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.

Gamma-ray heating rates from 60Co and 137Cs are measured independently in a stainless steel sphere using thermoluminescent dosimeters (TLDs) with different sensitivities and atomic numbers, a useful check on dosimetric measurements. Gamma-ray dose-weighting f factors, based on the general cavity ionization theory, are applied to convert the net TLD dose rates into gamma-ray heating rates in stainless steel. Gamma-ray spectra are calculated using the ANISN computer code together with the DLC-41/VITAMINC cross-section library. The experimental and the calculated gamma-ray heating rates are compared. The calculation-to-experiment (C/E) ratios of the heating rates are close to unity at experimental positions near the gamma-ray source and show drop-off at far positions. This C/E discrepancy comes primarily from the calculations; however, there is a minor contribution to the C/E discrepancy from the TLD overresponse at low gamma energies.
