Feedback from nuclear sector to inform hearing on NRC licensing process
Leaders of the House Committee on Energy and Commerce last month sent letters to a variety of nuclear sector stakeholders requesting input in preparation for a June 14 hearing titled “Oversight of NRC: Ensuring Efficient and Predictable Nuclear Safety Regulation for a Prosperous America.” (The hearing will be livestreamed at https://energycommerce.house.gov/.)
“We invite you to submit to the committee information and recommendations to improve the licensing review and approval process, as well as the oversight of NRC licensees,” the lawmakers wrote. “We are interested in NRC activities involving the licensing and oversight of today’s operating reactors, as well as the siting, licensing, construction, and oversight of advanced nuclear reactor technologies.” The letter also noted the committee’s interest in “improving NRC efficiency, management of regulatory costs and fees, public health and safety, staff effectiveness and culture, collaboration with the Department of Energy, and international activities.”

Rates of neutron production in deuterium-tritium (D-T) plasmas below the temperature of 100 keV have been widely studied with analytical cross sections based on nuclear physics. In the present work, a new algorithm of numerical simulation using the latest nuclear database ENDF/B-VII, discrete ordinate (SN) method, and Monte Carlo methods was developed to describe nuclear reactions in D-T plasma. Compared with the method that used analytical cross section, this new method can predict the nuclear reaction in plasma to several hundreds of kilo-electron-volts and has the potential to give information about directionality of the neutron flux and other interesting nuclear reactions, if needed.
