The UK Government has identified plutonium immobilisation - converting plutonium-bearing material into stable waste forms such as pellets - as the preferred long-term approach for managing the UK’s civil plutonium inventory. To support this, the NDA and Sellafield Ltd is planning a future plutonium processing plant, expected to be required from the mid-2030s.

Sellafield Ltd is seeking innovative approaches to support automated inline or in-situ analysis and data management within a future plutonium processing plant. The aim is to carry out safety, quality and compliance checks directly within, or immediately alongside, key production stages for plutonium-bearing powders, pellets, cans and storage packages, enabling more frequent analysis, less manual intervention, stronger traceability and integrated digital quality assurance records.

Full details of this challenge are available on the Game Changers website. An interactive webinar will take place at 11am (GMT+1) on Tuesday 20th October 2026 where delegates will have the chance to hear directly from the challenge owners and ask any questions. Register for free via the link here.
