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 semianalytic method to solve the multigroup transport equation is presented. Here, the collision source is represented as a piecewise continuous function in space, preserving its finite spatial moments. The angular flux is analytically evaluated. The performance of the method is compared with the DSN method in a problem of gamma-ray transport through a 1-m-thick block of iron. It is found that one can obtain accurate solutions with the present method using relatively coarse spatial cells, leading to a significant reduction in computing time.
