SUBJECT:

COMPLIANCE EVALUATION REPORT: APPLICATION DATED FEBRUARY 28,1997, DEFINITION OF COMPLETION TIMES BACKGROUND By letter dated February 28,1997, the United States Enrichment Corporation (USEC) requested an amendment to the certificate of compliance for the Portsmouth Gaseous Diffusion Plant (PORTS). The request is to include a definition of completion time and to define the maximum interval between repetitive action completion times in the Techn%

Safety Requirements (TSRs) and to revise the appropriate pages in the Safety Analysis Report (SAR).

DISCUSSION l

USEC has proposed to add a definition for completion time to the TSRs and to define the  !

maximum time interval between repetitive action completion times. USEC has proposed a definition for completion times that is consistent with the Westinghouse Standard Technical Specifications (WSTS) (NUREG-1431,1995 version). The completion time definition would become TSR 1.2.7. By adding the definition, USEC is removing any ambiguity as to what is intended when a time frame is provided for a required action upon failure to meet a Limiting Condition for Operation (LCO).

USEC has also proposed a modification to TSR 1.6.2.2e, LCO Completion Times. The [

modification adds a paragraph to the TSR to reflect that if a completion time requires periodic performance, the 25 percent time interval extension applies to each performance after the initial performance. The 25 percent extension already applied to time intervals for consecutive surveillances performed after the first surveillance, however, it was not clear if the extension applied to repetitive actions to be taken upon failure to meet a LCO.

This action is ennsistent with the WSTS. The TSR also makes clear that the time interval extension does not apply for completion times specified as once. This is also consistent with WSTS.

USEC also submitted changes to the SAR to reflect the same items.

l ENVIRONMENTAL REVIEW lssuance of an amendment to Certificate of Compliance GDP-2 to include a new TSR that defines completion times and revises a TSR to define the maximum interval between LCO I action completion times is subject to the categorical exclusion provided in 10 CFR 51.22(c)(19). Therefore, neither an environmental assessment nor an environmental impact statement is required for the proposed action.

CONCLUSION The proposed TSR 1.2.7 defining completion time and the revision to TSR 1.6.2.2e establishing the maximum interval between repetitive LCO action completion times is consistent with the standard practice for the nuclear power industry and is consistent with the language in the Westinghouse Standard Technical Specifications. The staff recommends that the TSR and SAR changes be approved.

The Region ill Inspection staff has no objection to this proposed action.
