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.

A helium-cooled divertor concept for DEMO, which is currently being developed at the Karlsruhe Institute of Technology, uses a modular structure of tungsten 9-finger units composed of smaller individual one-finger modules. As the development of the 1-finger design is so far advanced, the work currently focuses on the manufacturing technology of a larger unit, the 9-finger module. The requirements for a larger grouping of individual cooling fingers are associated with the three-dimensional dimensions and orientations of all components in the assembly; their inaccuracy will affect the He flow distribution and cooling capacity of the divertor. In this paper, the necessary production steps, the order of assembly, and the principle of SATIR non destructive examination are described, as a result of a technological study.
