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 discrete angle technique is a customary method for selecting scattering angles from such scattering laws that are given through their Legendre coefficients up to some finite order. In this technique, discrete scattering angles are selected with certain probabilities. In low-order Pn truncations, however, this method can lead to unwanted ray effects during the first few free flights of the random walk. We propose a method in which a linear combination of some arbitrary density function, having the same first 2n moments as the truncated expansion, and of a discrete density function will yield samples that conserve the first (2n + 2) moments of the truncated series. Bounds are derived on the possible ranges of the combination coefficient. The method is applied to construct a semicontinuous density function (continuous + Dirac delta functions) having the first four moments prescribed, i.e., being given by its first three Legendre coefficients.
