2. Why bespoke engineering solutions?
Wastes – 1 April 2010 and estimated for future arising volume and masses

3. Nuclear Waste in the UK
Majority of the Nuclear wastes in the UK are stored at Sellafield in four main storage facilities.
These facilities contain waste such as: irradiated and non-irradiated steel, activated stainless steel,
reactive metals, organic / cellulosic material, graphite, cans and drums etc.

4. Why we need Bespoke Solutions
•We need unique bespoke
solutions to retrieve, size reduce
and encapsulate waste
• Two mechanical rotating, extending arms with
and end effector which is able to pick-up a rope
and crab in-cell from a crane or other device and
manage the deployment of the crab to cover the
full silo surface.
• The arms are extendable to 4 metre length and
designed and manufactured with tolerances at
full extension +/- 50mm and +/- 0.1 degree on
rotation.
• To drive the arms a chain driven system was
developed.
• SSD could be fully software integrated with the
crane or other rope and crab deployment.
•NES Solution - Second Stage
Deployment (SSD) system

5. NES Solution - Waste levelling Silo Rake
• The rake ensures waste is levelled for flat
retrieval to avoid loading the civil structure
of the silo with forces derived from the
collapsing of unlevelled waste.
• Silo rake fits inside a standard 3m3 skid for
input and export into and from the silo.
• Deployed attached by rope.
• Fully extended up to 6m length.
• Chain driven system, not hydraulic
cylinders.
• Collapses vertically in failure mode
allowing the rake to exit from the silo
• Raking does not apply forces to the civil
structure
