Senate committee hears from energy secretary nominee Chris Wright
Wright
Chris Wright, president-elect Trump’s pick to lead the U.S. Department of Energy, spent hours today fielding questions from members of the U.S. Senate’s committee on Energy and Natural Resources.
During the hearing, Wright—who’s spent most of his career in fossil fuels—made comments in support of nuclear energy and efforts to expand domestic generation in the near future. Asked what actions he would take as energy secretary to improve the development and deployment of SMRs, Wright said: “It’s a big challenge, and I’m new to government, so I can’t list off the five levers I can pull. But (I’ve been in discussions) about how to make it easier to research, to invest, to build things. The DOE has land at some of its facilities that can be helpful in this regard.”

Severe accident codes, i.e., codes that model core meltdown and accident progression in light water reactors, do not currently make use of parallel processing technology. Previous efforts to parallelize severe accident codes using DO-loop or data partitioning have resulted in speedup factors of <2.0 because of large serial code sections. Severe accident codes are more amenable to the functional partitioning approach, which splits a code into parallel tasks each representing a separate physical model. When combined, the two methods are able to partition 95% of the HECTR containment analysis code. Overall speedups of 2.6 and 3.2 on four and eight processors are obtained with the parallel HECTR code on an Alliant FX/80 parallel computer when modeling a moderately sized accident scenario. Speedups are expected to increase for larger severe accident codes, such as MELCOR, which contain more functional parallelism than the HECTR code.
