Rosatom subsidiary Atomflot has accepted delivery of the Sibir, its newest nuclear-powered icebreaker. The twin-reactor vessel was officially handed over by the Baltic Shipyard which built it.

Russia's newest nuclear-powered icebreaker, the Sibir, has left the Baltic Shipyard and headed into the Gulf of Finland for sea trials. Two more identical ships are under construction at the shipyard near Saint Petersburg.

Australia is to acquire nuclear submarines as the first initiative under a new enhanced trilateral security partnership announced by the leaders of Australia, the UK and the USA. The submarines are to be built in Australia, but the country is not seeking to acquire nuclear weapons or establish a civil nuclear capability, Prime Minister Scott Morrison said.

The UK has launched a consultation on proposed regulations for nuclear-powered ships that would enable UK-flagged vessels to use the power source and international vessels to visit its ports. "The UK is committed to enabling the adoption of new technologies that manufacturers and ship owners may choose to meet legal requirements relating to air pollution and greenhouse gas emissions, and therefore will establish a regulatory framework that will support nuclear-powered ships as an alternative fuel option," said the UK Maritime & Coastguard Agency.

Molten salt reactor technology has the potential to revolutionise the commercial shipping industry by making the largest ships faster, cleaner and more efficient, Core Power Chairman and CEO Mikal Bøe said in an interview with ¶¶Òõ´«Ã½ÔÚÏß Nuclear News. The goal is initially to power floating production of hydrogen-derived green fuels for a vast fleet of smaller vessels and, once licensed and approved, eventually to provide onboard electric propulsion power for large ships.

Three reactor design concept proposals for a nuclear thermal propulsion system for deep space missions have been selected by the US National Aeronautics and Space Administration and the Department of ¶¶Òõ´«Ã½ÔÚÏß. The reactor will be a critical component of a nuclear thermal engine, which would utilise high-assay low-enriched uranium fuel.

Ultra Safe Nuclear Technologies - a subsidiary of Ultra Safe Nuclear Corporation - is providing "critical support" to both prime contractors in the first phase of the Demonstration Rocket for Agile Cislunar Operations programme to develop a nuclear thermal propulsion system for cislunar operations. USNC-Tech is the only company participating in both tracks of the programme.

The US Defense Advanced Research Projects Agency has awarded contracts for the first phase of its Demonstration Rocket for Agile Cislunar Operations programme to demonstrate a nuclear thermal propulsion system above low Earth orbit in 2025. General Atomics will carry out reactor development work, while Blue Origin and Lockheed Martin will develop spacecraft concept designs.

The US Department of ¶¶Òõ´«Ã½ÔÚÏß has awarded BWXT Nuclear Operations Group two contracts worth a total of USD35 million. The first is for the recovery and conversion of uranium, while the second is for the completion of a new research reactor fuel line at its Lynchburg, Virginia facility.

The US Administration has issued a new directive on the use of nuclear power and propulsion in space. Space Policy Directive-6 establishes high-level goals, principles, roles and responsibilities, and a supporting roadmap demonstrating the nation's commitment to the safe, effective and responsible use of space nuclear power and propulsion systems.

The US government yesterday announced the release of the National Space Policy, which advocates for developing and deploying nuclear power and propulsion systems on US space missions. The document specifies who, or which government agency, is responsible for various aspects of their development and deployment.

Russia's new nuclear-powered icebreaker, Arktika, today completed its first operational voyage - piloting the Siyaniye Severa dry cargo ship to the entrance of the Gulf of Ob in the Russian Arctic, Russian state nuclear corporation Rosatom has announced.
