Criticality safety considerations for low-level-waste facilities
- Oak Ridge National Lab., TN (United States)
The nuclear criticality safety for handling and burial of certain special nuclear materials (SNM) at low-level-waste (LLW) facilities is licensed by the U.S. Nuclear Regulatory Commission (NRC). Recently, Oak Ridge National Laboratory staff assisted the NRC Office of Nuclear Material Safety and Safeguards, Low-Level-Waste and Decommissioning Projects Branch, in developing technical specifications for the nuclear criticality safety of {sup 235}U and {sup 239}Pu in LLW facilities. This assistance resulted in a set of nuclear criticality, safety criteria that can be uniformly applied to the review of LLW package burial facility license applications. These criteria were developed through the coupling of the historic surface-density criterion with current computational techniques to establish safety criteria considering SNM material form and reflector influences. This paper presents a summary of the approach used to establish and to apply the criteria to the licensing review process.
