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.”

The 99Tc(n,γ) average cross section was measured at the Oak Ridge Electron Linear Accelerator from 2.65 to 2000 keV with an estimated uncertainty ranging from 4.0 to 4.9%. Individual resonance parameters were fitted by least-squares adjustment to the capture yield data from 2.65 to 5.08 keV. The average cross-section data agree with the ENDF/B-V (Mod 1) evaluation above 900 keV and lie within ±15% of the JENDL-1 evaluation below 700 keV.
