Brief description of amendment: The amendment modifies the Technical Specifications to provide additional and revised trip setpoints that reflect design modifications to reduce containment loads from plant transients. The Technical Specification changes (1) lower the opening and closing setpoints for actuation of four safety relief valves following initial actuation of any one of the four valves, and (2) lower the main steam isolation valve water level trip setpoint.

It also modifies the Technical Specifications to reflect changes to the core design for the third fuel reload of Unit No. 2.

1 Date of Issuance: June 29,1983 Effective Date: June 29,1983 Amendment No.: 33 Facility Operating License No.: NPF-5 Amendment revised the Technical Specifications.

Date of initial notice in Federal Register: May 18,1983, 48 FR 22389.

This Notice stated that we proposed a no significant hazards consideration determination for the licensee's March 30, 1983 amendment request concerning the cycle 4 fuel reload for Hatch Unit 2.

Supplemental letters related to this amendment request dated May 10, May 20, and May 26,1983, were received after issuance of Notica, and were, therefore, not considered 1

in the Notice. However, none of these supplemental letters affect our j

proposed determination as stated in the notice for the following reasons:

(1) our proposed determination that the reload amendment does not involve a significant hazards consideration was made on the basis that (a) the fuel elements for Cycle 4 that are different from elements previously f

approved for Hatch Unit 2 are of a design previously reviewed and approved l

for Hatch Unit 1, and (b) Hatch Unit 1 has operating characteristics that

)

l are not significantly different from Hatch Unit 2; and (2) the informa-1 tion submitted in the supplemental letters simply provided clarifying information related to fuel burnup and fuel corrosion failure considerations and additional Technical Specifications supporting the proposed Minimum

(

Critical Power Ratio limits.

l The Commission's related evaluation of the amendment is contained in a Safety Evaluation dated l

No significant hazards consideration comments received: No.
