Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

Project management firm Bechtel started site geological surveys for Poland’s first nuclear power plant project, the company announced on Wednesday.

Bechtel will conduct in-depth geological surveys at the Lubiatowo-Kopalino site in the Pomeranian municipality of Choczewo, in northern Poland. This is a key milestone for the country’s entry into nuclear power production, as the surveys will inform the suitability of the planned site.

Advanced reactor company X-energy has been awarded $148.5 million in tax credits under the Inflation Reduction Act for construction of its TRISO-X fuel fabrication facility in Oak Ridge, Tenn.

Scientists at Argonne National Laboratory have partnered with Washington state–based Energy Northwest to look at alternative ways to cool nuclear reactors as climate change impacts relied-upon water sources.

The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.

According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

The International Atomic Energy Agency launched a collaboration with the Group of 20 this week to highlight the key role that nuclear energy can play in achieving energy security and climate-change goals.

The aim of this first-of-its-kind partnership with G20—the world’s largest economic group—is to build momentum for nuclear power. This is the first time the IAEA has presented to G20 on issues relating to nuclear power.

The Nuclear Regulatory Commission is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.

In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

Bulgarian officials have approved the transition to Westinghouse fuel at the nation's Kozloduy nuclear power plant, as Bulgaria moves away from its reliance on Russian supplies. The fuel was recently delivered for use in Unit 5.

Energy startup Last Energy took an opportunity last week to showcase a prototype of its micro-scale nuclear reactor outside a convention center in Washington, D.C.

The most important thing the nuclear community can do to support space nuclear applications is the same thing we must focus on for terrestrial nuclear science: developing the trust of the American public.

Americans are widely supportive of NASA, and space has long captivated our imaginations. Recently, the publicity surrounding the new U.S. Space Force and the popularity of commercial rocket launches have drawn the public eye skyward. We don’t need to convince people that space is important and exciting, but we do have a long way to go in promoting nuclear power to the public.
