Results of gamma activity traverses made in process tube channels and VSR channels at 105-KW
Activity traverses were made at Hanford reactor 105-KW in VSR channels 23, 29, 37, 46, 55, 63 and 69 and in process channels 4669, 4569, 4668, 4670 and 4769. These traverses were made during cleaning operations to assist in the location of any contaminated material in these channels and again after completion of the cleaning operations to determine if all of the contaminated material was removed. Upon completion of the cleaning of the VSR channels and process channels activity traverses were made in all of the channels. The results of these traverses show that no detectable amounts of contaminated material were present in any of these channels. The traverses made in the VSR channels all show a large peak in the lower part of the pile indicating that the metal in the lower part of the pile received as much as five times the integrated exposure received by the metal in the upper half of the pile. 15 figs.
