact location for test equipment hook-ups.

Consequently, a Division II 125 VDC Trouble alarm was received when the test equipment was hooked up incorrectly.

This is a Severity Level IV violation (Supplement 1).

2. Part 50 of 10 CFR, Appendix B, Criterion V, requires, in part, that activities affecting quality be accomplished according to procedures of a type appropriate to the circumstances.

a. Duane Arnold ACP 1410.5 ("Tagout Procedure") states, in part, that the person hanging tags shall place the components in the position -

required by the Components Tagged Form following the sequence specified.

b. Procedure I.E/S-E209-004 (Elger Corp., Reg Transformer 1Y2A and Invertor 1025 Calibration") specified how to hook up DC leads to perform the testing. Additionally, Temporary Document Change Form (DCF) 95-T-0684 provided directions to lift a wire in the ground detection circuit. The wire needed to be lifted to prevent an alarm and possible damage to the inverter from occurring.

l Notice of Violation  ;

i c. Surveillance test Procedure (STP) 42A026-Q ("HPCI Steam Line High j DP Instrument Functional Test / Calibration") directed a relay block

be placed on contacts 1-2 of relay E41-K33.

j Contrary to the above:

! a. On October 8,1996, an operator did not follow the tagout sequence

specified on the tagout sheet and caused a reactor building closed j^ cooling water relief valve for a recirculation sample cooler to i lift. 1

b. On September 25, 1996, I&C technicians failed to hook up leads per procedure I.E/S-E209-004 (Elger Corp., Reg Transformer lY2A and Invertor 1025 Calibration") and failed to incorporate DCF 95-T-0684 into the procedure they were working. Consequently, control l room operators received several instrument AC and Division II 125 VDC Trouble alarms and various components were damaged.

On October 8, 1996, maintenance technicians failed to follow STP c.

42A026-Q and placed the relay block on contacts 11-12. As a result, a Primary Containment Isolation System (PCIS) closure of M02239 (HPCI outboard steam supply isolation valve) occurred. 1 This is a Severity Level IV violation (Supplement 1).

Pursuant to the provisions of 10 CFR 2.201, Duane Arnold Energy Center is hereby required to submit a written statement or explanation to the l U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, i Washington D.C. 20555 with a copy to the U.S. Nuclear Regulatory Commission, Region III, 801 Warrenville Road, Lisle, Illinois 60532-4351, and a copy to the NRC Resident Inspector at the Duane Arnold Energy Center within 30 days of the date of the letter transmitting this Notice of Violation (Notice).
