EPA administrator Lee Zeldin talks the future of nuclear
In a recent interview on New York radio station 77 WABC, administrator of the Environmental Protection Agency Lee Zeldin talked with host John Catsimatidis about the near-term future of the domestic nuclear industry and the role the EPA will play in the sector.
Catsimatidis kicked off the interview by asking if the U.S. will be able to reach total energy independence. Zeldin responded by saying that decreasing energy dependence on other countries, especially adversaries, was a top priority for him and the Trump administration.

The absolute 125-deg differential gamma-ray production cross section for the 1780-keV transition in the 28Si(n,n′γ)28Si reaction has been measured from 1.96- to 4.15-MeV bombarding energy. This transition represents the decay of the 2+ first excited state to the 0+ ground state of 28Si. The data were corrected for neutron multiple scattering as well as neutron and gamma-ray attenuation in the sample. The angle-integrated neutron scattering cross section was inferred from the gamma-ray production data using the shape of the gamma-ray angular distributions obtained from compound nucleus statistical model calculations. Incident neutrons were produced via the 3H(p,n)3 He reaction using a target ∼100 keV thick for 3.5-MeV protons, and this energy spread is reflected in the structure observed in the cross section.
