Ho Nieh, TVA board members, and nuclear fuel recycling bill head to Senate floor
Nieh
Ho Nieh, the Trump administration’s nominee to be a member of the Nuclear Regulatory Commission, and four new board members of the Tennessee Valley Authority were approved in a vote today by the Senate Environment and Public Works Committee and head to the Senate floor for a final vote.
The committee also voted to advance to the Senate floor the Nuclear REFUEL Act of 2025 (S. 2082), which would smooth the regulatory pathway for recycling used nuclear fuel.
President Donald nominated Nieh on July 30 to serve as NRC commissioner for the remainder of a term set to expire June 30, 2029, which was held by former NRC commissioner Chris Hanson, who Trump fired in June.

The report presents the recent results of experiments with deuterium neutral beam injection in the Gas Dynamic Trap (GDT) device. The experiments were to demonstrate the peaking up of the DD reaction near the fast ion turning points that represents the essential feature of the GDT-based neutron source (GDT-NS). The critical assumption for feasibility of GDT-NS is that the fast ion relaxation in the warm target plasma is to be determined by two-body Coulomb collisions without considerable increase of the scattering rate caused by instabilities, otherwise the neutron flux peaks may strongly flatten out. The comparison of the measured axial profile of the DD reaction intensity with simulation results allows to validate this assumption for the plasma parameters of GDT device
