“…The need for computer analyses of isotopic releases has long been recognized, and various methods have been proposed (Schmittroth 1973, Figg and Sanchez 1983, Gross 1980. The code Polyfail (Gross 1980) has been successfully used at EBR-II for some time. Based on Bayesian probability methods, another code, TAFIA, (Figg and Sanchez 1983) was developed for use at the FFTF.…”

The SMTAG computer code is used to identify breached reactor components that have released tag gas. Using measured isotopic cover-gas concentrations, a ranking of the reactor components most likely to have released tag gas is calculated. The code is specifically designed to analyze sequential gas releases that accompany repeated leaks and/or multiple breaches. Other features include age-tagging, analysis of residual background gases, and estimation of fission-product release factors.
