Abstract

A research consortium comprised of representatives from several universities and national laboratories has been established as part of this on-going project to generate internal and external dose conversion coefficients for radionuclides produced in spallation neutron sources. Information obtained from this multi-year study will be used to support the siting and licensing of future accelerator-driven nuclear initiatives within the U.S. Department of Energy complex, including the Spallation Neutron Source (SNS) and the Advanced Fuel Cycle Initiative (AFCI) Projects. Determination of these coefficients will also fill data gaps for several hundred radionuclides that exist in Federal Guide Report No. 11 and in Publications 68 and 72 of the International Commission on Radiological Protection (ICRP).

Representatives from the Working Group established in Year 1 have developed and verified a methodology to develop dose coefficients from radionuclides produced during the spallation process. Dose coefficients have been generated using this methodology for a select few radionuclides. Personnel built on the progress of year one and categorized 81 radionuclides into three distinct groups during Year 2. In addition, dose coefficients were generated for radionuclides that fell into Category 1. During Year 3, the main concentration of the consortium’s time will be devoted to obtaining nuclear data that will allow dose coefficients to be calculated for Category 2 and 3 radionuclides and to calculate dose coefficients for those in Category 2.
