A STUDY OF PROBLEMS ASSOCIATED WITH RELEASE OF FISSION PRODUCTS FROM CERAMIC FUELS IN GAS-COOLED REACTORS

PDF Version Also Available for Download.

Description

The diffusion of fission products out of the fuel elements leads to increased shielding requirements, a greater hazard due to their possible release to the surroundings, and more difficult maintenance problems. Continuous processing of the contaminated coolant may alleviate the hazard and maintenance problems; however, extensive in-pile loop experiments are needed for a quantitative evaluation of methods. By proper design of major components such as heat exchangers and blowers, direct maintenance of contaminated equipment may be possible, with or without premaintenance decontamination Such an aporoach is to be preferred to that of providing remote maintenance facilities which, in the case ... continued below
