First Generation Magnox Fuel Storage Pond

Sellafield Ltd

The First Generation Magnox Fuel Storage Pond was an open air pond constructed during the 1950s.

Due to a lengthy reprocessing shut down, fuel was stored under water for abnormally long periods of time, leading to excessive corrosion of the fuel, causing increased radiation levels. The waste now consists of sludge, Magnox fuel, intermediate level waste, and low level waste. Each of these waste streams needs to be removed and processed through separate routes.

RPS is supporting the retrievals and long term storage project for the waste, with a safety team working in conjunction with Sellafield Limited. We have developed innovative safety case approaches which facilitate safe and effective decommissioning, and allow ready revision as the engineering solution develops.
