NRC’s David Wright visits the Hill and more NRC news
The Nuclear Regulatory Commission is in the spotlight today for three very different reasons. First, NRC Chair David Wright was on the Hill yesterday for his renomination hearing in front of the Senate’s Environment and Public Works Committee. Second, the NRC released its updated milestone schedules according to the Nuclear Energy Innovation and Modernization Act (NEIMA) and the executive orders signed by President Trump last month; and third, as reported by Reuters on Tuesday, 28 former NRC officials have condemned the dismissal of Commissioner Hanson earlier this month.

An experimental program has been developed at Los Alamos Neutron Science Center to precisely measure fission cross sections relevant to advanced nuclear reactor designs and transmutation concepts. The first completed measurement is of 237Np(n,f), and the subthreshold part of the measurement is reported here. The JENDL-3.3 evaluation agrees well with the experimental results in the unresolved resonance region, where a discrepancy between the ENDF/B-VI and JENDL-3.3 evaluations exists.
