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 expression for the neutron escape probability from an absorbing body has been expressed in terms of two polynomials. The main feature of these polynomials is that only the coefficients depend on the shape of the geometry while the expressions remain same. At the same time, the resulting expressions for the escape probability ensure the correct behavior in the white and black limits. As examples, numerical results are presented for five geometries: a sphere, a slab, an infinite solid cylinder, a two-dimensional square geometry having infinite height, and a three-dimensional cuboid. The results obtained by using these polynomials match very well with the exact results obtained by using the program POLM, which solves numerically the exact expressions for the escape probability for the respective geometries.
