Today’s atomic clocks are exceptional timepieces that won’t lose or gain a second in 30 billion years. But if you’re looking for even more precision, you’ll be glad to learn that physicists at CERN’s ISOLDE nuclear physics facility have observed the decay of thorium-229 nuclei trapped in a crystalline structure and confirmed the potential for a nuclear clock. CERN announced the news on May 24.

An electric-powered prototype of MARVEL, the tiny microreactor designed and planned for operation inside the Transient Reactor Test (TREAT) facility at Idaho National Laboratory, has successfully been installed at a manufacturing facility in Pennsylvania ahead of a testing program that could begin as early as July, the Department of Energy announced on May 22.

Zeno Power Systems was awarded a $30 million contract to build a radioisotope-powered satellite for the U.S. Air Force by 2025. According to a SpaceNews article announcing the development and quoting company cofounder and chief executive officer Tyler Bernstein, the four-year contract is a “strategic funding increase” (STRATFI) agreement that provides $15 million in government funds, matched by $15 million from private investors.

Lawrence Livermore National Laboratory hosted current and former staff, government officials, and media on May 8 to celebrate the lab’s achievement of fusion ignition at the National Ignition Facility (NIF) on December 5, 2022. Energy secretary Jennifer Granholm and undersecretary for nuclear security and National Nuclear Security Administration administrator Jill Hruby were in attendance, and Granholm took the opportunity to announce funding of up to $45 million to support inertial fusion energy (IFE) research and development. The Department of Energy’s Office of Science (DOE-SC) wants to establish multiple IFE Science and Technology Innovation Hubs (IFE S&T hubs), with total funding for 2023 of up to $9 million for projects lasting up to four years in duration.

With funding from the Islamic Development Bank (IsDB), the International Atomic Energy Agency is working to help developing countries scale up their cancer care capacities in radiotherapy, the agency said. A multilateral development bank, IsDB works to improve lives by promoting social and economic development in 57 member states and Muslim communities around the world.

Nuclear power is the single largest source of clean energy in the United States, but how can the value of “clean” be measured? Two recent reports by researchers at the Massachusetts Institute of Technology and Pacific Northwest National Laboratory, respectively, measured the clean energy benefits of nuclear energy in different ways: the benefits to human health from the air pollution avoided and the future economic value of avoided carbon emissions.

Researchers at Oak Ridge National Laboratory developed a method of using augmented reality (AR) to create accurate visual representations of ionizing radiation, and that technology has just been licensed by Teletrix, a Pittsburgh, Pa.-based firm that develops simulators to train radiological workers and radiological control technicians. ORNL announced the news on May 4.

Fusion development company SHINE Technologies announced that it will begin offering radiation effects testing in a dedicated facility on the company’s Janesville, Wis., campus later this year. SHINE will use high-energy fusion neutrons to test mission-critical components that are susceptible to radiation-harsh environments on behalf of its aerospace and defense customers.

The DIII-D National Fusion Facility in San Diego, Calif., has completed a monthlong research campaign using a negative triangularity plasma configuration inside its fusion tokamak and produced initial data that “appear very encouraging,” according to an April 24 news release from General Atomics (GA), which operates the Office of Science user facility on behalf of the Department of Energy. Full experimental results on “the highest-powered negative triangularity experiments in the history of the U.S. fusion research program” are expected this summer, according to GA.

Under the Radioisotope Power Systems Program, NASA and the Department of Energy have been advancing a novel radioisotope power system (RPS) based on dynamic energy conversion. This approach will manifest a dynamic RPS (DRPS) option with a conversion efficiency at least three times greater than a thermoelectric-based RPS. Significant progress has recently been made toward this end. A one-year system design phase has been completed by NASA industry partner Aerojet Rocketdyne, which resulted in a DRPS with power of 300 watts-electric (We) with convertor-level redundancy. In-house technology development at the NASA Glenn Research Center (GRC) has demonstrated the conversion devices in relevant environments and has shown all requirements can be met. Progress has also been made on the control electronics necessary for dynamic energy conversion. Flight-like controllers were recently upgraded and achieved an 11-percentage-point increase in efficiency. Control architectures have been developed to handle the multiconvertor arrangements in the latest DRPS design. A system-level DRPS testbed is currently being assembled that will experimentally demonstrate the DRPS concept being pursued.
