20555 NRC DOCITT 50-366 OPERATING LICENSE NPF-5 EDWIN I. HA'IGI NUCLEAR PLANT UNIT 2 PIPING REPLACEMENT RADIOIDGICAL CONIBOIS CHANGES Gentimen:
Georgia Power Cmpany letter NED-83-645 dated Decmber 27,
- 1983, provided infomation to NRC concerning radiological controls during replacment of the main recirculation systs piping at Plant Hatch Unit 2.
%e information was provided in response to several specific questions concerning radiological controls raised by the FRC staff following their initial review of our Novmber 7,1983, subnittal which provided details of the piping replacment.
Since the start of the piping replacment, several itms concerning radiological controls have been re-evaluated.
Consquently, we hereby advise you of certain changes in quipnent or methods originally addressed in Attachment 1 to our Dec eber 27, 1983 subnittal. Please be advised that the following changes have ocx:urred since that subnittel was made:
- 1. Water bladders were not used in the suction nozzles f'or shielding as originally planned for Hatch Unit 2 (
Reference:
Deceber 27 subnittal, Attachnent 1, Page 1, Its A, (4), but, were evaluated for use.
%e water bladders were found to be a viable shielding technique for use where dose rates are expected to be higher than those encountered at Hatch Unit 2.
