1 NOTICE OF VIOLATION Commonwealth Edison Company Docket Nos.
50-254; 50-265 Quad Cities Station, Units 1 and 2 License Nos. DPR-29; DPR-30 During an NRC inspection conducted on June 29 through August 20, 1993, three violations of NRC requirements were identified.
In accordance with the
" General Statement of Policy and Procedure for NRC Enforcement Actions,"
l 10 CFR Part 2, Appendix C (1993), the violations are listed below:
1.
10 CFR 50, Appendix B, Criteria II states, in part, that activities affecting quality shall be accomplished under suitably controlled conditions including adequate cleanness.
Contrary to the above, on July 8,1993, the conditions of ihe high pressure coolant injection (HPCI) and reactor core isolation cooling (RCIC) system pump rooms were not suitably controlled.
Specifically, the HPCI skid had water accumulation in the catch basin, metallic debris (wire and metal tags) were found under the turbine casings, a RCIC turbine had a conduit held up by " duct" tape, small pipe clamps were unattached, a HPCI drain valve gland nut was missing screws, and the rooms were cluttered with various materials left inside the contaminated boundary.
This is a Severity Level IV violation (Supplement 1).
2.
Quad Cities Technical Specification 6.2.A.1 states the applicable procedures recommended in Appendix A of Regulatory Guide 1.33, Revision i
2 dated February 1978, shall be established, implemented, and maintained.
Regulatory Guide 1.33 Appendix A included procedures for plant operation and maintenance.
Quad Cities Offnormal Administrative Procedure (Q0A) 912-1, H-12, Revision I required plant operators to verify at the local panel the cause of the common " control room standby HVAC system minor trouble" alarm and perform subsequent actions based on that determination.
Quad Cities work request (WR) Q07928, dated June 23, 1993, required in the Post Maintenance and/or Test section that a Visual Inspection (VT) be performed on the reactor core isolation cooling (RCIC) system piping.
Contrary to the above:
a.
On June 24, 1993, during electrical bus manipulations, the toxic I
gas analyzer was rendered inoperable for seven hours due to inadequate instructions and a failure to follow the applicable annunciator procedures.

9309300142 930922 PDR ADOCK 05900254 i G
PDR i
b.
On July 20, 1993, a required visual examination by operations personnel for the reactor core isolation cooling (RCIC) rupture disc leakage was not performed as required by Work Request Q07928.
This is a Severity Level IV violation (Supplement 1).
3.
Appendix B of 10 CFR Part 50, Criterion XVI, states in part, measures shall be established to assure that conditions adverse to quality are promptly identified and corrected.
Contrary to the above, corrective actions to improve control over radiological contaminated areas have been inadequate. During the report period, previous corrective actions failed to prevent improper movement of equipment through contaminated areas or control draping of material across contaminated area boundaries.
This is a Severity Level IV violation (Supplement IV).
Pursuant to the provisions of 10 CFR 2.201, Commonwealth Edison is hereby required to submit a written statement of explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington D.C. 20555 with a copy to the U.S. Nuclear Regulatory Commission, Region III, 799 Roosevelt Road, Glen Ellyn, Illinois, 60137, and a copy to the NRC Resident Inspector at the Quad Cities Nuclear Station within 30 days of the date of the letter transmitting this Notice of Violation (Notice). This reply should be clearly marked as a " Reply to a Notice of Violation" and should include for each violation:
(1) the reason for the violation or, if contested, the basis for disputing the violation, (2) the corrective steps that have been taken and the results achieved, (3) the corrective steps that will be taken to avoid further violations, and (4) the date when full compliance will be achieved.
If an adequate reply is not received within the time specified in this Notice, an order or a demand for information may be issued as to why the license should not be modified, suspended, or revoked, or why such other action as may be proper should not be taken. Where good cause is shown, consideration will be given to extending the response time.

EXECUTIVE
SUMMARY
~
Plant Operation i
Although a renewed emphasis on personal accountability was noted, performance in this area declined. Two violations with multiple examples were ' identified.
The first violation concerned the unacceptable condition of the HPCI and RCIC r
pump rooms observed during the report period. The second violation concerned failure to follow and inadequate procedures regarding inoperability of the toxic gas analyzer. Another procedure violation example concerned failure to conduct required post maintenance testing, t
Radioloaical Controls Control of radiological boundaries continued to be of concern.
Instances of items crossing over and cables improperly draped over designated boundaries were identified. One violation for inadequate corrective action was issued.
Through the use of training and equipment mockups, actual person-rem dose for fuel pool demineralizer filter change-outs was reduced from 5 to I rem.
Maintenance and Surveillance t
l During the report period, a failure to perform post maintenance testing on electrical distribution breakers was identified. A breaker malfunction resulted in a unplanned reactor power transient from 28 percent down to 17 percent. A special inspection was conducted to review electrical maintenance activities.
Results of that inspection are documented in Inspection Report 50-254/93024(DRS). An example of a previous violation (50-265/93012-02) regarding failure to perform adequate post modification testing was identified during the inspectors review of HPCI logic problems.
