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 method based on a forward dynamic programming technique is applied to load-following control of a boiling water reactor. The control strategy obtained is optimal and satisfies operation constraints. A coarse-mesh, one-dimensional model using the two-group diffusion theory with Doppler, void, and xenon feedbacks is developed to reduce computer time. The control rods are assumed to be fixed during load maneuvers, and variations in core power are accomplished through core flow. An off-line daily load-following analysis needs ∼2000 CPU s on a PRIME 9950 computer. With some relaxation, computation time can be reduced to several hundred seconds. Thus, an on-line calculation that leads to an approximate closed-loop control is feasible.
