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 preferential site, segregation and embrittlement properties of hydrogen (H) in a vanadium (V) &Sgr;3 (111) [110] grain boundary (GB) were investigated by first-principles calculations. The solution and segregation energy of H at different interstitial and substitutional sites are calculated. Energetically, H prefers to occupy the GB space rather than substitutional sites and can segregate to the GB with segregation energy of −0.08 eV. Hydrogen is an embrittler at the GB by producing an embrittlement energy of about 0.41 eV, in agreement with experimental observations. Charge density distributions indicate that there are no strong chemical bonds between an H atom and the adjacent V atoms in the GB, and the presence of H atom weakens the bond strength between surrounding V atoms.
