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 slowing-down distribution of Po-Be neutrons has been measured in aluminum-water, zirconium-water, and iron-water mixtures up to metal water ratios of 2:1 by volume. The second moment of the distribution has been obtained from these measurements and compared with theoretical calculations based on a solution of the transport equation. The effect of varying the source spectrum and cross sections in the calculations is discussed.
