FLEX reactor

The FLEX reactor is designed with simplicity in mind. It is small and modular, allowing components to be factory-produced and readily transportable, reducing on-site work, increasing speed of construction, and minimising overall costs. It is passively safe, so doesn’t need the engineered, redundant, active safety systems that add so much cost to conventional nuclear power.

The reactor has no moving parts and is fuelled for 20 years at a time, meaning that there is very little operator input and very low ongoing costs. It’s a simple device that produces heat when it’s needed and otherwise quietly idles.

Each reactor delivers 40 MW of thermal energy at 750°C. This heat is stored in MoltexFLEX’s GridReserve thermal storage tanks, so that the power plant can deliver three times the power when renewables alone cannot meet the market need for electricity.
