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.

A Monte Carlo code is used to calculate the fast effect in both homogeneous and heterogeneous systems. The following results are obtained: for an infinite block of natural uranium, δ28 = 0.39, ∈ = 1.247; for an infinite block of beryllium, ∈ = 1.078; for beryllium oxide, ∈ = 1.046. In addition, results are given for homogeneous mixtures of uranium and beryllium. Calculations have also been carried out for uranium-water lattices and compared with experimental results for slightly enriched uranium rods and slabs, and uranium oxide rods. Other results show the increase in ∈ when uranium fuel elements are surrounded by beryllium cladding of varying thickness.
