RESRAD drinking water pathway: Probabilistic applications for underground storage tanks

The radioactive wastewater treatment system in place at the Mound plant uses four 129,000-ell (34 000-gal) concrete tanks to collect treated effluent prior to discharge. These effluent tanks are located partially below grade and are therefore components of the plant's active underground storage tank program (AUSTP). In support of AUSTP implementation and evaluation, a screening analysis of the potential radiological consequences of complete failure of these tanks was required. The analysis has been performed and is the subject of this paper
