3 A petition for review must be filed with the Secretary of the Commission, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention: lutemakings and Adjudications Staff, or may be delivered to the Commission's Public Document Room, the
- Gelman Building,2120 L Street, NW, Washington, DC, by the above date.
For further details with respect to the action see: (1) the application for amendment and (2) the Commission's Compliance Evaluation Report. These items are avs.bble for public inspection at the Commission's Public Document Room, the Gelman Building, 2120 L Street, NW, Washington, DC, and at the Local Public Document Room.
Date of amendment request: July 30,1997 Brief description of amendment: On July 30,1997, the United States Enrichment Corporation (USEC) requested an amendment to the certificate of compliance for PORTS.
The request is to clarify Technical Safetv Requirement (TSR) 2.1.3.11 dealing with the minimum tes.?. red number of operable smoke detector alarm circuits in the autoclave facilities at PORTS. Responding to an NRC request for additionalinformation, the amendment request was modified by USEC on May 29,1998.
l USEC has proposed to revise the Limiting Condition for Operation (LCO) for TSR 2.1.3.11 from requiring fifty percent of the installed autoclave UF, smoke detection heads to be
! operable to simply requiring the autoclave UF smoke detection systems to be operable. In addition to modifying the LCO, USEC has proposed to clarify TSR 2.1.3.11, Actions Statements, to normally require at least one operable smoke detector alarm circuit to cover t
4 an area above each autoclave in buildings X-342A (Feed Vaporization Facility) and X-344A (Toll Enrichment Services Facility) and above each autoclave pair in building X-343 (Feed Vaporization and Sampling Facility). USEC has also proposed to normally require at least four of the eight detector heads operable at all times in the X-343 facility. This is to alleviate any potential adverse effects on timely detection of a release in the event of winds inside the building when one or both crane doors or hatches are open. Changes were also made to Chapter 3, " Facility and Process Description," of the Safety Analysis Report (SAR).
These changes involve the addition of new sections 3.2.1.1.6, "UF. Leak Detection System" and 3.2.1.2.6, "UF. Leak Detection System," and a new paragraph to section 3.2.1.3.6, "UF. Leakage Detectors." The SAR changes describe the operations and locations of the UF detection systems.
Basis for finding of no significance:
.1. The proposed amendment will not result in a change in the types or significant increase in the amounts of any effluents that may be released offsite.
Clarifying the minimum number of smoke detector alarm circuits required to be operable in autoclave buildings X-342A, X-343, and X-344A will not result in an increase in the amounts of effluents that may be released offsite or result in any impact to the environment.

- 2. The proposed amendment will not result in a significant increase in individual or cumulative occupational radiation exposure.
The proposed clarification of identifying the minimum number of smoke detector alarm circuits required to be operable for autoclave buildings X 342A, X-343, and X-344A will not increase individual or cumulative occupational radiation exposure.
- 3. The proposed amendment will not result in a significant construction impact.
The propos ed changes will not result in any construction, therefore, there will be no construction impacts.
- 4. The proposed amendment will not result in a significant increase in the potential for, or radiological or chemical consequences from, previously analyzed accidents.
The proposed changes which involve clarifying the minimum number of smoke detector alarm circuits required to be operable for autoclave buildings X-342A, X-343, and X-344A will not result in an increase in the potential for UFe releases. The proposed changes will also not result in an increase in the potential for, or radiological consequences from previously evaluated criticality accidents. Therefore, the proposed changes will not result in a significant increase in the potential for, or radiological or chemical consequences from, previously analyzed accidents.

- 5. The proposed amendment will rat result in the possibility of a new or different kind of accident. <
The proposed changes will not result in the possibility of a new or different kind of accident.
- 6. The proposed amendment will not result in a significant reduction in any margin of safety.
The proposed changes, clarifying the minimum number of smoke detector alarm circuits required to be operable in autoclave buildings X-342A, X-343 and X-344A, will not reduce the margin of safety as defined in the Technical Safety Requirement. In fact, an operable smoke detector directly above en autoclave (potential UF release point) would enhance safety by likely providing a more timely detection capability as compared to an operable smoke detector that is not directly above the autoclave.
- 7. The proposed amendment will not result in an overall decrease in the effectiveness of the plant's safety, safeguards, or security programs.
Identifying the minimum number of smoke detector alarm circuits required to be operable in autoclave buildings X-342A, X-343 and X-344A will not result in a decrease in the overall
- effectiveness of the plant's safety program. The staff has also not identified any safeguards or security related implications from the proposed amendment.
