NOTICE OF VIOLATION Commonwealth Edison Company Docket Nos.
50-454; 50-455 Quad Cities Nuclear Power Station License Nos. NPF-37; NPF-66 l
Units 1 and 2 During an NRC inspection conducted on March 7-25, 1994, violations of NRC requirements were identified.
In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C, the violations are listed below:
A.
10 CFR 50.55a.(f)(4)(ii), states, in part, that inservice tests to verify operational readiness of pumps and valves, whose function is required for safety, must comply with the requirements of the latest edition and addenda of the ASME Boiler and Pressure Vessel Code.
1.
ASME Code,Section XI, IWV-3511, " Test Frequency," states that,
" Check valves should be exercised at least once every three months" (quarterly). ASME Code,Section XI, IWV-3522, " Exercising Procedure," states that, " Check valves should be exercised to the position required to fulfill their function...."
Contrary to the above, as of March 25, 1994, the safety functions for the following check valves were not adequately exercised on a quarterly basis:
The open safety function for residual heat removal (RHR) mini flow check valves 1(2)-1001-142A/B/C/D; The closed safety function for service water to control room HVAC supply check valve 1/2-5799-410; The open safety function for high pressure coolant injection (HPCI) system vacuum breaker isolation valves 1(2)-2399-40 and 1(2)-2399-41; The partial open stroke for HPCI system check valves 1(2)-2301-50 and 1(2)-2301-75 as stated in relief request RV-00E; l
The closed safety function for RHR mini flow check valves 1(2)-1001-142A/B/C/D; and j
The open safety function for RHR discharge pump check valves 1(2)-1001-67A/B/C/D.
2.
ASME Code,Section XI, IWV-3411, " Test Frequency," states that,
" Category A and B valves shall be exercised at least once every i
three months" (quarterly). ASME Code,Section XI, IWV-3413,
" Power Operated Valves," states that "the stroke time of all power operated valves shall be measured...."

PDR:_
Contrary to the above, as of March 25, 1994, the open safety function for Category B residual heat removal service water flow control valves 1(2)-1001-5A/5B was not quarterly stroke time tested.
This is a Severity Level IV violation (Supplement I.D.3).
B.
10 CFR 50.55a.(f)(4)(ii), states, in part, that inservice tests to verify operational readiness of pumps and valves, whose function is required for safety, must comply with the requirements of the latest edition and addenda of the ASME Boiler and Pressure Vessel Code. ASME Code,Section XI, IWV-3427, " Corrective Action," Section (a), states that valves with leakage rates exceeding the value set by the owner shall be repaired.
Quad Cities procedure QTS 100-63, " Local Leak Rate Test Procedure for the Standby Liquid Control Check 1(2)-1101-15 and CK 1(2)-1101-16 vaTves," Revision 1, states that immediate corrective action is required when the measured leak rate exceeds the required action range of 10 standard cubic feet per hour (SCFH) for valve 1-1101-16.
Contrary to the above, on November 5, 1992, no immediate corrective actions were taken to repair valve 1-1101-16 when the measured leakage rate (16 SCFH) exceeded the required action range.
This is a Severity Level IV violation (Supplement I.D.3).
Pursuant to the provisions of 10 CFR 2.201, Commonwealth Edison Company is hereby required to submit a written statement or explanation to the U.S.
Nuclear Regulatory Commission, ATTN:
Document Control Desk, Washington, D.C.
20555 with a copy to the Regional Administrator, Region III, and a copy to the NRC Resident Inspector at the facility that is the subject of this Notice, 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 to show cause 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.
Dated at Lisle, Illinois this 28th day of April 1994
