RADIATION EFFECTS: APPARATUS FOR IN-PILE ELECTRICAL MEASUREMENTS AND EFFECT OF RADIATION UPON STRAIN GAGE INSULATION COMPONENTS
Abstract
Test facilities were developed for a series of in-pile experiments to be inserted in the reactor core immediately adjacent to the fuel element assembly of the NRL pool-type reactor. The apparatus design includes provision for inpile electrical measurements, in-pool assembly and disassembly of experiments, temporary stor-AGE IN THE POOL AND TRANSFER CAPABILITY FOR POSTIRRADIATION OPERATIONS IN THE HOT CELL. The program of study of the effects of nuclear irradiation upon the components of the ceramic bonded strain gage was continued with evaluation of the electrical resistance of lead wire insulation. The insulation resistance between electrical conductors was maintained at values greater than 10,000 megohms during an exposure to an integrated fast neutron flux. The high values of resistance were obtained with a ceramic-type wire insulation tested in an inert atmosphere of dry helium. (Author)
