Lawrence Livermore National Laboratory is celebrating the yield from an experiment at the National Ignition Facility (NIF) of more than 1.3 megajoules of energy—eight times more than the yield from experiments conducted this spring and 25 times more than NIF’s 2018 record yield.

The Max Planck Institute for Plasma Physics (IPP) was founded in Garching, Germany, in 1960, the same year that its Wendelstein 1a stellarator began operation. Wendelstein 7-X is now operating at IPP’s site in Greifswald, Germany, and one of the objectives the device was designed to achieve has recently been confirmed, IPP announced on August 12. Analysis by IPP scientists shows that the twisted magnetic coils of the device successfully control plasma energy losses, indicating that stellarator fusion devices could be suitable for power plants, according to a detailed analysis of experimental results published on August 11 in Nature.

Rensselaer Polytechnic Institute will use $1.5 million in grants from the Department of Energy to lead projects aimed at upgrading nuclear power plant efficiency and safety, the university announced earlier this month. The grants are part of more than $61 million in awards recently announced by the DOE to support nuclear energy research.

The Department of Energy announced in 2020 its approval of Critical Decision 1 for the Versatile Test Reactor (VTR) project, a one-of-a-kind scientific user facility that would support research and development of innovative nuclear energy and other technologies. The decision was well received by the nuclear energy community—after all, the DOE’s Nuclear Energy Advisory Committee had studied and reported on the need for the VTR and found strong support for the project among reactor developers, federal agencies and national laboratories, and university researchers.

The white plumes of steam billowing from the cooling towers of nuclear power plants and other thermal power plants represent an opportunity to some—the opportunity to collect a valued resource, purified water, that is now lost to the atmosphere. A small company called Infinite Cooling is looking to commercialize a technology recently developed at the Massachusetts Institute of Technology by the Varanasi Research Group, whose work is described in an article written by David L. Chandler, of the MIT News Office, and published on August 3.

A bipartisan group of legislators has introduced a bill to invest in university nuclear science and engineering infrastructure, establish regional consortia to promote collaboration with industry and national laboratories, and support the development of advanced reactor technology. The National Nuclear University Research Infrastructure Reinvestment Act of 2021 (H.R. 4819) was introduced in the House of Representatives by Reps. Anthony Gonzalez (R., Ohio), Sean Casten (D., Ill.), Peter Meijer (R., Mich.), and Bill Foster (D., Ill).

Kathryn Huff, the Department of Energy’s acting assistant secretary for nuclear energy, asserted in an article published online by the Office of Nuclear Energy (DOE-NE) on July 30 that demonstration reactors, such as the Natrium and Xe-100 reactors being built as full-size power producers with cost-shared funding from the DOE, and test reactors, such as the Versatile Test Reactor, are both necessary for nuclear innovation. Both are also line items in the DOE budget request, and Huff’s article sends a clear message to appropriators about the need to fund both the Advanced Reactor Demonstration Program (ARDP) and the VTR.

Key facilities at a multipurpose nuclear research center in the high plains of Bolivia are nearing operation, and a ceremonial first concrete pour for the nuclear research reactor that will serve as the centerpiece of the project was held on July 26. Bolivian president Luis Arce attended the ceremony at the Center for Nuclear Technology Research and Development (CNTRD). Also attending were Kirill Komarov, first deputy director general for corporate development and international business at Rosatom (Russia’s state atomic energy agency), and authorities from the Ministry of Hydrocarbons and Energies and the Bolivian Nuclear Energy Agency (ABEN).

The Department of Energy’s Office of Science (DOE-SC) and the National Nuclear Security Administration (NNSA) on July 27 announced $9.35 million for 21 research projects in high-energy-density laboratory plasmas. High-energy-density (HED) plasma research, originally developed to support the U.S. nuclear weapons program, has applications in astrophysics, fusion power plant development, medicine, nuclear and particle physics, and radioisotope production.

In July 1969, the public’s attention was fixated on NASA’s Apollo 11 mission—a “giant leap for mankind” that was memorably marked by Neil Armstrong as he stepped onto the surface of the moon. This July, the possibilities of spaceflight are once again capturing the public’s imagination and news headlines. While NASA invests in nuclear propulsion research and development to stretch the limits of U.S. space missions, private companies Virgin Galactic and Blue Origin are stretching the definition of “astronaut” and proving they can offer a high-altitude thrill to paying customers.

China is moving ahead with the development of an experimental reactor that would be the first of its kind in the world and “could prove key to the pursuit of clean and safe nuclear power,” according to an article in New Atlas.

A statistically predicted tendency for neutrons produced inside fission reactors to form in clusters can cause asymmetrical energy production that is counterbalanced, at least in part, by the spontaneous fission of radioactive material in the reactor.

With the capacity to treat 30,000 cubic meters of wastewater per day, the largest industrial wastewater treatment facility using electron beam technology in the world was inaugurated in China in June 2020. The treatment process has the capacity to save 4.5 million m3 of fresh water annually—equivalent to the amount of water consumed by about 100,000 people.

Scientists from the Jozef Stefan Institute in Slovenia, with technical advice and analytical support from the International Atomic Energy Agency and the Food and Agriculture Organization of the United Nations, are studying the composition of truffles—a rare and expensive type of mushroom—in order to determine their origin and help detect fraud. Thanks to a database and the techniques developed, other laboratories worldwide can also test truffles, establish their geographical origin, and verify whether they are genuine.
