In plain English

UK Fusion Energy Ltd requires the detailed design and manufacture of a scaled-down FALCON valve prototype for the STEP Prototype Powerplant. No special requirements are stated.

Description from the notice

The scope of this work is to provide the detailed design and manufacture of a scaled down Fast Acting Low Conductance valve (FALCON) prototype which will be used to safeguard the proposed exhaust vacuum pumping technology against Disruption mitigation or sudden massive air ingress events for the STEP Prototype Powerplant (SPP). The scope of work includes the detail design and build of a scaled down prototype, which includes everything within the Vacuum Gate/Isolation valve casing (including the casing itself), mainly the actuation mechanism and the seals required to maintain both the operation of the isolation valve and the vacuum integrity of the process gas line. The fast-acting nature of the valve requires it to reach its defined ‘close’ position within 37.5 ms.
