New fission reactor designs, smaller or using new coolants and fuels, meant to be cheaper, safer and faster to build.
Why pilot: Four advanced test reactors reached criticality by July 4, 2026, and TerraPower began building Kemmerer Unit 1 under an NRC permit. Jul 25, 2026This week: NASA's SR-1 Freedom project achieved progress on its nuclear power module.
Dots under a month: dated events tracked here that month.
Destined for Mars and beyond, NASA’s Space Reactor-1 (SR-1) Freedom will be humanity’s first fission-powered spacecraft to travel outside Earth’s orbit. Announced during NASA’s “Ignition” event, this mission will demonstrate nuclear electric propulsion in deep space, and progress is underway on its
SEC Form 8-K, items 1.01, 3.02.
On 23 September, Italy’s Senate passed legislation establishing a framework for the development of nuclear fission and fusion energy in the country. The post Italy Passes Legislation in Support of Nuclear Fission and Fusion Energy appeared first on Fusion Industry Association .
This week, Italy’s Parliament approved a bill on sustainable nuclear power, giving the Government authority to define the regulatory frameworks for nuclear fission and fusion energy. The frameworks will cover the full lifecycle of facilities and includes plans for a National Program for Nuclear Prod
