Nuclear 'super cluster' planned in Gloucestershire as sale of 40-acre site goes through

A nuclear "super cluster" is set to be established on the site of a former nuclear power station in Gloucestershire, after the sale of the plot by South Gloucestershire and Stroud College goes through.

The £6.5m acquisition of the 40-acre science park in Berkeley by Chiltern Vital Group (CVG) paves the way for the development of cutting-edge nuclear technology and a low-carbon energy hub.

The site, which previously housed one of the world's first civil nuclear power stations, is poised to become a centre for innovation in small modular reactor (SMR) technology.

According to the IAEA, Small modular reactors are advanced nuclear reactors that have a power capacity of up to 300 MW(e) per unit, which is about one-third of the generating capacity of traditional nuclear power reactors.

Due to their smaller footprint, SMRs can be located in areas that aren't suitable for larger nuclear power plants. Prefabricated SMR units can be manufactured offsite and then transported and installed on location, making them more cost-effective to build than large reactors. 

The government is expected to announce a technology provider soon, with Rolls Royce SMR currently in the final approval stage with the Office for Nuclear Regulation.

The project aligns with the UK's commitment to achieving net-zero emissions and ensuring energy security.

Kevin Hamblin, CEO of South Gloucestershire and Stroud College (SGS), which sold the site, said: "CVB can now invest in the site to support research, development and skills training around new nuclear, AI and low carbon businesses.

"CVB and their partners will bring significant new investment and work opportunities for the region; and for SGS it will mean the college plays a very prominent role to support the teaching of new skills for many years to come."

The planned super cluster will build upon the site's rich nuclear heritage, which includes its role in developing the UK's nuclear fuel programme.

The site was formerly one of the first civil nuclear power stations in the world and was home to a Magnox reactor from 1962 to 1989.
