From renaissance to reality: Infrastructure for a global nuclear fuel cycle
Dale Klein
This article was adapted from the author’s speech during a plenary at the 21st International Symposium on the Packaging and Transportation of Radioactive Materials (PATRAM 2025), San Antonio, Texas, July 2025.
There has been a lot of discussion lately about reforming the Nuclear Regulatory Commission. But I want to be clear: When it comes to nuclear safety and security, there is no place for partisan politics. I support efforts to streamline regulatory processes, but the independence and integrity of the NRC must remain sacrosanct. If we are serious about expanding nuclear power and reclaiming our global leadership in nuclear technology, having a strong independent regulator is fundamental.
Right now, we’re on the edge of a global nuclear resurgence driven by rising demand from data centers, growing concerns about energy security, and the need to decarbonize industry.

PDP is a very interesting phenomenon and presents a significant problem to the fuel control and the safety in Tokamak devices. Systematic experimental studies on the PDP mechanism using an ECR discharge plasma have been carried out to investigate the role of the neutrals and to estimate the isotope effects occurred in PDP for H, D, and T. The maximum isotope effects observed are 1.42 for H/D, and 1.1 for a D/T mixed plasma in the case of SUS 304 test membrane. The magnitudes of the isotope effects between the three hydrogen isotopes are satisfactorily explained by the role of neutrals in PDP.
