## Summary

The Expert Support and Alternative Solutions Framework awarded by Nuclear Waste Services Limited, focuses on providing specialised waste management services, particularly for radioactive-, toxic-, medical-, and hazardous waste. The procurement process, classified under CPV code 90520000, concluded with an active award on 21 April 2026. The procurement method employed was an open procedure above threshold, finalised with an estimated value of £14.5 million, although it is a zero-value framework agreement. The services cater to organisations holding a Waste Services Contract with NWS, targeting both NDA customers and non-NDA entities. This framework aims to deliver technical and professional waste services and develop alternative treatment solutions. Located in North West, United Kingdom, the contract spans from 1 March 2026 to 28 February 2030.

This tender provides ample opportunities for growth for businesses specialising in waste management, particularly those with expertise in handling challenging waste streams requiring comprehensive solutions. It is particularly beneficial for large businesses adept at providing technical testing, analysis, consultancy services, and waste treatment solutions, as it involves significant engagement across the radioactive waste management lifecycle. Companies capable of offering on-site support and development and delivery of alternative solutions are well-suited to compete. The awarded suppliers, including prominent entities such as Atkins Limited, Nuvia Limited, and NSG Environmental Ltd, represent a network of experienced organisations contributing to innovative waste management solutions. Organisations seeking involvement in strategic development or optimisation of waste management processes would benefit greatly from this multi-year agreement.

## Notice

Nuclear Waste Services (NWS), through its Waste Services line of business, will provide an Expert Support & Alternative Treatment Solutions (ESAS) service to both Nuclear Decommissioning Authority (NDA) and non-NDA customers. The ESAS Framework (estimated value of PS14.5m, although formally a zero-value agreement with no spend guaranteed) will be available to all NWS customers with a Waste Services Contract. The Framework includes: - On-site support; - Technical and professional waste services; - Enabling activities; - Development and delivery of alternative solutions (including pilots); - Research & Development; - Container and Package Quality. As the diversion of LLW from LLW Repository (nr Drigg, Cumbria) has become business as usual over the past 10 years and decommissioning programmes at customer sites have matured; the types of waste being managed through NWS frameworks has changed. NWS is seeing an increase in the number of challenging / problematic waste streams which require broader waste acceptance criteria and/or a range of specialist waste management advice/support. Customers often also require support higher up in the waste lifecycle / value chain, covering route development / optimisation, characterisation techniques and training of their internal resources. This trend is set to continue as further changes in decommissioning occur over the next decade. The ESAS Framework therefore supports NWS' mission and vision by providing access to an experienced pool of expert resources and fit for purpose responsive solutions. The Framework provides access to contractors with knowledge and understanding across the full radioactive waste management lifecycle and the ability to operate and execute work and provide support at any stage of the lifecycle. The Framework will be for use by organisations that either currently hold, or may in future enter into, a Waste Services Contract with NWS. These organisations include private sector bodies, plus public sector bodies that fall into one or more of the following categories (please see attachment).
