Description
The following summary is not intended as a complete or definitive specification of the requirement. A purpose of this engagement is to seek information from the market to help refine our understanding and aid the development of a future specification. UKIFS is seeking experts to support the design and development of a thermal storage system that integrates with the STEP power cycle. While the power cycle is designed to efficiently integrate heat from the tokamak device during a high power steady state scenario, the power cycle and cooling systems must also be highly flexible to adapt to uncertain prototypic operations e.g. the systems must have the ability to switch on and off and ramp up and down at the start and end of operational periods. Significant thermal power will be generated from the tokamak device during the ‘rapid density rise phase’ of the reactor plasma ramp up, lasting a few minutes. This is an effective ramp of 2GWth generated from the tokamak during these few minutes. To manage this very immediate and sudden generation of heat from the tokamak, a minimum amount of thermal storage will be needed to increase the thermal inertia of the primary coolant loops, allowi…
