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.

Deuterium retention after the low energy plasma irradiation was investigated using the polycrystalline tungsten samples of which grain elongation directions are parallel and perpendicular with respect to the surface. Fluence dependence of the retention measured by means of thermal desorption spectroscopy showed that it is 2-5 times larger for the sample with the perpendicular grain elongation. Thermal desorption of trapped deuterium has been modeled under the fast diffusion assumption with the defects trapping energy of about 2 eV. Possible mechanism of the deuterium retention and thermal desorption has been proposed.
