1.0 INTRODUCTION

By letter dated January 27, 1986, with modifications and clarifications submitted July 10, 1986, the Georgia Power Company (Georgia Power, the licensee) requested changes to the Hatch 1 & 2 Radiological Effluent i

Technical Specifications (RETS) as incorporated in Facility Operating Licenses DPR-57 and NPF-5.

i 2.0 EVALUATION License Amendment Nos. 110 and 48 to Facility Operating Licenses DPR-57 i

and NPF-5 for the Hatch Nuclear Plant Units 1 & 2 were issued June 28, i

1985. The amendments authorized the incorporation of the RETS into the j

Hatch 1 & 2 Technical Specifications (TS). The RETS were implemented by the licensee on July 28, 1985.

The proposed changes are consistent with NUREG-0473, " Standard Radiological Effluent Technical Specifications for BWRs", Revision 2, l

February 1,1980 (model RETS) and would revise tabular notations for l

gaseous effluent sampling and analysis comitments. Specifically, the proposed changes call for additional sampling following shutdown, startup, or power level changes greater than 15% of rated thermal power

1) to be required only if the primary coolant activity of I-131 and the noble gas activity had increased by more than a factor of 3, and 2) to be followed by analysis of only the principal gama emitters.

During the course of reviewing and implementing the RETS for operating reactors it became evident that the mode of operation of some power reactors would require additional sampling of gaseous effluents, almost continually, if the wording of the earlier RETS guidance were used, t

namely, "following each start-up, shut-down, and thennal power change i

exceeding 15% in one hour". Since the purpose of such additional sampling)is to detect possible rapid releases of radioiodine (" iodine spiking" during significant changes in power, the augmented sampling is l

not necessary unless other monitoring indicators show possible problems i

with failed fuel. Therefore, a revision was made to the RETS guidance adding the caveat that the additional sampling and analysis should be r

done only if the iodine-131 activity in the primary coolant and the noble i

gas activity monitor reading increase by more than a factor of 3 during the power change. The first change proposed by the licensee, namely the i

notation for the additional sampling of gaseous effluents, follows the l

present revised RETS ouidance. Hence, this change is acceptable.

. The second change requested involves clarification of the extent of analysis required for the special samples obtained under the circumstances described above. The format of the tabular comitments of the RETS of the licensee requires analyses of the special gaseous effluent samples for tritium as well as for principal gama emitters.

Since, as explained above, the primary purpose of these samples is to detect an "fodine spike", analysis of tritium is not necessary or pertinent. Hence, the modification of the tabular notation to specify analysis for only principal gama emitters meets the intent of the guidance of the model RETS and, therefore, is acceptable.

3.0 ENVIRONMENTAL CONSIDERATION

This amendment involves a change to a requirement with respect to the installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and/or changes to the surveillance requirements. The staff has determined that the amendment involves 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 Comission, has previously issued a proposed finding that this amendment involves no significant hazards consideration and there has been no public comment on such finding. Accordingly, this amendment meets 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 nor environmental assessment need be prepared in connection with the issuance of this amendment.

4.0 CONCLUSION

The staff has concluded, on the basis of 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, and (2) such activities will be conducted in compliance with the Comission's regulations and the issuance of this amendment will not be inimical to the comon defense and security nor to the health and safety of the public.
