    Brief

    The UK National Nuclear Laboratory (UKNNL) is establishing an Open Framework to supply Nuclear Technical Services. The framework will operate from September 2026 to September 2030, with an optional 4-year extension to July 2034. Key Framework Details: - The framework will reopen at least once during the initial 3-year period and at least once more during any extended 5-year term, as required by the Procurement Act 2023 - Additional reopenings may occur up to twice annually based on supply/demand changes, requirement updates, or structural modifications - Suppliers may update their technical and commercial proposals at each reopening or retain their previous submission Call-off Contract Options: Contracts can be awarded through mini-competition or direct award, with pricing structured as either fixed-cost or cost-reimbursable arrangements. Mini-Competition Process: - Conducted via e-tender portal with all suppliers on the applicable lot invited - Restricted to one lot per competition - Suppliers may offer discounted rates but cannot exceed their original framework submission pricing - Evaluation weighted across: Pricing (5-90%), Technical (5-90%), and Social Value (5-90%) Direct Award Options: 1. Award to highest technically ranked supplier capable of delivering the required services 2. Desktop Calculator method: Combines technical scores and pricing using a formula to identify the Most Advantageous Tenderer, with weighting between Pricing (5-95%) and Technical (5-95%) determined by call-off requirements Suppliers unable to fulfill role requirements, clearance levels, or timeframes will result in progression to the next highest-ranked qualified supplier.
