ABB, the global power and automation technologies group, has supplied three industrial robots to the Paint Shop at the Land Rover manufacturing facility in Solihull, West Midlands
The system will be used in the Windscale Advanced Gas Reactor (WAGR) decommissioning project to ensure complete recovery of all airborne particles during the oxy-propane cutting of the remaining reactor shell.
Before acceptance by BNFL, the plant was fully assembled at the Hargreaves Bury factory and used continuously for two weeks.
Over this time, materials similar in size and density to the cutting residues were introduced in controlled quantities.
Coarse, medium, fine and superfine residues, down to particle sizes of 0.12 micron (less than 1/200,000 of an inch), were captured with a 100 per cent recovery rate.
Designed by engineers from BNFL Environmental Services, the plant was fabricated by Hargreaves to their exact specification.
The system has four stages of separation and filtration.
All ductwork and major plant items are stainless steel to meet nuclear industry standards.
Fabrication in mild steel and other materials is possible for other industries and the process is adaptable to deal with welding fumes from fabrication and other engineering activities.
The system includes a duplicate parallel set of separation, filtration and fan units so that extraction continues even when plant modules are serviced.
Design detailing, building and acceptance trials have gone to plan and budget.
It will be in use from September 2003 and is expected to run continuously for the foreseeable future.
Hargreaves has a long association with BNFL at Sellafield having installed high integrity ductwork and other ventilation equipment over a 30-year period.
