Agreement could see Odin prototype microreactor built at Berkeley

Chiltern Vital Group has signed a letter of intent with Cambridge Atomworks to consider the construction of the prototype Odin microreactor on the Berkeley Green Science and Technology Park in Gloucestershire, England.

In September last year, a planning application was submitted for a new nuclear energy-focused facility on a brownfield site that was once part of the Berkeley nuclear power plant in south-west England. Planning and development consultancy Turley submitted the outline planning application for the proposal, which would feature nuclear and clean energy research and development facilities, on behalf of Chiltern Vital Berkeley (CVB), part of Chiltern Vital Group (CVG).

The site comprises a parcel of previously developed land which formed part of the wider Berkeley nuclear power station. It is currently occupied by the Gloucestershire Science and Technology Park, acquired by CVB in 2024, and has an established history for nuclear, employment and education uses. If approved, the development will offer up to 600,000 square feet (5.6 hectares) of new R&D, laboratory, office, manufacturing, and education facilities, creating up to 1,000 jobs.

CVB says it is in final-stage negotiations with multiple nuclear and energy technology companies wishing to locate on the Berkeley Green site.

Cambridge Atomworks has now announced that it has signed a letter of intent with CVG on building its prototype Odin microreactor on the site.

The Odin microreactor is described as “a low-pressure, molten-salt-cooled, solid-fuel fission reactor integrated with power conversion and heat rejection systems, enabling substantial and compact, standalone electricity supply without external connections”. Cambridge Atomworks plans to have an operational prototype by 2030………………………………………………………………………………………………………………………………
