Powering the future: How the DOE is fueling nuclear fuel cycle research and development
As global interest in nuclear energy surges, the United States must remain at the forefront of research and development to ensure national energy security, advance nuclear technologies, and promote international cooperation on safety and nonproliferation. A crucial step in achieving this is analyzing how funding and resources are allocated to better understand how to direct future research and development. The Department of Energy has spearheaded this effort by funding hundreds of research projects across the country through the Nuclear Energy University Program (NEUP). This initiative has empowered dozens of universities to collaborate toward a nuclear-friendly future.

A self-powered neutron detector (SPND) was developed and tested in a 250-kW TRIGA Mark II reactor, using 93% 235U-enriched uranium as emitter material. Contrary to conventional SPNDs where the charge transfer from emitter to collector is performed by electrons, the present detector current originates in the transfer of highly ionized fission fragments through a very thin insulation layer. The theoretical evaluations indicated a detector sensitivity increase of a factor of 100 compared with a commercial cobalt detector together with such other advantages as the same spectral response and the same burnup characteristics as the reactor fuel.
