Details

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.

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this manufacturing & supply opportunity. Always verify the details on the official source.

Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
