100% SUCCESS FOR BURY COMPANY IN NUCLEAR PLANT TRIALS

After extensive trials, a specialised extract and filtration system has been installed at Sellafield by Bury based heating and ventilation contractor, Senior Hargreaves.  The system will be used in the Windscale Advanced Gas Reactor (WAGR) decommissioning project to ensure complete recovery of all airborne particles during the removal of the reactor shell.

Before acceptance by their client, the plant was fully assembled at Hargreaves' Lord Street factory and challenged over two weeks continuous use.  During this time, materials similar in size and density to the cutting residues were introduced in controlled quantities.  Coarse, medium, fine and superfine residues were captured with a 100 per cent recovery rate.

Designed by engineers BNFL Environmental Services, the plant was fabricated to their exact specification by Hargreaves.  The system has four stages of separation and filtration.  All ductwork and major plant items are stainless steel to meet nuclear industry standards.  The process is adaptable to deal with welding fumes from fabrication and other activities that generate fume and dust.  It will be in use from September 2003 and is expected to run continuously for the foreseeable future.

Hargreaves association with BNFL at Sellafield dates back more than 30-years.
