Onsite Disposal of Radioactive Waste: Estimating Potential Groundwater Contamination

摘要

Volumes 1 and 2 of the report describe the NRC's methodology for assessing the potential public health and environmental impacts associated with onsite disposal of very low activity radioactive materials. The volume (Vol. 3) describes a general methodology for predicting potential groundwater contamination from onsite disposal. The methodology includes formulating a conceptual model, representing the conceptual model mathematically, estimating conservative parameters, and predicting receptor location. An example case study of shallow burial of waste containing iodine-125 illustrates application of the MOCMOD84 version of the USGS 2-D solute transport model and a corresponding analytical solution. The appendices include a description and listing of MOCMOD84, description of several analytical solution techniques, and a procedure for estimating conservative groundwater velocity values.
