The U.K. government has just published Towards Fusion Energy: The UK Government’s Fusion Strategy, which sets out the goal of the United Kingdom's moving from “a fusion science superpower to a fusion industry superpower,” with a prototype fusion power plant being built in the country by 2040.

While a slightly ambitious plan, there are now about 20 startup companies working to achieve a Wright brothers’ moment in fusion sooner than that. This includes Commonwealth Fusion Systems, which is aiming for a working fusion power plant by 2030 and is the subject of Rivka Galchen’s October 4 New Yorker article, “Can Nuclear Fusion Put the Brakes on Climate Change?”

Only a few of the more than 3,000 radioisotopes that scientists have synthesized in the laboratory are regularly used in diagnostic or therapeutic medicine. One significant barrier to the development of new medical radioisotopes is the difficulty of gaining access to radionuclides during the early stages of development and research. PRISMAP is a new medical radionuclide program designed to streamline that access for medical research in the European Union and the United Kingdom.

A high-temperature superconducting magnet reached and maintained a magnetic field of more than 20 tesla in steady state for about five hours on September 5 at MIT’s Plasma Science and Fusion Center. Not only is the magnet the strongest high-temperature superconducting (HTS) magnet in the world by far, it is also large enough—when assembled in a ring of 17 identical magnets and surrounding structures—to contain a plasma that MIT and Commonwealth Fusion Systems (CFS) hope will produce net energy in a compact tokamak device called SPARC in 2025, on track for commercial fusion energy in the early 2030s.

In the aftermath of a devastating explosion in the port of Beirut, Lebanon, in August 2020, an International Atomic Energy Agency team visited the country at the government’s request and found no evidence of artificial radionuclides and no increase in radiation levels. The powerful blast, which was caused by an explosion of improperly stored ammonium nitrate, killed more than 200 people and leveled numerous buildings while leaving other buildings standing with possible structural damage. The IAEA recently announced that a different team of experts has traveled to Lebanon with a new mission: to assist the nation in the use of non-destructive testing (NDT) to check the structural soundness of buildings that were impacted by the explosion.
