Low Level Waste Repository (LLWR) Vault Optimisation and Capping Delivery

Descriptions

Nuclear Waste Services (NWS) operates the Low-Level Waste Repository (LLWR) Site in West Cumbria on behalf of the Nuclear Decommissioning Authority. The LLWR Site is the national disposal facility for Low Level Waste (LLW) arising from the nuclear industry and wider industries, such as medical and defence. Protecting and developing the Repository’s radioactive waste disposal capability is a long-term programme of works, over the next 100+ years, that will provide future disposal facilities and protection of people and the environment from the disposed waste through to closure of the Repository Site. In the shorter term, over the next 15 years, the focus is on installing closure engineering works for long-term environmental protection from the wastes currently disposed of in Vault 8 and the adjacent legacy disposal trenches as well as constructing additional disposal capacity in the form of new LLW vaults. NWS is seeking supply chain support to deliver significant Civil Engineering design and build capability for; • the optimised preliminary and detailed design for the next phase of disposals at the Repository in line with the Site’s Environmental Permit and Environmental Safety Case including Vault 9a, Leachate Management System and base slab for HHISO temporary warehousing. • Capping of the existing legacy disposal vault (Vault 8) and adjacent section of the legacy disposal trenches. • Construction of the future LLW disposal Vaults and Leachate Management System (as per detailed design above). • Closure and cap Design for the currently operational Vault 9. • Closure and partial Cap construction for Vault 9. (as per design above). The route to market decision will be based on market feedback and the ongoing development of the NWS procurement documents.
