Application of Rapid Fission Gas Analyses to an Off-Gas System Test

Recently developed methods for separation and analysis of radioactive fission gases have been applied to obtain data for an off-gas system of an in-pile loop. A separate in-pile test facility was designed to provide a gas transport stream having fission products having concentrations simulating those anticipated in the off-gas system. Characterization of the radioactivities in this facility provided necessary pre-operational information and specifications for operational and analytical procedures for the off-gas system test.
