A coated particle fuel for nuclear thermal propulsion applications, fabricated by TRISO-X LLC, has undergone testing in extreme conditions representing those experienced in space.

The leaders of Australia, the UK and the USA have outlined the phased approach through which Australia will acquire nuclear-powered submarines through the Australia-United Kingdom-United States (AUKUS) enhanced security partnership.

Bangor University in Wales will develop a nuclear thermal fuel system to support deep space exploration with funding provided by the UK Space Agency. It is one of eight projects receiving a total of GBP1.6 million (USD1.9 million) in funding through the agency's Enabling Space Exploration fund.

Nine South Korean organisations have signed a memorandum of understanding to cooperate on the development and demonstration of ships and offshore systems powered with small modular reactors. The partners will also develop marine systems and the production of hydrogen using molten salt reactors.

The agreement signed between the Baltic Shipyard and Atomflot is for two more nuclear-powered icebreakers as part of Russia’s Project 22220.

The USA's National Aeronautics and Space Administration and the Defense Advanced Research Projects Agency are to collaborate on developing and demonstrating a nuclear thermal rocket engine in space by 2027.

The UK Space Agency and the National Nuclear Laboratory are to collaborate on the world's first space battery powered by americium-241. The isotope will be extracted from used nuclear fuel stored at the Sellafield site in Cumbria.

The nuclear powered icebreaker, the Ural, is the third of Russia's Project 22220 vessels built at the Baltic Shipyard. Its first working voyage is to the Ob-Yenisei region of the Kara Sea.

A new nuclear powered icebreaker, the Ural, has completed factory sea trials lasting more than two weeks. Ural is the third of Russia's Project 22220 vessels built at the Baltic Shipyard.

The American Bureau of Shipping has announced it is to research barriers to the adoption of advanced nuclear propulsion on commercial vessels under a research contract awarded by the US Department of Energy. The organisation is also supporting separate research into molten salt reactors.

ZiO-Podolsk, part of the machine-building division of Rosatom - Atomenergomash, has manufactured and shipped the second RITM-200 reactor for the new generation icebreaker Yakutia, part of Project 22220.

The International Atomic Energy Agency is already working with Australia on the "complex" issue of ensuring nuclear safeguards in relation to its proposed acquisition of nuclear-powered submarines under the trilateral AUKUS partnership, the organisation's Director General Rafael Mariano Grossi said today.
