UK Public Sector Contracts & Tenders

Contract to provide consultancy services specifically for the development of Security & Safeguards cases, supporting the GDF design & development process.

This is a procurement for a Disposability Assurance Framework. Disposability Assurance is a key mechanism for risk mitigation across the NDA Group, enabling the packaging and interim storage of radioactive waste. The Framework will consist Three Suppliers across four Bundles, Bundles A to C being direct award and Bundle D being mini-competition (further details in the ITT documentation). Organisations are invited to submit their ITT responses via NWS's Atamis system (https://atamis-2464.my.site.com/s/Welcome), which can be accessed against Record Ref C6116 Disposability Assurance Support Framework 2024 which is listed within the 'Find Opportunities' area on the portal.

The Integrated Design and Engineering Framework agreement seeks to provide NWS with a multidisciplinary <br/>vehicle to undertake design for works at the Repository Site and where required, resource enhancements <br/>directly into NWS, in client design management roles. Activities will be managed through Project Orders <br/>awarded as a call-off from the Framework

The Activities are predominantly the delivery of key development activity for the Client programmes and operations including:<br/>• Geological Disposal Facility Programme (GDF Programme): Site characterisation activities to enable the Geological Disposal Facility (GDF), including the drilling of deep boreholes to characterise potential geology to hosft a GDF, which falls within the definition of a “nationally significant infrastructure project”. <br/>• Near Surface Disposal Programme (NSD Programme): Near Surface Disposal activities. <br/>• Ongoing operation and development of the licenced Low Level Waste Repository at Drigg, including capping of vaults.

The Integrated Site Works Framework (ISWF)seeks to undertake work which supports the delivery of ongoing site works, asset refurbishment and projects relating to general infrastructure and operations – removal of existing assets and replacing with new to facilitate future missions of the Low Level Repository LLWR) Site in Drigg, Cumbria.

The NWS criticality safety programme covers all materials currently considered in the inventory that may require disposal in any of the facilities (LLWR, GDF or other options). This includes low level waste (LLW), intermediate level waste (ILW), high level waste (HLW), spent fuels, uranium (particularly depleted, natural and low enriched uranium, DNLEU) and plutonium. NWS (and predecessor organisations) has commissioned a significant amount of work previously to build the knowledgebase in this area, again with a significant focus on the GDF disposal needs. However, the GDF programme is ongoing and continuous review and update of other disposal options is undertaken and therefore further criticality safety work will be required to continue to support the respective safety cases. To support the delivery of criticality safety scope, NWS wish to establish a contract for the provision of criticality safety services. ITT documents are available on Atamis: https://atamis-2464.my.site.com/s/Welcome

This is a procurement for technical requirements and criticality safety programmes to develop the GDF.

Nuclear Waste Services Limited (NWS) currently operates the Low Level Waste Repository (LLWR) near the village of Drigg in Cumbria. The purpose of the LLWR is to manage and dispose of low level radioactive waste (LLW).

Nuclear Waste Services (NWS) would like to notify suppliers of future requirements and engage with the market to understand what it can provide with regards laboratory services for the investigation the impact(s) of the expected chemical environments of the MMG and Ancholme group geological settings on the corrosion behaviour of carbon steel HHGW container materials.

Framework to deliver Treatment & Conditioning services (including incineration, supercompaction and chemical treatment). NWS are issuing two (2) bulk orders as initial call-off contracts, which are optional for Tenderers to bid for, these include: - Bagged Combustible Bulk Order - the thermal treatment of up to 1800m3 per year of soft combustible waste from across the SL Site. - Bulk Combustible Bulk Order - the thermal treatment of up to 52 half-height ISO containers per year of bulk combustible materials from across the SL site.

The ThermoChimie project (Thermo-Chimie (version applicative 4.4.0)) is a thermodynamic database development project, co-funded by Nuclear Waste Services, NIRAS-ONDRAF, and Andra. A robust, traceable, exhaustive, and dependable thermodynamic database is essential for underpinning a future Environmental Safety Case for the surface, near-surface or deep geological disposal of radioactive waste, as well as to perform a range of sensitivity and scoping calculations in support of ongoing research activities. Phase 4 of the ThermoChimie project is planned to start in February 2026. The ThermoChimie Phase 4 Framework has the overall objective of providing both specialist and non-technical support resource to the consortium, in the form of a range of desk-based and experimental data generation/selection activities. Outlined activities are in support of the four key project success factors: (i) database traceability, (ii) consistency, (iii) east of use, and (iv) exhaustivity.
