MOx Fuel Line

The current Fuel Line located in NNL’s Central Laboratory was designed and installed in the mid-2000’s in Area 400 to provide R&D support to SMP, which utilised the Short Binderless Route for producing MOx. However, the Fuel Line was never fully commissioned and has remained in a state of Care and Maintenance since then. NDA is responsible for the current civil plutonium stockpile and is currently considering options for plutonium disposition including reusing the material within new MOx fuel or immobilising within an inert matrix suitable for disposal within a GDF. For reuse in MOx fuel, NDA is investigating the possibility of production of MOx for LWR type reactors. NDA has requested that NNL investigate re-purposing the current Fuel Line for the new dual purpose of making fuel-quality LWR or disposal-grade MOx through the use of an industrially proven Masterblend process, but also retain the SBR type equipment to allow as many powder processing options to remain open for reactor or disposal-grade MOx to be developed. A single works contract for the full scope of the works will be awarded to the successful supplier, under which the supplier will be required to deliver the following elements: • Preliminary Design • Detailed Design • Procurement • Assembly/Manufacture • Offsite testing • On site installation & testing • Design and Technical Support to Commissioning and Handover; and • Training The contract will be split into 3 Sections, under the NEC3 ECC optional clause X5 (Section Completion): • Section 1 – Completion of Preliminary Design • Section 2 – Completion of Detailed Design • Section 3 – Completion of the remainder of the Works
