Tender 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 the buyer

The UK Atomic Energy Authority is the central government body behind the UK's fusion energy programmes and tenders every opportunity above a low-value threshold. Opportunities and notices are published on the Central Digital Platform, also known as Find a Tender. Bidders access all tender documents through EU Supply, the authority's centralised platform. Much of this procurement flows through government frameworks, including the Crown Commercial Service. A quarterly procurement pipeline gives visibility of larger forthcoming opportunities. Two published charters, on the supply chain and on social value, set out the authority's approach to its suppliers.

Procurement spend from central entities makes up 66% of overall UK public spend.

Over the past 5 years, most of the UK Atomic Energy Authority's contract awards have been in IT services, software and information systems and industrial machinery.
