US construction firm Burns & McDonnell has entered into an agreement with BWX Technologies Inc to further the design and development of the BWXT Advanced Nuclear Reactor, which is being evaluated for deployment in Wyoming.

The Nuclear Industry Association has applied to the UK government for a justification decision for Rolls-Royce SMR's small modular reactor, a decision required for the operation of a new nuclear technology in the country. It marks the first ever application for justification of a UK reactor design.

US fusion energy developer Type One Energy has selected Canadian engineering firm AtkinsRéalis to develop the pre-concept design for its Fusion Pilot Plant, which will use stellarator technology to demonstrate its potential to generate clean, safe and affordable power from fusion energy.

Aalo Atomics has submitted a pre-application regulatory engagement plan with the US Nuclear Regulatory Commission for its Aalo-1 microreactor, detailing the planned pre-licensing application interactions with the regulator.

France's EDF plans to optimise the design of its Nuward small modular reactor design, focusing on existing and proven technologies. The move follows feedback from potential European customers in order to guarantee that project deadlines and budgets are met.

Innovative reactor developer Newcleo announced it has completed the preparatory stage set up by the French authorities for developers of small modular reactor projects to facilitate, secure and accelerate the review of licence applications.

Denmark's Copenhagen Atomics has signed a large-scale experimental collaboration agreement with Switzerland's Paul Scherrer Institute to conduct the first critical experiment on thorium molten salt reactors in Europe.

The UK's National Nuclear Laboratory has appointed engineering group Jacobs to help in the development of a high temperature gas reactor design that it is developing in partnership with the Japan Atomic Energy Agency.

The Russian environmental regulator Rosprirodnadzor has approved the plans for a BN-1200 fast sodium reactor at the Beloyarsk nuclear power plant.

The Swedish Energy Agency has granted SEK50 million (USD4.7 million) for a project led by researchers at Chalmers University of Technology in Gothenburg for the development of an entire Generation IV nuclear power system. The project also aims to rebuild national expertise in nuclear technology science.

The 184-tonnes section - the second of three - has been lifted into place for the lead-cooled fast neutron reactor under construction at the Siberian Chemical Combine site in Russia.

UK-headquartered innovative reactor developer Newcleo has signed a partnership agreement with the French Alternative Energies & Atomic Energy Commission (CEA) on the development of Newcleo's lead-cooled fast reactor.
