A World Safe From Firestorms is a World Safe from Nuclear Winter

Nuclear winter is the theory that severe and prolonged global climatic cooling will happen after a large-scale nuclear war. This assumes that fires can inject soot into the stratosphere. This would block some direct sunlight from reaching the surface of the Earth. This would then lead to widespread crop failure and famine. Nuclear-winter scenario researchers …

Nuclear War Analysis

The current nuclear arsenal will not kill all humans and the pattern of nuclear explosions for a nuclear war between the largest nuclear powers will not destroy civilization, let alone kill all people or even half of all people. The greatest risks from a total nuclear war are from fire and starvation and not from …

Billionaires $1.8 Funding for Commercial Fusion Maybe by 2030

Commonwealth Fusion Systems (CFS) announced it has closed on more than $1.8 billion in Series B funding to commercialize fusion energy. This money will be used construct, commission, and operate SPARC, the world’s first commercially relevant net energy fusion machine. They will also start work on ARC, the first commercial fusion power plant, which includes …

China Megawatt Space Nuclear Reactor

China is developing a megawatt nuclear reactor for moon and Mars missions according to the South China Morning Post. Jiang Jieqiong, a professor with the Chinese Academy of Sciences’ Institute of Nuclear Safety Technology, has suggested that the nuclear reactor could use a foldable structure – similar to an umbrella – to increase the surface …

Criticality for Both High Temperature Pebble Bed Reactors

Both nuclear reactors of the High-Temperature Gas Cooled Reactor-Pebble-bed Module (HTR-PM) at the Shidaowan plant in China’s Shandong province have reached criticality for the first time. The HTR-PM has two 250 MW thermal reactors that drive a single 210 MWe turbine. Commercial 600 MWe pebble bed reactors (6×250 MWt, total 655 MWe) will follow. the …

France Building Nuclear Reactors Again

French President Emmanuel Macron said France will build six new nuclear reactors. This will keep France’s energy costs at a “reasonable” level and reduce dependence on imports. France will save energy and invest in domestic carbon-free energy production. Nuclear power was at the heart of Macron’s France 2030 plan for re-industrialization which was announced last …

Full Modular Nuclear Reactor Mockup

A full-scale mock-up of the main vessels of the U-Battery advanced modular reactor (AMR), by U-Battery and Cavendish Nuclear, has demonstrated how the reactor can be built using modular techniques. The mock-up includes the reactor vessel, the intermediate heat exchanger vessel, and the u-shaped connecting duct, began in February 2020, Threlfall said at an event …
