The Nuclear Regulatory Commission has accepted for review the Tennessee Valley Authority’s construction permit application for a BWRX-300 small modular reactor at its Clinch River site in Tennessee. The NRC expects to complete its review by December 2026.

The Manhattan Project is usually considered to have been initiated with Albert Einstein’s letter to President Franklin Roosevelt in October 1939. However, a lesser-known document that was just as impactful on wartime nuclear history was the so-called Frisch-Peierls memorandum. Prepared by two refugee physicists at the University of Birmingham in Britain in early 1940, this manuscript was the first technical description of nuclear weapons and their military, strategic, and ethical implications to reach high-level government officials on either side of the Atlantic. The memorandum triggered the initiation of the British wartime nuclear program, which later merged with the Manhattan Engineer District.

Helical Fusion, a private fusion start-up based in Japan, announced it has closed its first round of venture capital financing, securing ¥2.3 billion ($15.6 million) in funding. According to Helical Fusion, this brings the company’s total capital investment—including grants and loans—to ¥5.2 billion ($35.3 million).
Ronald E. Evans, the command module pilot for Apollo 17, performed a deep-space extravehicular activity (EVA) to retrieve a film canister during the mission’s return to Earth. At about 160,000 miles from Earth, it was the most distant spacewalk ever conducted in deep space under full-spectrum GCR. (Photo: NASA)
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

As the U.K. government looks to finalize investment decisions for the construction of the Sizewell C nuclear power plant this summer, France’s state-owned EDF has announced plans to take a 12.5 percent stake in the project and commit up to £1.1 billion ($1.5 billion) in funding.

Chris Wagner has more than 40 years of experience in nuclear medicine, beginning as a clinical practitioner before moving into leadership roles at companies like Mallinckrodt (now Curium) and Nordion. His knowledge of both the clinical and the manufacturing sides of nuclear medicine laid the groundwork for helping to found Eden Radioisotopes, a start-up venture that intends to make diagnostic and therapeutic raw material medical isotopes like molybdenum-99 and lutetium-177.

The International Atomic Energy Agency has initiated a coordinated research project that will combine an “innovative, non-invasive, and scalable nuclear technique”—gamma-ray spectrometry (GRS)—with drones and satellite imagery to gather and analyze data that can reveal the quality of soil on agricultural lands around the world.

The Nuclear Regulatory Commission has whittled down the timeline for reviewing TerraPower’s construction permit application for Kemmerer Power Station Unit 1 in Wyoming. Announcing a new, more aggressive schedule, the NRC said it aims to complete its review by the end of 2025, eight months earlier than originally planned.

Westinghouse Electric Company announced that it has signed a $180 million contract with the ITER Organization for the assembly of the vacuum vessel for the fusion reactor being built in southern France. Designed to demonstrate the scientific and technological feasibility of fusion power, the ITER tokamak will be the world’s largest experimental fusion facility.

Global Laser Enrichment announced that it has submitted its safety analysis report to the Nuclear Regulatory Commission for the planned Paducah Laser Enrichment Facility (PLEF). This follows GLE’s December 2024 submission of the plant’s environmental report, now completing GLE’s full license application for NRC review.
