Sellafield - 70 tonnes of sludge

Seventy tonnes of radioactive waste have been removed from a nuclear

site’s most hazardous building. Teams at Sellafield in Cumbria have removed
the waste from the Magnox Swarf Storage Silos with the company saying it
has placed it into safe storage. The work began in 2022 after two decades
of preparation, because when the building was constructed in the 1960s
no-one had considered how the waste would be removed. Sellafield’s head of
legacy silos Phil Reeve said so much waste had been removed that a 7m
(23ft) crater had been dug in the middle of the pile. However, the crater
presents a risk of the waste around the edges collapsing inwards. To fix
the issue, Sellafield has created its own version of a garden rake – a 1.4
tonne machine which uses its stainless steel arms to pull the nuclear waste
into the centre.
