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.

High-power-rating [≥1000 MW(electric)] passive pressure tube light water-cooled reactors are described that have the ability to reliably discharge decay heat to the ultimate heat sink, without the need to replenish primary coolant in loss-of-coolant accidents, while ensuring the integrity of the fuel and reusability of major reactor components. Evaluation shows that pressure tube reactors have the attractive potential to dissipate the decay heat from voided fuel elements of large-power-rating cores without exceeding safe temperature limits. Two basic versions of a pressure tube light water-cooled and -moderated reactor—the dry and wet calandria concepts—are proposed, and their advantages and limitations are discussed.
