Our Fusion Technology team is taking the UK’s fusion expertise into the age of power plant delivery. We enable industrial partners to test prototype components in the conditions found inside fusion reactors – getting a head start in the commercialisation of fusion energy.

We offer a suite of testing facilities and capabilities for advanced engineering and manufacturing in the UK fusion industry and beyond.

Many of the facilities are already operating and more are being developed. Facilities are located at complementary UKAEA sites at Culham Campus and the Fusion Technology Facility at the Advanced Manufacturing Park at Waverley, near Rotherham.

Tests at the Fusion Technology Facilities


UKAEA Fusion Technology can assist UK engineering companies in:

  • Winning contracts on international fusion projects
  • Contributing to the UK’s STEP power plant design project
  • Trialling technologies for the wider nuclear industry and other related areas

Fusion Technology capabilities

UKAEA test rigs can validate fusion components under combined thermal, mechanical, hydraulic and magnetic loads.

Programme areas include:



CHIMERA is a unique component loading machine, designed to test component prototypes in the simultaneous extreme temperature, heat flux and electromagnetic environment representative of fusion power reactor conditions.
