UK7 - Contract Details Notice
Summary of the contracting process

Sellafield Limited commissioned an upgrade to the flask-loading door on a milling machine used to maintain nuclear fuel flasks. The work is to replace or upgrade the existing arrangement with a compliant, interlocked internal sliding door. This is a specialist engineering requirement in a nuclear-fuel maintenance setting, rather than general door installation. The recorded service classification is hazard protection and control consultancy services (CPV 71317000). Delivery is in the United Kingdom; no more specific delivery place is identified in the procurement details.

The procurement is complete and the contract is active. Sellafield Limited used a direct award below the applicable threshold, without competition. One lot was awarded to Seymour Engineering Ltd. The contract was signed on 19 August 2026 and runs from 19 August 2026 to 31 March 2027. Its value is £41,112 excluding VAT (£49,334.40 including VAT). The recorded award basis is the requirement to upgrade the flask-loading door; no separate scored evaluation criteria are stated. The arrangement covers the specified machinery upgrade to provide a compliant interlocked internal sliding door.

For a future requirement of this kind, a credible supplier would need engineering capability to modify or replace industrial machine doors and integrate interlocks, with a clear understanding of the compliance and safety demands of equipment used in nuclear-fuel flask maintenance. Suppliers would need to demonstrate that their solution supports safe, reliable operation of a crucial machine, and can be delivered within an operational nuclear-site environment. This is a focused, single-machine engineering requirement rather than a large multi-lot programme. The buyer used a direct award without competition for this contract, so the selected supplier’s delivery is an example of the type of specialist engineering solution Sellafield required.
