To demonstrate compliance with the performance objectives governing protection of the general population in 10 CFR 61.41, applicants for land disposal of low-level radioactive waste are required to conduct a pathways analysis, or quantitative evaluation of radionuclide release, transport through environmental media, and dose to man. The Nuclear Regulatory Commission staff defined a strategy and initiated a project at Sandia National Laboratories to develop a methodology for independently evaluating an applicant's analysis of postclosure performance. This performance assessment methodology was developed in five stages: identification of environmental pathways, ranking the significance of the pathways, identification and integration of models for pathway analyses, identification and selection of computer codes and techniques for the methodology, and implementation of the codes and documentation of the methodology. This paper summarizes the NRC approach for conducting evaluations of license applications for low-level radioactive waste facilities. 23 refs.
