UK to develop advanced nuclear technologies

The UK Government’s Advanced Nuclear Framework outlines investment and innovation routes in the sector.

The Framework aims to stimulate private investment in nuclear technology innovations across the country.

A 'concierge-style' service will help developers understand requirements around UK planning, regulation and fuel, as well as enabling them to crowd-in private investment. The government believe this provides a clear route to market and support to accelerate credible projects that meet essential readiness criteria.

The government also states that advanced nuclear technologies, including advanced, small and micro modular reactors, can be manufactured quickly and cost-effectively in factories, which will help to create skilled jobs.

Commercial, private-sector deals between the UK and US companies include plans for X-energy and Centrica to build 12 advanced modular reactors in Hartlepool, as well as plans for Holtec, EDF, and Tritax to build small modular reactors (SMRs) at the former coal-fired Cottam power station in Nottinghamshire. The latter will provide power to data centres on the site.

TerraPower is also working with engineering firm KBR on potential deployment of its Natrium advanced reactor technology in the UK.

These investments come alongside the government’s greenlighting of the Sizewell C project in Suffolk and Wylfa SMRs in North Wales – the first SMRs in the country.

Developers can submit proposals using the Advanced Nuclear Framework to join the pipeline from March this year.

These will be assessed by experts in government and Great British Energy – Nuclear, according to key criteria such as technology status, developer capability and financing plans.

Successful applicants will receive government endorsement, as well as revenue support and risk protections, but will be expected to be privately financed.

Projects can also approach the National Wealth Fund to act as a catalytic investor and help derisk further private investment if they meet the investment criteria.

The Nuclear Decommissioning Authority is releasing surplus land for clean energy projects, with opportunities at Chapelcross in Scotland, Pioneer Park in Cumbria and Trawsfynydd in Wales.
