4 APPENDlX A NOTICE OF VIOLATIONS PECO Energy Company Docket No. 50-277/278 Peach Bottom Atomic Power Station Unit 2 and 3 License No. DPR-44 I-Delta, PA DPR-56 During an NRC inspection conducted between March 8 and May 3,1997, violations of i
NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions, "10 CFR Part 2, Appendix C (1996), the l
violations are listed below:
A.
10 CFR 50 Appendix B, Criterion Ill, Design Control, requires, in part, that measures be established to assure that deviations from design quality standards for safety-related systems are controlled, t
Contrary to the above, between March 21 and March 26,1997, PECO failed to maintain measures to assure that deviations from the design quality standard for the j
safety-related residual heat removal, high pressure coolant injection, and high pressure service ~ water systems were controlled, Specifically, PECO maintenance j
i personnel constructed scaffolding that was in contact with or within close proximity to components in these safety-related systems without prior evaluation and approval of PECO engineering.
1 B.
Peach Bottom Atomic Power Station, Unit 3, Technical Specifications 3.3.2.2, "Feedwater and Main Turbine High Water Level Trip Instrumentation," requires that if two channels of this instrumentation are not operable with reactor power 2 25%,
that reactor power.be reduced to < 25 % power within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
Contrary to the above, between April 4 and April 14,1997, two channels of the feedwater high water level trip for the C reactor feed pump were not operable and power was not reduced to < 25% within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. Specifically, due to a blown fuse, the C reactor feedpump trip logic was de-energized and unable to cause the pump to trip on a high level. The main turbine trip function and the trip functions on the two other reactor feed pumps remained operable.
These are Severity Level IV violr,tions (Supplement 1).
