! ENCLOSURE 1 l

l NOTICE OF VIOLATION PECO Energy Docket Nos. 50-352;50-353 l Limerick Generating Station License Nos. NPF-39; NPF-85 Unit 1 and 2 During an NRC inspection conducted between May 19,1998, through July 6,1998, violations of NRC requirements were identified. In accordance with the " General l

Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violations are listed below:

A. Technical Specification 4.6.3.2 requires, in part, that each primary containment isolation valve (PCIV) shall be demonstrated operable at least once per 24 months by verifying that on a containment isolation test signal each automatic isolation valve isolates to its isolation position.

Contrary to the above, since initial plant operation, testing conducted at least once per 24 months to demonstrate the operability of 89 PCIVs, at both units combined, was inadequate, in that, the testing did not verify that each valve isolated to its isolation position on a containment isolation test signal. Specifically, when these valves were tested, the methodology used did not confirm that the valves would close fully, with the thermal overload protection bypassed, thereby creating the potential for leakage past the valve.

This is a Severity Level IV violation (Supplement 1).

B. 10 CFR 50.73 (a) requires the F of an operating license for a nuclear power plant (licensee) shall submit e ' s Event Report (LER) for any event of the type described in this paragraph wt , days after the discovery of the event.

10 CFR 50.73 (a)(2) requires the licensee shall report: (l)(B) any operation or condition prohibited by the plant's Technical Specifications.

Contrary to the above, as of March 4,1998, the licensee had not submitted an LER for a condition prohibited by the plant's Technical Specifications within 30 days after the discovery of the event. Specifically, on February 2,1998,the licensee identified 20 safety related valves that had not been adequately tested in accordance with Technical Specifications 4.6.3.2 and this was not reported in an LER.

This is a Severity Level IV violation (Supplement I).

Enclosure 1 2 Pursuant to the provisions of 10 CFR 2.201, PECO Energy is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN:
