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.”

An intense reusable source of pulsed photoneutrons is developed that produces ≈0.5 or 1.0 × 1014 neutrons in an ∼15-ns pulse from natural lead or depleted uranium, respectively, on the HERMES III electron accelerator. Corresponding to this source, a numerical model is developed that is applicable to other pulsed-power systems. If Vp represents the peak voltage of HERMES III measured in megavolts, then model predictions show that over the range 12 MV < Vp< 20 MV, the number of neutrons produced per incident electron is 7.2 × 10-6(VP — 11)2.0 and 1.2 × 10-6(VP — 7.4)2 8 in lead and uranium, respectively. Measurements using a set of nuclear activation foils confirm these predictions as well as predictions of the spatial and spectral distribution of the neutrons at Vp = 19 MV.
