Spherical Tokamak for Energy Production

Spherical Tokamak for Energy Production (STEP) is a United Kingdom programme to design and build a prototype fusion power plant based on a spherical tokamak configuration. The programme is led by UK Fusion Energy Ltd., a wholly owned subsidiary of the UK Atomic Energy Authority (UKAEA) Group. STEP aims to demonstrate net electricity generation from fusion and support the development of a commercial fusion industry in the UK by around 2040.
