WASHINGTON. D.C. 20555-0001 June 10, 1993 Docket Nos. 50-321 and 50-366 Mr. W. G. Hairston, Ill Executive Vice President -
Nuclear Operations Georgia Power Company P. C. Box 1295 Birmingham, Alabama 35201
Dear Mr. Hairston:
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION REGARDING NEW 10 CFR PART 20, HATCH NUCLEAR GENERATING PLANT, UNITS 1 AND 2 (TAC NOS. M84730 AND M84731)
The NRC staff is reviewing your application of October 14, 1992, for license amendments to change the Hatch Technical Specifications (TS) to implement revisions to 10 CFR Part 20 as published in the Federal Reaister (56 FR 23360 dated May 21, 1991). Our review includes your letters of December 11, 1992, l
January 15, 1993, and March 26, 1993, that' responded to our previous request' for additional information (RAI). We find that two of your previous responses require further changes or additional information for completion of our
.i review.
Our previous Request 470.3 asked that you revise TS Bases 3/4.15.1.4 (Unit 1),
and 3/4.11.1.4 (Unit 2), " Liquid Holdup Tanks," to use a multiplier of "10 times" for the values of Appendix 8, Table.2, Column 2 to 10 CFR Part 20.1001-20.2401.
Your response proposed to incorporate a multiplier of 10 times, as requested. However, since issuing Request 470.3, the. NRC staff has determined that our request was inappropriate. Accordingly, you should revise your proposed changes to TS Bases 3/4.15.1.4 (Unit 1) and 3/4.11.1.4 (Unit 2) to delete the addition of the words "10 times."
Our previous Request 470.7 asked that you revise your proposed administrative controls in TS 6.12.2, "High Radiation Area," to specify a dose rate range greater than 1000 mrem in 1. hour but less than-500 rads in I hour to distinguish the controls needed for a High Radiation Area from the requirements for a Very High Radiation Area (10 CFR 20.1602).
You responded that TS 6.12.2 conservatively applies access control methods that are
-j applicable to all accessible areas in which radiation levels exceed 1000 mrem per hour, including Very High Radiation Areas, and therefore, that specifying the requested dose rate range is unnecessary. We do'not agree that.the j
controls in existing TS 6.12.2 for the High Radiation Area are conservative or i
adequate with respect to 10 CFR 20.1602.
The access control measures imposed by Hatch's TS at 1000 mrem in I hour are not adequate to meet the " additional measures" required by 10 CFR 20.1602, over those required in 10 CFR 20.1601.
The High Radiation Area TS provides alternate methodology from the " locking" requirement specified in 10 CFR 20.1601 for areas in which an individual might
