Commonwealth Edison Company Docket Nos. 50-254; 50-265 l
Quad Cities Nuclear Plant Licenses No. DPR-29; No. DPR-30 Units I and 2 l
During an NRC inspection conducted July 28-30, August 2-4, and August 9-20, 1993, violations of NRC requirements were identified.
In accordance with the-
" General Statement of Policy and Procedure for NRC Enforcement Actions,"
i 10 CFR Part 2, Appendix C, the violations are listed below:
1.
10 CFR 50, Appendix B, Criterion XI states, in part, that all testing required to demonstrate that structures, systems, and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the i
requirements and acceptance limits contained in applicable design documents.
QAP 1500-17, " Post-Maintenance Testing / Verification Procedure",
}
a.
Revision 4, required that post-maintenance tests be specified, performed and documented following maintenance activities.
t Contrary to the above, on April 26, 1993, the licensee failed to specify the required post-maintenance testing associated with nuclear work request #Q99959 (Bus 22 - 4 kV breakers) and testing I
was not performed (254/265-93024-02A(DRS)).
j i
b.
Technical Specification Table 3.2-2, an operation analysis division (OAD) relay setting order, and procedure QC0 ADS 100-1,
" Rock River Division 0AD Undervoltage Relay Calibration." Revision j
0, required a setting of 87 volts 5% (82.65 to 91.35 volts) for the 4kV emergency bus undervoltage relays.
Contrary to the above, as of March 18, 1993, the licensee failed to implement the above design requirements and acceptance limits l
during testing of the 4kV buses 23-1 and 24-1 undervoltage relays.
The calibration data sheets used specified 83 volts 5% (79 to 87
'l volts) (254/265-93024-02B(DRS)).
These violations represent a Severity Level IV problem (Supplement 1).
l 2.
10 CFR 50, Appendix B, Criterion V states that activities affecting
(
quality shall be prescribed by documented instructions or procedures,- of j
a type appropriate to the circumstances -and shall be accomplished in accordance with these instructions or procedures.
l Nuclear Operations Directive (NOD) PP.16, *DC Ground Action l'
Requirements," dated October 1,1989, provided action requirements for plant operation with electrical grounds on safety-related dc systems.

flotice of Violation 2
Contrary to the above, from October 1, 1989, to August 20, 1993, the i
licensee failed to address f400 ground requirements as specified in the f40D and subsequent plant procedures (254/265-93024-03(DRS)).
This is a Severity Level IV violation (Supplement 1).
i 3.
10 CFR 50, Appendix B, Criterion XVI states, in part, measures shall be established to assure that conditions adverse to quality, such as, failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly -identified and corrected.
i a.
Procedure QCAP 2300-6, " Station Commitment and Action Item Tracking," Revision 0, required that operating experience, such I
2 as, General Electric's service information letters (SILs) be evaluated within 90 days.
Contrary to the above, prior to August 20, 1993, the licensee failed to promptly evaluate / identify appropriate corrective.
actions for applicable Sits (254/265-93024-04A(DRS)).

Contrary to the above, from f4ovember 30, 1991, to August 20, 1993, the licensee failed to complete-corrective action inspections _ to identify / replace defective SBli switches on safety-related and i
l important to safety 4kV breakers (25s/265-93024-04B(DRS)).
c.
Contrary to the above, from December 16, 1991, to August 20, 1993, a number of broken / damaged parts were identified that indicated improper handling of safety-related and important to safety 4kV breakers.
Improper handling of 4kV breakers had previously been recorded by licensee personnel, but no corrective action were
-l taken to resolve this condition (254/265-93024-04C(DRS)).
- l These violations represent a Severity Level -IV problem (Supplerent I).
