The last time a human entered our Pile Fuel Storage Pond was in 1958, when records show a maintenance operator and health physics monitor carried out a dive into the newly constructed pond to repair a broken winch. At least that was true until December 2022 when Josh Everett, a diver from the specialist U.S nuclear diving team Underwater Construction Corporation Ltd, became the first person in over 60 years to carry out work in the pond. Sending human divers into a contaminated pond may seem to run counter to modern nuclear clean-up and decommissioning techniques that commonly use robots and other tools for this type of work, but these are no ordinary divers. Josh and his team have years of experience in safely diving in radioactive environments around the world, including at Dungeness A and Sizewell A in the UK but the Pile Fuel Storage Pond project is a first for us at Sellafield. Carl Carruthers, our head of programme delivery for legacy ponds, said: "The Pile Fuel Storage Pond diver project has been 5 years in the planning and has been a huge success. The team are used to diving in toxic and hazardous environments all over the world, including inside nuclear reactor vessels, but this is a first for us." "Safety has been our priority throughout, and the divers are monitored and communicating with the dive supervisor at all times. "Their work has helped us make real progress in cleaning up the pond and our site mission to deal with the nuclear legacy and create a clean and safe environment for future generations."

Looks like the scaffolders were also erecting in a hugely contaminated environment, kudos to them guys also 💪
Working in partnership with the team at Sellafield Ltd, UCC and our UK subsidiary were honored to deliver our nuclear diving expertise to such a critical decommissioning program. Thank you to everyone at Sellafield for ensuring this effort was safe, informative and successful.
After completing the dive, the dive master confirmed he still hadn't located his P4 pass he applied for in 1984...
We used nuclear divers in the spent fuel storage pools for the West Valley Demonstration Project more than 20 years ago. They were excellent.
Glad to have played a small part in reaching this milestone. Well done to all involved and safe diving!
It's surprising that the maintenance requirements weren't anticipated during the design phase. Perhaps more thorough planning and consideration could have prevented this oversight.
Wow. Difficult to appreciate this level of risk management. Pre and post activity being completed.
A lot of planning must have gone into this. Well done to all involved.

1ySome achievement Sellafield Ltd and I note it was reported by Office for Nuclear Regulation also today. Will there be an opportunity to learn from your experience here and share the work that went into achieving this? Safety analysis, risk management and your satisfaction of the ALARP principle would be great to see when you are ready to share. Hazards Forum Nick Shaw, Ryan Maitland
