- Area Code 517 788-0550 March 4, 1980 Mr James G Keppler Off ice of Inspection and Enforcement Region III US Nuclear Regulatory Commission 799 Roosevelt Road Glen Ellyn, IL 60137 DOCKET 50-255 - LICENSE DPR PALISADES PLANT - RESPONSE TO IE BULLETIN 78-08 Consumers Power Company responded to IE Bulletin 78-08 (radiation levels from fuel element transfer tubes) on August 11, 1978.
In that response a commit-ment was made to measure, by remote means during the next refueling outage, radiation levels during the fuel transfer at representative points near the shielding curb.
Measurements were made on October 2, 1979, by placing TLD badges at selected locations (considered to have highest potential for multiple scatter radiation field increase due to fuel transfer) outside containment and inside contain-ment while two spent fuel bundles passed through the transfer tube from the reactor to the spent fuel pool.
The exposure measured by the TLD badges outside containment ranged from 11 to 15 mR during the six hour period which the two bundles passed through the transfer tube.
Inside containment exposure ranged from 47 to 345 mR.
Background radiation contributed significantly to the highest exposure inside containment, due to location of the TLD near primary coolant pump.
It is concluded that the fuel transfer tube shielding effectively precludes any appreciable hazard.
