ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

Because the Versatile Test Reactor (VTR) uses sodium as a primary and secondary coolant, an analysis of postulated sodium leaks that could result in sodium fires is needed for VTR safety analysis. The goals of such an analysis include, among other topics, determination of temperature and pressure loadings on the reactor building from sodium fires. This paper provides a description of sodium spray and pool fire analysis tool development at Argonne National Laboratory for application to the VTR and includes validation against available data from sodium fire experiments.
