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.

During the startup phase of the thorium high-temperature reactor (THTR)-300, control rod reactivity measurements are performed to meet the demands of the licensing authorities as well as to adjust the operating instrumentation. From several possibilities the inverse kinetic method has been chosen because of its easy implementation, high stability against disturbing signals, and great accuracy. An outline of the basic assumptions of various methods together with tests on the Kritische Anlage Hochtemperaturreaktor are discussed, the technical equipment for the THTR is described, and results of measurements for various rod configurations are given. Finally, the transition from the special startup equipment to the standard operating instrumentation is demonstrated.
