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.

A compact diagnostic system for monitoring Hard X-Ray (HXR) in the KSTAR tokamak has been developed in this work. Its development aims for an extension of the counting rate limit, and a good time resolution in the hard X-ray diagnostic. The all-in-one compact HXR diagnostic system is based on NaI(Tl) scintillation detector, because this scintillator provides reliable identification of the X-ray energy spectra with high efficiency. And in addition, the electronic equipment such as preamplifier, main amplifier, high voltage power supply, and fast analog-to-digital converter (ADC) with a digital signal processor (DSP) system was built-in on boards as compact modules in the system. In particular, a fast ADC based on a DSP, and an amplifier with a shaping time of 100 ns was adopted to achieve 1 ms time resolution and a higher counting rate up to 1 MHz. This diagnostic system is intended to provide information on dynamic mechanisms of the high-energy electrons arising from when runaway electrons interact with plasma-facing components in the KSTAR tokamak.
