SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 257 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-57 AND AMENDMENT NO. 201 TO RENEWED FACILITY OPERATING LICENSE NO. NPF-5 SOUTHERN NUCLEAR OPERATING COMPANY, INC.

EDWIN I. HATCH NUCLEAR PLANT, UNIT NOS. 1 AND 2 DOCKET NOS. 50-321 AND 50-366

1.0 INTRODUCTION

By application dated April 29, 2008 to the U.S. Nuclear Regulatory Commission (NRC), Southern Nuclear Operating Company, Inc. (SNC, the licensee), requested changes to the Technical Specifications (TSs) for the Edwin I. Hatch Nuclear Plant, Unit Nos. 1 and 2 (Hatch 1/2).

(Agencywide Documents Access and Management System (ADAMS) Accession No. ML081210467)

The proposed changes would revise TS Figure 3.1.7-1, Sodium Penataborate Solution Volume Versus Concentration Requirements, by implementing an editorial change to improve the readability of the figure.

2.0 EVALUATION The licensee states the following in its application:

LCO [Limiting Condition for Operation] 3.1.7, Standby Liquid Control System, provides the requirements for the Standby Liquid Control (SLC) System. The system consists of a sodium pentaborate solution storage tank, two positive displacement pumps, two explosive valves that are provided in parallel for redundancy, and associated piping and valves used to transfer borated water from the storage tank to the reactor pressure vessel (RPV). The borated solution is discharged near the bottom of the core shroud, where it then mixes with the cooling water rising through the core. A smaller tank containing demineralized water is provided for testing purposes.

The system provides back-up capability for reactivity control independent of normal reactivity control provisions provided by the control rods. The SLC system is used in the event that enough control rods cannot be inserted to accomplish shutdown and cooldown in the normal manner. The system injects borated water into the reactor core to add negative reactivity to compensate for the various reactivity effects that could occur during plant operation. Adherence to Figure 3.1.7-1 of LCO 3.1.7, Sodium Pentaborate Solution

vs. Concentration, ensures that the necessary concentration of borated solution is injected into the reactor vessel.

Recently approved Amendments 247 and 191 to the Units 1 and 2 Technical Specifications revised this plot to increase the required concentration of solution that would be injected into the reactor following an Anticipated Transient Without Scram (ATWS) event. This was necessary to support longer fuel cycles and new fuel designs.

The horizontal axis is labeled with the volume of the solution. The first labeled volume on the horizontal axis is 1000 gallons and then each tic mark represents an additional 200 gallons over the previous mark. Due to the size of the plot, however, one of the tic marks was not labeled. Specifically, the plot goes from 3600 gallons directly to 4000 gallons.

The 3800 gallon tic mark is not labeled.

SNC proposes to enlarge the plot such that all the tic marks can be labeled. Consequently, the new plot presented in this amendment is exactly the same, substantively, as the current Tech Spec plot except that it is larger and each tic mark is labeled.

The changes being made to Technical Specifications Figure 3.1.7-1 are to increase legibility and functionality. The graph is being enlarged to enable labeling all the tic marks on the horizontal axis. These figures were last changed under Amendments 247 and 191 for the Unit 1 and 2 Tech Specs, respectively. The figures remain substantively unchanged. The plotted data is exactly the same as the graph approved under those amendments. Therefore, the ATWS event analysis and SLC system design analyses will not change as a result of this editorial Tech Spec revision.

Increasing the plot size will enhance the labeling of the volume numbers on the horizontal axis, thus making it easier for the operators to read the graph.

The NRC staff reviewed the application and finds the licensees explanation of the basis for the change to be thorough and reasonable, and on the basis that the plotted data is exactly the same as the graph approved under previous amendments to the TS and improved readability of the graph, the NRC staff finds the change to be acceptable.

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the Georgia State official was notified of the proposed issuance of the amendments. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes recordkeeping, reporting, or administrative procedures or requirements.

Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(10). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

The NRC staff has determined that the amendments involve no significant increase in the amounts and no significant change in the types of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure.

The Commission has previously issued a proposed finding that the amendments involve no significant hazards consideration, and there has been no public comment on such finding (73 FR

31723). Accordingly, the amendments meet the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendments.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
