After serving two years as the Department of Energy’s assistant secretary for Nuclear Energy, Kathryn Huff will vacate that position on May 3 and return to teaching. Huff had started at the DOE in May 2021, serving for one year as the principal deputy assistant secretary for Nuclear Energy.

“Serving in this capacity has been an unparalleled privilege, and I’m immensely grateful for the opportunity to have worked alongside you--the dedicated and talented public servants in Nuclear Energy, in DOE, and across the Biden-Harris Administration,” Huff wrote in an email announcement to colleagues last week. “I chose this timing to enable the smoothest transition back to my professorship at the University of Illinois at Urbana-Champaign where my beloved research, students, husband, and dog await.”

Clean Core Thorium Energy (Clean Core) has announced that its ANEEL fuel is ready to begin irradiation testing and qualification at Idaho National Laboratory. The fuel, made of thorium and HALEU, was developed by Clean Core for use in pressurized heavy water reactors, including CANDU (Canadian deuterium-uranium) reactors. Irradiation of the fuel samples in INL’s Advanced Test Reactor (ATR) is set to begin this month.

The Department of Energy’s Office of Environmental Management recently announced that crews at the Hanford Site’s Waste Treatment and Immobilization Plant, also known as the Vit Plant, recently brought the second of two 300-ton melters up to the operating temperature of 2,100°F.

Nuclear Regulatory Commission staff will host a public information meeting on Wednesday, April 17, to discuss plans for repowering the shuttered Palisades nuclear plant in Michigan.

Researchers at the Department of Energy’s Argonne National Laboratory are developing and deploying ARG-US (from the Greek Argus, meaning “Watchful Guardian”) remote monitoring systems technologies to enhance the safety, security, and safeguards (3S) of packages of nuclear and other radioactive material during storage, transportation, and disposal.

TerraPower’s application to build its Natrium nuclear power plant near Kemmerer, Wyo., is available for public viewing on the Nuclear Regulatory Commission website.

Laser Photonics Corporation and Brokk Inc. have announced the forming of a technology partnership to bring laser cleaning and cutting technology to the nuclear disposal, decommissioning, mining, tunneling, construction, metal processing, and military industries.

The American Nuclear Society (ANS) condemns the recent drone attacks at Ukraine’s shutdown Zaporizhzhia Nuclear Power Plant (ZNPP) and supports the International Atomic Energy Agency (IAEA) Board of Governors in its continued call for an immediate removal of Russian military and personnel from ZNPP.

Imagine what our world would be like today without the benefits of electric energy. Think of the inventions and technologies that never would have been. Think of a world without power grids and the electricity that makes them run. Without this power, we’d find it difficult to maintain our industrial and manufacturing bases or enable advancements in the fields of medicine, communications, and computing.

Now consider the moon, our closest celestial neighbor about which we still know so little, waiting for modern-day explorers in spacesuits to unveil its secrets. Lunar exploration and a future lunar economy require reliable, long-lasting, clean sources of power. Nuclear fission answers that call. When assessing the application of nuclear power in space, three Ps should be considered: the present, the potential, and the partnerships.

The first unit at Akkuyu, Turkey’s first nuclear power plant, has begun the commissioning process. The goal is that the plant will begin supplying energy to the nation next year, according to Rosatom, Russia’s state atomic energy corporation.

Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory are using a stellarator they designed and built using permanent rare-earth magnets and a 3D-printed shell to help test new fusion power concepts. MUSE—the first stellarator built at PPPL in 50 years—took one year to construct and generated its first plasma in February 2023. The work that went into its design has already inspired a stellarator power plant concept being developed by a commercial spin-off, Thea Energy.

Next-generation reactor company Oklo Inc. is teaming up with Diamondback Energy Inc. to bring Oklo’s Aurora Powerhouse units to the American Southwest.

The companies signed a nonbinding letter of intent (LOI) this week to collaborate on a 20-year power purchase agreement that would provide 50 MW of electricity per unit to Diamondback’s Permian Basin operations area. The agreement lays out options to renew and extend the agreement for an additional 20-year term, since the units are designed to operate for 40 years without needing to refuel. Diamondback is an independent oil and gas company headquartered in Texas.

Last year in late August, 120 storage cylinders of depleted uranium oxide (DUOx) safely arrived by rail in West Texas, having been shipped from the Department of Energy’s Portsmouth Site in Ohio. It was the first such shipment of the stable crystalline powder from the Portsmouth Site and was another milestone in the DOE Office of Environmental Management’s (EM) efforts to ship DUOx for off-site disposal.

Unit 2 of South Korea’s Shin-Hanul nuclear power plant entered commercial operation on April 5, Korea Hydro & Nuclear Power announced. It is the nation’s 26th operating reactor, which continues the upward nuclear trend as South Korea reverses a previous phase-out plan for nuclear.

Energy secretary Jennifer Granholm submitted a Department of Energy report to the U.S. Congress on April 8 detailing the state of research reactors at U.S. universities and the potential need to upgrade or build additional reactors, including advanced nuclear reactors and test facilities.

Systems for Nuclear Auxiliary Power (SNAP) was an Atomic Energy Commission program with the goal of producing a portable and dependable power source centered around nuclear technology that could be utilized in land, sea, and space applications. The program aimed to provide a compact reactor—a necessity for space applications—and ran from 1955 until 1973, when it was discontinued.

To help expand access to clean nuclear energy, the Department of Energy announced it has awarded more than $19.1 million to support nuclear energy research and development, university nuclear infrastructure, and undergraduate and graduate education.

U.S.-based reactor company X-energy has partnered with Canadian power producer TransAlta Corp. to study the feasibility of deploying an advanced small modular reactor at a fossil fuel power plant site in Alberta.

Once used for applications in medicine, industry, and research, many countries now have legacy radium-226 sources, according to the International Atomic Energy Agency. With the support of the IAEA’s technical cooperation program, these disused sealed radioactive sources are being recovered, and countries are improving national capacities for their long-term management, including their potential reuse and recycling.
