Project SAV

Project Details

Value: £16m

Location: Sellafield

Client: Sellafield Ltd

Completion Date: Apr 2013

Sellafield is a large multi-function nuclear site close to Seascale on the coast of Cumbria, England where for over 30 years Exyte Hargreaves has been involved in ventilation works there.

Exyte Hargreaves, were appointed the major contract for project SAV at the Sellafield nuclear reprocessing site in Cumbria. The Separation Area Ventilation (SAV) project involved the replacement of legacy ventilation systems, the re-routing of exhaust ductwork and the creation of new filters and a discharge stack.

The project permitted the decommissioning of the stack associated with the primary separation and head end facility, a major landmark on the site dating from the 1940’s. Before this was done, a new stack with a large filter and fan house was built and ventilation was re-routed around the site.

This involved the fabrication of a network of 3000 metres of ductwork and its installation onto existing and new high level pipe bridges. The six ducts feeding the stack comprised up to 2500 individual pieces of bespoke ductwork. The flues within the stacks where also be made by Exyte Hargreaves as was the filter banks and fan housings.

To minimise long-term maintenance, all of the ductwork was fabricated in stainless steel, requiring approximately 500 tonnes of material.
