A low-level radioactive waste performance assessment methodology was developed by Sandia National Laboratories for use by the US Nuclear Regulatory Commission in evaluating license applications under 10 CFR Part 61. The purpose of the methodology is to allow confirmation of a licensee's evaluation of postclosure impacts, to provide reasonable assurance that the performance objectives in 10 CFR Part 61.41 are met. Subsequent work has been undertaken to update and improve the methodology where necessary, and to build confidence in the models in the methodology. Since developing the methodology, it has been applied several times to test cases. This additional experience allows an improved assessment of the modeling needs. This paper assesses the adequacy of the current models, and identifies additional models that may be useful to include in the methodology. Models that have become available since the preparation of the original methodology are discussed. In addition, a formal process for low-level waste performance assessment and treatment of uncertainty is recommended, and model validation is examined.
