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.

Efficient operation of the gas neutralizer is important to the neutral beam injection (NBI) system, which forms part of the auxiliary heating systems for Experimental Advanced Superconducting Tokamak (EAST). The particle transport through the beamline of the EAST NBI system was investigated by the recently developed numerical simulation code based on the Monte Carlo treatment of collisions. This paper reports the simulation results on the ion beam transport through the EAST neutralizer and the beam deflections in the neutralizer due to the EAST stray magnetic field. The results show that the current design of the magnetic shield for the EAST neutralizer is able to meet the requirement. The relations of the optimal neutralizer thickness to the beam energy and the corresponding fractional power carried by each particle species are also given.
