Duke Power Company Docket Nos.: 50-413 and 50-414 j Catawba Nuclear Station License Nos.: NPF-35 and NPF-52 Units 1 and 2 EA 97-119 During an NRC inspection conducted on February 10 - 14,1997, violations of NRC requirements were identified. In accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions,"(NUREG 1600), the violations are listed below:

A. 10 CFR 50.65(b) establishes the scoping criteria for selection of safety-related and non-safety related structures, systems, or components to be included within the Maintenance Rule program. Scoping criteria shall include, in part, non-safety related

, structures, systems, or components that are relied upon to mitigate accidents or transients, or are used in the plant emergency operating procedures, or whose failure could prevent safety-related structures, systems, and components from fulfilling their

safety-related function, or whose failure could cause a reactor scram or actuation of a safety-related system.

Catawba Nuclear Station Administrative Procedure, EDM-210, REQUIREMENTS FOR MONITORING THE EFFECTIVENESS OF MAINTENANCE AT THE NUCLEAR POWER PLANTS OR THE MAINTENANCE RULE, Revision 3, implemented the requirements of 10 CFR 50.65(b).

, Contrary to the above, as of February 10,1997, the licensee failed to include a number of structures, systems, and components within the scope of the Maintenance Rule as required. Specifically, the following systems and components were not iricluded withirithe scope of the Maintenance Rule.

i 1. Nuclear Sampling Systems NM-3 and NM-4; and Auxiliary Building Chilled Water System YN-1 (maintains chilled water to the NM sample flow Heat exchanger) - These non-safety related systems were not included in the scope of the Maintenance Rule even though they are relied upon to mitigate accidents or transients.

2. Main Steam to Auxiliary Equipment System SA-3 (maintains steam supply to the three condensate steam air ejectors on each unit) - This non-safety related system was not included in the scope of the Maintenance Rule even though its

. failure could cause a reactor scram or the actuation of a safety-related system.

3. Ice Condenser Hitch Pins 073S (maintains configuration of the ice baAets)-

These non-safety related components were not included in the scope of the Maintenance Rule even though their failure could prevent safety-related structures, systems, and components from fulfilling their safety-related function.
