Performance assessment for a below-ground vault low-level radioactive waste disposal facility
- Rogers Associates Engineering Corporation, Salt Lake City, UT (USA)
The U.S. Department of Energy is responsible for assisting in the evaluation of alternative technologies for disposal of low-level radioactive waste (LLW). Part of this effort has included the development of a prototype Safety Analysis Report (SAR) for a below-ground vault (BGV) disposal facility. The SAR has been prepared following guidance provided by the U.S. Nuclear Regulatory Commission (NRC). The objectives of the project were to (a) extend the available body of knowledge on alternative LLW disposal technologies, (b) identify and address potential licensing issues, (c) provide for NRC review and comment, and (d) develop prototype license documentation using NRC guidance. The BGV LLW disposal facility is designed to accomplish all the performance objectives and functional requirements of 10CFR61. The principal design features provided to accomplish these functions include class A vaults, class B/C vaults, disposal unit cover systems, a surface water drainage system, and a percolating water drainage system. The results of this performance assessment show that the doses for all pathways assessed are below the current regulatory limit of 25 mrem/yr. While all possible exposure scenarios and pathways cannot be evaluated, a reasonable comprehensive set of scenarios has been addressed.
