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.

The ability to efficiently model coupled electron-photon transport is essential for determining the response of electronics components to nuclear radiation environments. Furthermore, to fully characterize the effect of many different radiation environments on a component, an adjoint transport capability is desirable. The theory of adjoint electron-photon transport is described with the CEPXSZONEDANT-LD discrete ordinates code package and the method is applied to a set of example problems representative of those encountered in radiation effects testing. Adjoint transport, in addition to efficiently modeling radiation source variations, can effectively model geometry variations for certain classes of problems. A new linear-discontinuous approximation of the continuous slowing down operator that introduces no upscatter is also developed.
