The Trump administration is advancing a plan to supply Cold War-era plutonium from dismantled nuclear warheads to companies that would convert the material into fuel for nuclear power plants. The proposal has drawn debate and unease among experts and observers, who are weighing the potential benefits of reusing weapons-grade material against safety and proliferation concerns.

The HBO Max series Lanterns is drawing attention after one of its writers said altering established DC canon is 'like handling plutonium,' but argued there is 'no fun and creativity' in playing it safe. The remarks have fueled discussion among fans about how far the show will go in reworking Green Lantern mythology for television.

Scientists reported additional talks covering a range of nuclear topics, including plutonium production in fast reactors, the effects of nuclear war on water cycles, measurements at nuclear weapon test sites, remote detection of tests, and the links between sustainability and nuclear non-proliferation. The sessions connect reactor technology and weapons policy with climate and environmental research.

A new training facility at the Savannah River Site in South Carolina is advancing efforts to expand plutonium pit production, a core component of the US nuclear weapons stockpile modernization programme. The facility will prepare workers for pit manufacturing work, which the National Nuclear Security Administration also plans to scale up at Los Alamos. Local coverage highlights the site's growing role in the national nuclear complex.

IEEE Spectrum takes readers inside the reactor that produced the plutonium used in the "Fat Man" bomb dropped on Nagasaki in 1945. The feature offers a rare look at the historic site where weapons-grade material was first manufactured at scale, recounting its role in the Manhattan Project and its place in nuclear history.
