UKNNL is establishing an Open Framework to support with the supply of Nuclear Technical Services for the United Kingdom National Nuclear Laboratory. The framework will run from September 2026 until September 2030 with the option to extend the framework by a further 4 years, until July 2034. The Framework will reopen once within the first 3-year period, and UKNNL will open it again at least once in the remaining 5-year contract term as required under Regulation 49 of the Procurement Act 2023. UKNNL may opt to open the framework for applications earlier than required, although not likely to be ever more than two times per year. Re-opening may be in relation to the framework agreement in its entirety or in relation to specific lots. Earlier re-opening could be triggered by a range of factors, which may include but are not limited to: Supply & demand changes, Changes to requirements, Changes to framework lotting structure, Changes to rate card structures, Changes to qualitative assessment, Changes to framework management, Addition of new framework lots, Changes to demand, volumes, values and geographical coverage. Suppliers are permitted to amend their technical and commercial response at each re-opening or can choose to allow their previous submission to be considered. The framework has the ability to award contracts through mini competition or direct award. Call-off contracts can be either fixed cost or cost reimbursable. Mini-Competition Where mini-competition is used, this is to be via the e-tender portal and must include all suppliers on the applicable lot. Each mini competition will be restricted to only one Lot. At mini-competition, suppliers can be asked to re-price and may offer discounted rates if they choose to, but may not charge more than the pricing which was submitted at the latest round of framework qualification. Should requirements at call-off not have been priced at point of framework creation, mini-competition should be held allowing all suppliers in the applicable Lot to price, accordingly, providing the additional requirement fits within the overall subject matter of the applicable Lot. Mini-competition criteria must not repeat qualification questions. The evaluation criteria must however comprise of the following, with weighting allowances adhered to: Evaluation Criteria Range Pricing 5-90% Technical 5-90% Social Value 5-90% Mini competitions can be ran using both the Open Procedure and the Competitive Flexible Procedure under the Procurement Act 2023, where the call-off is above threshold. Direct Award There are two direct award mechanisms under this Framework Agreement: (1) Direct award to the highest technically ranked supplier. (2) Direct award using the desktop calculator Direct award to the highest technically ranked suppliers Admittance to the framework is via a 100% ... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/open-framework-for-nuclear-technical-services-ocds-h6vhtk-0694f1) ## Lots (10) ### Lot 1: Lot 1 - Health Physics and Radiological Protection Advisor - **Lot id:** `1` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0001: Lot 2 - Human Factors - **Lot id:** `LOT-0001` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0002: Lot 3 - Radiological & Chemotoxic - **Lot id:** `LOT-0002` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0003: Lot 4 - Criticality Safety and Shielding - **Lot id:** `LOT-0003` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0004: Lot 5 - Nuclear Safety Case - **Lot id:** `LOT-0004` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0005: Lot 6 - Fire Safety (Nuclear and Conventional) - **Lot id:** `LOT-0005` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0006: Lot 7 - Environmental - **Lot id:** `LOT-0006` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0007: Lot 8 - Quality and Assurance - **Lot id:** `LOT-0007` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0008: Lot 9 - Security - **Lot id:** `LOT-0008` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/07/2030 - **Renewal published:** yes ### Lot LOT-0009: Lot 10 - Multi-Disciplinary Lot - **Lot id:** `LOT-0009` - **Status:** complete - **CPV codes:** 71350000, 73210000, 90714500, 98113100 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £10,000,000 - **Contract Period:** 27/07/2026 to 27/06/2030 - **Renewal published:** yes ## Awards & Winning Suppliers (10) - **Award:** Lot 1 - Health Physics and Radiological Protection Advisor (active) - Award id: `1` - Supplier(s): **AMENTUM CLEAN ENERGY LIMITED, AtkinsRéalis, CYCLIFE UK LTD (+3 more suppliers)** - Supplier identifiers: `GB-FTS-180459`, `GB-PPON-PLLV-1772-YDYN`, `GB-FTS-132958`, `GB-FTS-12562`, `GB-FTS-115505`, `GB-FTS-183962` - Value: £12,000,000 (inc.
