Senate committee advances NRC nominee Matthew Marzano
Marzano
The U.S. Senate Environment and Public Works Committee voted 10–9 last week to advance the nomination of Matthew Marzano to serve on the Nuclear Regulatory Commission. It was a party-line vote, with all Democrats supporting Marzano and all Republicans voting “no.”
Marzano was nominated by President Biden in July to fill the open NRC seat, and the EPW Committee held a hearing in September on his nomination. His nomination will now go to the Senate for a vote, but it is not certain whether that will happen before the end of the year, in which case his nomination process would start over in 2025.
The five-member commission has been without a tiebreaker vote since June 2023 when Jeff Baran’s term expired.

The objective of the present study is to analyze separation capability of charged particles of small-scale cusp type direct energy experimental converter installed at GAMMA 10 by means of numerical simulation with the axisymmetrical two-dimensional approximation. The numerical simulation has given the following results: (1) when the input power of protons is less than or equal to 1W, the protons and the electrons can be separated with the proton collection efficiency of 100%. When the input power of protons is 5W, the protons and the electrons become difficult to be separated with the proton collection efficiency of about 5%. (2) The electrons whose radius of incidence is small become trapped in the separation zone. These results depend on the magnitude of self-induced electric field which is formed by separation of the protons and the electrons.
