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.

An experience with the vectorization of the light water reactor transient analysis code RELAP5/MODI on a vector supercomputer FACOM VP-100 (peak speed 250 million floating point operations/s, clock period 7.5 ns) is described. The approach to the vectorization is based on the junction and volume level parallelisms for the hydrodynamic model, and the heat structure and heat mesh levels for the heat transfer model. The VP-100 vectorized code version yields a 2.4 to 2.8 factor speed increase over the FACOM M-380 computer, depending on the number of spatial cells being used. The M-380 is an IBM-type computer with the same speed as the VP-100 in scalar mode.
