Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.

Based on the results of neutral transport simulation using cylindrical mesh-model, the effect of the plasma edge region was investigated in the GAMMA 10 central-cell. 3-dimensional geometry and neutral sources such as gas puffers, limiters, and neutral beam injection are precisely constructed in the mesh-model of the GAMMA 10 central-cell. From the neutral transport simulation in the case of each neutral source, 1/e decay lengths of H-line intensity (H decay length) along with z-axis were evaluated. It was found that H-line intensity calculated by the simulation of the gas puffer #3(GP#3) in mirror-throat region takes a broader profile than that of central-limiter and gas puffer #7(GP#7) around the central mid-plane region because the plasma density is low in mirror-throat and the neutral particles are given near the vacuum vessel, while the neutral particles in the central-limiter are given near the plasma core. The simulation results also revealed that the H-line intensity drastically decrease in the range with interior components. On the other hand, it was clarified that the H-line intensity in no interior component area takes a little reduction because of a large width in plasma edge region.
