In plain English

Sellafield Limited is buying nuclear-grade HEPA air filters (high-efficiency particulate air filters) for use across multiple nuclear decommissioning sites. Suppliers must design, manufacture, test, and deliver these filters to strict nuclear specifications, with orders placed as needed rather than one large bulk purchase.

What the buyer wants

• Design, manufacture, test, and deliver nuclear-grade HEPA filters in two separate lots (smaller basket and larger basket of different filter types) • Meet Sellafield Ltd's detailed technical specifications for all items produced • Carry out type testing to prove filters meet required standards • Provide filters on a call-off basis, meaning you supply as orders are placed, with no guaranteed minimum volumes

Lots

Requirements

What could rule a small business out: This contract is unsuitable for most small businesses: it requires nuclear industry accreditation, security clearance, specialist manufacturing capability for nuclear-grade components, extensive type testing facilities, and proven experience supplying to nuclear operators. The estimated contract value of £6.5 million indicates substantial scale and complexity.
