Cutting-edge nuclear technology projects across the UK have received government backing to help develop the next generation of nuclear reactors.

The funding will support early-stage innovation for six winning projects, helping attract private investment and supporting the creation of new, highly-skilled green jobs.

This £3.3 million funding through the Advanced Modular Reactor Research, Development and Demonstration (AMR RD&D) programme, will support the development of cutting-edge nuclear technology in the UK such as high temperature gas reactors (HTGRs), helping revolutionise the way the UK gets its energy.

The innovative projects being backed by the government include National Nuclear Laboratory Ltd in Cheshire, who are coordinating a UK-Japan team to design an innovative HTGR, and U-Battery Developments Ltd in Slough, for a study to determine the optimum size, type, cost, and delivery method for a U-Battery AMR suitable for demonstration in the UK.

The AMR funding represents another key step in the government’s plans to accelerate homegrown nuclear power to strengthen the UK’s energy security.

Energy Minister Greg Hands said: “This investment will help unlock the potential for new nuclear reactors in the UK, as we drive forward plans to boost clean, cutting-edge, homegrown technologies for our energy security, while driving down bills in the long term.”

£2.5 million in funding is going to six projects seeking to develop AMRs in the UK. These reactors use novel and innovative fuels, coolants, and technologies to generate high-temperature heat for industrial use, as well as electricity.

The AMR RD&D programme, part of the £385 million Advanced Nuclear Fund, focuses on developing HTGRs, with an ambition for a demonstrator by the early 2030s, as they optimise opportunities for decarbonising industrial heat to support the UK’s target of reaching net zero by 2050.

AMR technology could be a cost-effective solution for decarbonising industry, typically having higher temperature outputs than conventional reactors. The low carbon, high temperature heat from AMRs could be used for hydrogen production, process heat for industrial and domestic use, as well as electricity generation.

In addition, the government is providing up to £830,000 to the Office for Nuclear Regulation and the Environment Agency to develop their capability and consider innovative regulatory approaches to HTGRs.

This will help support the government’s plans to have a UK-based HTGR demonstration by the early 2030s. BEIS will work with the Nuclear Decommissioning Authority and their wider estate to explore how to leverage their knowledge, sites and operational experience to inform the development, deployment and operation of the demonstration and to support BEIS policy objectives in this area.
