Winfrith SGHWR Decommissioning
Winfrith, Dorset, UK · Operations 1967-1990, Decommissioning ongoing (started 1990s) · Part of NRS decommissioning budget
The judgement call
Account-gated at launchWinfrith was a center for nuclear research and development, and its decommissioning involves unique challenges associated with experimental reactor types. - Significant progress has been made in decommissioning facilities and transferring waste, demonstrating effective hazard reduction. - The site is being re-used, highlighting the potential for repurposing former nuclear sites after decommissioning.
Key engineering challenges
Decommissioning a unique Steam Generating Heavy Water Reactor (SGHWR) prototype. - Managing the removal of any remaining heavy water and associated radioactive materials. - Dismantling complex reactor buildings and facilities, including the Dragon reactor. - Transferring and storing various types of radioactive waste generated during decommissioning.
