What is being bought

Published requirement description

A system at UKAEA includes a permeator vessel consisting of a heated palladium alloy membrane for the purpose of hydrogen gas purification. The permeator membrane has deteriorated over time and has reached a point where the vessel needs to be replaced. A spare permeator vessel was not procured with the installed one and the original manufacturer is no longer capable of supplying a like-for-like replacement. UKAEA is seeking market engagement with suppliers capable of designing and supplying a replacement permeator vessel. The engagement is intended to understand market capability, indicative solutions, lead times, delivery risks and innovation opportunities.

About this data
  • Estimates, labelled. The price range, possible competitors and earlier-work matches are our estimates from past awards, not published facts, win chances or price advice. The buyer’s own record and the wider market are shown apart, never mixed.
  • Source. Official UK public procurement notices (Find a Tender and Contracts Finder), reused under the Open Government Licence v3.0, updated through the day and rebuilt nightly. Not every figure uses both feeds, and each one shows how many records it rests on: see the methodology. Spotted something wrong? Tell us.
