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.

This paper summarizes similitude requirements for liquid-metal fast breeder reactor natural convection shutdown heat removal test facilities. It is generally not possible under natural circulation flow to reproduce both hydrodynamic and thermodynamic similarity when the thermal driving head is determined by structure-to-fluid heat transfer. This paper explores the source of the scaling difficulties and examines a number of possible solutions. Design and operating restrictions imposed on the test facility and the validity of extrapolating test facility data to the full-scale system are discussed.
