The International Atomic Energy Agency has signed an agreement with Japan’s Okayama University that provides a three-year framework for enhanced cooperation in boron neutron capture therapy (BNCT), the IAEA announced on June 24. BNCT is a noninvasive therapeutic technique for treating invasive malignant tumors.

A team of researchers at the Department of Energy’s Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease, the enzyme that enables the virus to reproduce.
The X-ray measurements mark an important first step in the researchers’ ultimate goal of building a comprehensive 3D model of the enzymatic protein.
The Department of Energy on June 23 announced the selection of 76 scientists from across the United States—26 from the DOE’s national laboratories and 50 from U.S. universities—to receive significant funding for research as part of the DOE Office of Science’s Early Career Research Program. The effort, now in its 11th year, is designed to bolster the nation’s scientific workforce by providing support to exceptional researchers during the crucial early career years, when many scientists do their most formative work.
A team of Lawrence Berkeley National Laboratory (LBNL) scientists has discovered a new form of the human-made element mendelevium, LBNL reported on June 23. The newly created isotope, mendelevium-244, is the 17th and lightest form of mendelevium, which is element 101 on the periodic table.
Nuclear technology for space exploration just took a giant step forward. Researchers at the National Nuclear Security Administration and the National Aeronautics and Space Administration have conducted a series of tests as part of NASA’s Kilopower project for the development of a nuclear space reactor. The results have been published in a special issue of the American Nuclear Society’s journal Nuclear Technology, which includes eight papers that cover the design and testing of the Kilowatt Reactor Using Stirling TechnologY (KRUSTY) reactor, a 1-kWe space reactor with a cast uranium core, heat pipes, and Stirling engine power conversion.
Brouillette
Energy Secretary Dan Brouillette said in a June 1 announcement to Department of Energy employees that given the recent lifting of stay-at-home orders in the Washington, D.C., area, the department will allow some federal employees to return to work at DOE headquarters, beginning on June 8.

ITER, the world’s largest international scientific collaboration, is beginning the assembly of the fusion reactor tokamak that will include 12 essential hardware systems provided by US ITER, which is managed by Oak Ridge National Laboratory. The first major machine element to be installed is the 1,250-ton base of the cryostat, which was placed into the tokamak assembly pit on May 26. ITER is located in southeastern France.
To get a job done, you need the right tool. Researchers now have one that will make their job easier—the Radioactivity and Damage (RAD) Calculator from the Department of Energy’s Nuclear Science User Facilities.
Most experiments conducted through the NSUF have the same underlying goal: quantifying irradiation effects on nuclear fuels and materials. Rather than doing a back-of-the-envelope calculation or a costly in-depth analysis with a nuclear engineer, users now have the flexibility to rapidly change experimental design parameters—such as selecting the reactor to be used, the sample location within the reactor, displacements per atom desired, and the time frame—and see which NSUF reactor can produce the desired result, all within seconds.

There are a lot of reasons that a faster spaceship is a better one, and nuclear-powered rockets are a way to achieve this, according to an article posted on the Conversation website on May 20.

The Transient Reactor Test (TREAT) Facility at Idaho National Laboratory was restarted in 2018 after being in safe standby mode since 1994. The June 2020 issue of the American Nuclear Society's Nuclear Technology (NT) journal features seven technical papers related to the benchmarking of the facility. Wade Marcum, a lead researcher on the project and guest editor of June’s NT issue, explained, “The goal of this effort was to understand, to the best of our ability, the expected response of the TREAT reactor upon its restart.”
A collaborating center agreement was signed by Elettra Sincrotrone Trieste and the International Atomic Energy Agency in May. The agreement focuses on advanced light sources and will support countries in research, development, and capacity building in the application of advanced and innovative radiation technologies.
Brouillette
In remarks addressed to a meeting of the National Space Council on May 19, Energy Secretary Dan Brouillette said that the development and deployment of small modular reactors could provide sustainable power sources for space applications.
The Department of Energy is awarding $27 million in funding for nine projects through the Advanced Research Projects Agency–Energy’s (ARPA-E) Generating Electricity Managed by Intelligent Nuclear Assets (GEMINA) program. These projects will work to develop digital twin technology to reduce operations and maintenance (O&M) costs in the next generation of nuclear power plants in order to make them more economical, flexible, and efficient, according to the DOE.

An initiative by the International Atomic Energy Agency to help nearly 120 countries contain the COVID-19 pandemic has received a financial boost from member states and Takeda Pharmaceutical Company Limited.
The IAEA announced on May 13 that Takeda, a biopharmaceutical company based in Tokyo, donated 500 million yen (about US$4.7 million). Two days earlier, the IAEA announced that pledges from more than 10 member nations totaled €22 million (about US$23.8 million).
Today, the U.S. Department of Energy announced the launch of the Advanced Reactor Demonstration Program (ARDP) within the Office of Nuclear Energy. ARDP is designed to help domestic private industry demonstrate advanced nuclear reactors in the U.S.
Shine Medical Technologies, which is building a medical isotope production facility in Janesville, Wis., said on May 11 that it expects to have an operating license issued by the Nuclear Regulatory Commission by October 2021. Shine’s application seeking approval to operate the facility, which will produce isotopes including molybdenum-99, was accepted and docketed by the NRC last October. Mo-99, the precursor to technetium-99m, is used in more than 40 million medical patient procedures every year.
When it comes to advanced, high-temperature reactors—using working fluids such as molten salt, high-temperature gases, or sodium—there simply are not many qualified materials for nuclear component construction. Alloy 617 is not a new material, but it made the news after Idaho National Laboratory announced that it was recently added to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV) Code for high-temperature nuclear applications, bringing the total number of qualified high-temperature materials to six.
Belgium’s National Institute of Radioelements (IRE) announced on April 30 that it has produced its first batch of commercial molybdenum-99 from low-enriched uranium (LEU) targets. The first batch of Mo-99, whose decay product, technetium-99m, is used in nuclear medicine for diagnostic imaging, was produced for the U.S. health market. IRE said that the conversion to LEU represents a key milestone for the institute in the global commitment to end the civilian use of highly enriched uranium (HEU) for the production of Mo-99.
