I NOTICE OF VIOLATION Commonwealth Edison Company Docket Nos. 50-237; 50-249 Dresden Nuclear Power Station License Nos. DPR-19; DPR-25 During an NRC inspection conducted from February 28 through April 5, 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:
- 1.
10 CFR Part 50, Appendix B, Criterion Ill, "Design Control," requires verifying and checking the adequacy of design.

Contrary to the above:
Design control measures for controlling modifications Ml2-2-84-119 and Ml2-3-84-119, which were made to the Standby Liquid control system in 1986 and 1987, were not adequate.
The system pressure, after the modifications, was calculated to be 1330 psig, which exceeded the original design pressure by 55 psig. This increased pressure was not addressed.
The hardware was not upgraded and the increase in pressure was not included in specified testing requirements (237/249/94003-0l(DRS)).
This violation represents a Severity Level IV problem (Supplement I).
10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality be accomplished in accordance with documented instructions, procedures, or drawings.

Dresden Operating Procedure DOP 6500-04, "Racking Out 4160 Volt Manually Operated Air Circuit Breaker," required that breakers removed from cubicles be restrained to prevent rolling.
B. & C.
Dresden Administrative Procedure OAP 02-09, "Control of Critical Drawings" required that control room drawings be revised or updated to reflect the correct plant configuration.
Contrary to the above:

B.
On March 10, 1994, the control room copy of drawing 12E-2322B, "Overall key Diagram, 125V DC Distribution Centers, Dresden Nuclear Power Station Units 2 & 3," Revision C, dated July 3, 1991, had not been marked or revised to show the changes made by the installation of partial modification Ml2-3-90-13A as required by OAP 02-09. This partial modification was completed in January of 1993 (249/94003-02B(DRS)).
