Caithness firm aid trials for Dounreay clean-up
Published 08 Oct 2014Caithness firm JGC Engineering and Technical services have been providing fabrication and operator support to the Dounreay Site Restoration Limited (DSRL) team, as they seek to develop solutions to remove radioactive waste from Dounreay’s shaft and silo.
Work is underway at JGC’s Janetstown base to develop the waste retrieval process at Dounreay. The processes being trialed re-uses redundant equipment from previous trials, with the team borrowing further equipment from across the Nuclear Decommissioning Authority (NDA) estate to keep costs to a minimum. The work involves taking the raw waste (simulated sludge and waste from the local recycling centre) and processing it through size reduction, sorting/segregation and packaging systems to produce a final waste product which is suitable for removal.
Andrew Polson, a design engineer who is leading the DSRL team, said “The trials have already proved to be worthwhile and have provided invaluable information to assist the design. Methods of waste treatment originally planned have proved to be unsuccessful and the trials work has enabled effective solutions to be developed.”
