The Environmental Protection Agency (EPA) has issued a draft standard (40CFR191) which specifies permissible radionuclide release limits from a repository for high-level waste to the accessible environment. The US Nuclear Regulatory Commission (NRC) has published a proposed rule (10CFR60) which specifies technical criteria for geologic disposal of high-level waste designed to facilitate compliance with the EPA draft standard. This paper presents preliminary results and observations of evaluating the effect of the 10CFR60 numerical technical criteria on reducing the risk and/or uncertainties associated with meeting the EPA draft standard. The impacts of the following three numerical technical criteria were examined: (1) waste package containment of at least 1000 years; (2) control release rate of at most 10/sup -5/ part/year from the underground facility; and (3) groundwater travel time of at least 1000 years to the accessible environment. The analysis consists of three sets of parametric calculations: (1) generic parametric analysis; (2) parametric analysis including geochemical retardation for basalt; and (3) parametric analysis for a hypothetical basalt site.
