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.

The target area of a 288-beam inertial confinement fusion laser driver was designed to allow lasers for direct-drive illumination, spherical hohlraum with six laser entrance holes (6LEHs), and baseline cylindrical hohlraums. The suggested radius of a target chamber was 6.0 m based on the ratio of the total port area to chamber area. Beam port distribution on the chamber was calculated if the direct propagation of laser beams into opposing beam ports was avoided, and this distribution was compatible with spherical hohlraums with 6LEHs without additional ports opened. According to the symmetry of the beam port distribution, an X-shaped beam-guiding system (BGS) in the switchyard was proposed and arranged within a baseline algorithm. The switch between direct- and indirect-drive modes was easy to operate using this BGS concept.
