A SUGGESTED METHOD FOR CALCULATING THE DIFFUSION OF RADIOACTIVE RARE GAS FISSION PRODUCTS FROM UO2 FUEL ELEMENTS AND A DISCUSSION OF PROPOSED IN-REACTOR EXPERIMENTS THAT MAY BE USED TO TEST ITS VALIDITY

摘要

The calculations reported in CRDC-721 regarding the diffusion of stable rare-gas fission products from UO2 fuel elements have been extended to apply to the radioactive isotopes also. Two proposed in-reactor experiments, in which the rate of release of short lived radioactive xenon and krypton isotopes will be measured during the irradiation of test fuel elements, may be used to test the hypothesis on which the calculations are based.
