. - 7590-01 U.S. NUCLEAR REGULATORY COMMISSION NOTICE OF AMENDMENT TO CERTIFICATE OF COMPLlANCE GDP-1 FOR 1HE U.S. ENRICHMENT CORPORATION PADUCAH GASEOUS DIFFUSION PLANT PADUCAH, KENTUCKY DOCKET 70-7001 The Director, Office of Nuclear Material Safety and Safeguards, has made a determiration ; hat the following amendment request is not significant in accordance with 10 CFR 76.45. In making that determination the staff concluded that: (1) there is no change in the types or significant increase in the amounts of any effluents that may be released offsite; (2) there is no significant increase in individual or cumulative occup:tional radiation exposure; (3) there is no significant construction impact; (4) there is no significant increase in the potential for, or radiological or chemical consequences from, previously analyzed accidents; (5) the proposed changes do not result in the possibility of a new or different kind of accident; (6) there is no significant reduction in any margin of safety; and (7) the proposed changes will not result in an overall decrease in the effectiveness of the plant's safety, safeguards or security programs. The basis for this determination for the l amendment request is shown below.

The Nuclear Regulatory Commission staff has reviewed the certificate amendment application and concluded that it provides reasonable assurance of adequate safety, safeguards, and security, and compliance with NRC requirements. Therefore, the Director, Office of Nuclear Materiel Safety and Safeguards,is prepared to issue an amendment to the Certificato of Compliance for the Paducah Gaseous Diffusion Plant. The staff has prepared a Compliance Evaluation Report which provides details of the staff's evaluation, i

2 The NRC staff has determined that this amendment satisfies the criteria for a categorical oxclusion in accordance with 10 CFR 51.22. Therefore, pursuant to 10 CFR 51.22(b), no environmentalimpact statement or environmental assessment need be prepared for this amendment.

U. S. Enrichment Corporation (USEC) or any person whose interest may be affected may file a petition, not exceeding 30 pages, requesting review of the Director's Decision. The petition must be filed with the Commission not later than 15 days after publication of this Eederal flesistm Notice. A petition for review of the Director's Decision shall set forth with particularity the interest of the petitioner and how that interest may be affected by the results of the decision. The petition should specifically explain the reasons why review of the Decision should be permitted with particular reference to the following factors: (1) the interest of the petitioner; (2) how that interest may be affected by the Decision, including the reasons why the petitioner should be permitted a review of the Decision; and (3) the petitioner's areas of concern about the activity that is the subject matter of the Decision.

Any person described in this paragraph (USEC or any person who filed a petition) may file a response to any petition for review, not to exceed 30 pages, within 10 days after filing of the petition. If no petition is received within the designated 15-day period, the Director will issue the final amendment to the Certificate of Compliance without further delay, if a petition for review is received, the decision on the amendment application will become final in 60 days, unless the Commission grants the petition for review or otherwise acts within 60 days after publication of this Federal Reaister Notice.

- A petition for review must be filed with the Secretary, U.S. Nuclear Regulatory __ j Commission, Washington, DC 20555 0001, Attention: Rulemakings 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 re=pect to the action see (1) the application for amendment and (2) the CommiseLn's Compliance Evaluation Report. These items are avails.;le 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.

1 Date of amendment request: April 14,1997, as revised June 13, June 23, and August 18, 1997 Brief description of amendment: The amendment proposes to revise the Technical Safety

- Requirement (TSR) on the cell trip function to provide clarification of battery cell parameters, to provide for ali. '1 ate means of verifying functionality of the cascade cell trip circuit, and to provide a definition of planned and unplanned cell shutdown.

L Basis for finding of no significance:

1 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, il a

- s-- r rw

• mew a m-+---yr- ,- y^w_ y-' a- e w-*e 9-- y

4 The proposed changes will provide an alternative surveillance test to verify the functionality of the cascade cell trip circuit and will provide clarification for battery cell parameters. There are no effluent releases associated with this change, the proposed changes will not affect the effluent.

2. The proposed amendment will not result in a significant increase in individual or cumulative occupational radiation exposure.

The proposed changes do not relate to controls used to minimize occupational radiation exposures, therefore, the changes will not increaso exposure.

3. The proposed amendment will not result in a significant construction impact.

The proposed 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 provide for the clarification of battery parameters and ability to test cell trip function by a second method. This surveillance method can be performed on cells that are shutdown, providing a means to meet the surveillance requirements and restart the shutdown cell. The test is functionally equivalent to the surveillance currently specified in l

1 41. . .

. .- 5 the TSR. .The proposed changes do no represent an increase in the potential for,~or f

radiological or chemical consequences from, previously. evaluated accidents, f

7 5.- The proposed amendment will not result in the possibility of a new or different kind q of accident.

1 The proposed changes to the-TSR do rot result in any situation whereby components are

[

not capable of performing the required safety functions The proposed changes would not create new oper? ting conditions or new plant configuration that could lead to a new or .

different type of accident.

6 The proposed amendment will not result in a significant reduction in any margin of safety.

Although the timing of the surveillance for testing cell trip function is modified by ,

addition of the alterative test, system operability is still ensured before the cellis

- restarted. The other changes to the TSR do not result in any situation whereby the components s

are not capable of performing the required safety function, These changes do not decrease the margins of safety.

. 7. The proposed amendment will not result in an overall decrease in the effectiveness-

. of the plant's safetyi safeguards or security programs. s 4
