Sellafield바카라 사이트檚 바카라 사이트檒ocked vault바카라 사이트� gives up its nuclear secrets
One of the most challenging puzzles in the UK바카라 사이트檚 nuclear clean-up programme is being solved.
Operators in the control room of Sellafield's Pile Fuel Cladding Silo
Waste is now being routinely retrieved from one of the world바카라 사이트檚 oldest nuclear waste stores for the first time in its history.
Sellafield바카라 사이트檚 Pile Fuel Cladding Silo has effectively been a locked vault since the 1970s. That was when waste stopped being tipped into its 6 compartments.
After decades of work to figure out how to take waste from a building designed never to be emptied, retrievals teams are now doing exactly that.
So far, enough waste to fill 18 storage boxes has been cleared.
And some of the items recovered are not what you바카라 사이트檇 expect in an intermediate level nuclear waste store.
Among them is a 1960s Electrolux vacuum cleaner.
It바카라 사이트檚 believed the household hoover was used to suck up dust in the facility during its operational life in the 1950s and 60s.
Because the dust was radioactive, when the vacuum was no longer needed, the only place to dispose of it was in the silo itself.

Roddy Miller, Sellafield Ltd바카라 사이트檚 chief operating officer, said:
It바카라 사이트檚 a fantastic achievement to get to the point where we바카라 사이트檙e routinely retrieving waste from the building.
The scale of the challenge was immense. Remember, this was a facility that was not designed to be emptied.
The vacuum cleaner is a great example of how challenging it is to clear this silo. We don바카라 사이트檛 know for sure what바카라 사이트檚 in there. They didn바카라 사이트檛 keep accurate records in those days.
Anything taken into the building by the workforce of the day was likely to be contaminated because of the environment they were working in.
There was no alternative disposal route for contaminated material, so everything just went into the silo.
Ironically, a modern-day vacuum cleaner is also playing a part in the waste removal job, sucking up dust created when waste is dropped into storage boxes. It will eventually be consigned as waste itself, joining its 1960s predecessor.
Removing waste from old buildings like the Pile Fuel Cladding Silo is Sellafield바카라 사이트檚 most important job today.
Alongside it, there바카라 사이트檚 another silo and 2 ponds that need to be emptied. The ponds store used nuclear fuel underwater and were also not designed to be emptied.
Each one of these buildings needs its own unique decommissioning plan. All of them will take decades to complete.

Roddy added:
For the first time in our history, we바카라 사이트檙e routinely retrieving waste from all 4 of our legacy ponds and silos.
That바카라 사이트檚 an incredibly important milestone in our journey to clean up the site.
But there바카라 사이트檚 a lot of work yet to do and these four facilities will continue to challenge for many years to come.
Our focus now is to safely accelerate the pace of retrievals and ultimately eliminate the risk these historic buildings pose.
