CONSIDERATION DETERMINATION. AND OPPORTUNITY FOR A HEARING l
~
The U.S. Nuclear Regulatory Commission (the Commission)is considering issuance of an amendment to Facility Operating License No. DPR-77 issued to the Tennesme Valley Authority (TVA, the licensee) for operation of the Sequoyah Nuclear Plant, Unit 1, located in Soddy Daisy, Tennessee.
The proposed amendment would add a one-time allowance through operating Cycle 9 to Technical Specification (TS) Surveillance Requirement (SR) 4.4.3.2.1.b to perform stroke
. testing of the power-operated relief valves (PORVs) in Mode 5 rather than Mode 4, as currently required.
Befo(e issuance of the proposed license amendment, the Commission will have made findings required by the Atomic Energy Act of 1954, as amended (the Act) and the '
Commission's regulations.
f The Commission has made a proposed determination that the amendment request involves no significant hazards consideration. Under the Commission's regulations in 10 CFR 9712010321 971124 PDR ADOCK 05000327 P
--e.
,m..-...-
._u,
2 50.92, this means that operation of the facilitp in accordance with the proposed amendment would not (1) involve a significant increase in the probability or consequences of an accident previously evaluated. or (2) create the possibility of a new or different kind of accident from any
\\
accident previously evaluated; or (3) involve a significant reduction in a margin of safety. As required by 10 CFR 50.91(a), the licensee has provided Ms analysis of the issue of no significant hazards consideration, which is presented below:
TVA has concluded that operation of SQN Unit 1 in accordance with the proposed change to the TSs... does not involve a significant hazards consideration. TVA's conclusion is based on its evaluation, in accordance with 10 CFR 50.91(a)(1), of the three standards set forth in 10 CFR 50.92(c).
A. TM proposed amendment does not involve a signPant increase in the probability or consequences of an accident previously evaluated.
The possibility of occurrance or the consequences for an accident or malfunction of equipment is not increased as the PORVs have been tested under representative conditions and are fully functienal. As such, the PORVs are expected to open and close on demand. In addition, the block valves are still available to mitigate flow from the PORVs.
- 8. The proposed amendment does not create the possibility of a new or different kind of accident from any accident previously evaluated.
A possibility for an accident or malfunction of a different type than any evaluated previously in the safsty analysis report may be created; or the possibility for an accident or malfunction of a different type does not exist as the PORVs have been tested under representative conditions and are fully functional. No new failure modes have been introduced.
C. The proposed amendment does not involve a significant reduction in a margin of safety.
The margin of sefety has not been reduced. The PORVs are fully functional.
However, lite.at compliance with the TS requires the block valves to be closed. The margin of safety will be increased if continued operation is allowed with the block y
valves opan.

3 The NRC staff has reviewed the licensee's analysis and, based on this review, it appears that the three_ standards of 10 CFR 50.92(c) are satisfied. Therefore, the NRC staff proposes to determine that the amendment request involves no sigaificant hazards consideration.
- The Commission is seeking public comments'on this propcied determination. Any comments received wiSA 30 days after the date of publication of t' 's nots will be considered in making any final determination.
Normally, the Commission will not issue the amendment until the expiration of the 30-day notice period. Howsver, should circumstances change during the notice period such that failure to act in a timely way would result, for example, !n dorating or shutdown of the facility, the Commission may issue the license amendment before the expiration of the 30-day notice period, provided that its final determination is that the amendment involves no significent hazards consideration. The final determination will consider all public and State comments received. Should the Commission take this action, it will publish in the FEDERAL REGISTER a notice of issuance and provide for opportunity for a hearing after issuar,a. The Commission expects that the need to take this action will occur very infrequently.
Written comments may be submitted by mail to the Chief, Rules Review and Directives Branch, Division of Freedom of information and Publistions A rvices, Office of Administration, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001, and should cite the publication date and page number of this FEDERAL REGISTER notice.
