Robots Will Take Dounreay's Dome Apart
20th November 2011
Like something out of the Tom Cruise movie War of the Worlds, the Kuka robot has a very important job to do.
The standard industrial robot, built exactly the same as a typical car assembly line robot, will play an integral part in the demolition process of Dounreay's iconic fast reactor.
Removal of the highly hazardous and radioactive breeder slugs is the next crucial step in decommissioning the fifty year old facility.
The robot does the job traditionally undertaken by operators using manipulators whilst working through heavily shielded lead glass windows. The working area is very high in radiation - too high for people to access, so the robot does the job safely and much quicker, lowering the radiological hazards, plus providing consistency and reliability in a highly controlled environment.
The giant orange robot, built by Kuka Robotics UK Ltd, manoeuvres on a static turntable and is pre-programmed to remove the lid of the 500 litre waste drums, swab around the surface checking for traces of radioactive contamination and clean the top of the Magnox flask which stores the drums.
It operates like a giant portable pincer arm and is controlled remotely to maintain a safe, clean and secure process within the breeder packaging plant.
Inactive commissioning will be complete by the end of the financial year ready for the breeder removal operation to begin in summer 2012.
The Nuclear Decommissioning Authority (NDA), in association with the Site Licence Companies (SLCs), invite you to ‘connect and innovate' at their fifth annual event. Entry is free of charge to delegates and exhibitors.
The PFR stone table with the inscription 'Out of Caithness to the World' will become the centre piece of the NDA Archive when it opens its doors in 2017. Construction of the new facility has begun at Wick and was officially opened by David Flear, Dounreay Stakeholder Group chairman, when he cut the first turf at an opening ceremony in August.
A ceremonial turf cutting ceremony marked the official start of building work on the new archive that will store nuclear records from across the UK. David Flear, chairman of the Dounreay Stakeholder Group, dug into the ground at the Wick site where the Nuclear Decommissioning Authority's Nuclear Archive will start to take shape over the next 12 months.
UKAEA has been selected to supply the Hot Cell Remote Handling Facility for the new €1.8 billion European Spallation Source (ESS). ESS is currently under construction in Sweden.
DSRL have announced the new managing director designate, Phil Craig. With more than 20 years' experience in the nuclear industry, Phil’s career has focused on supporting the UK nuclear decommissioning, defence and existing power generation sectors.
Twelve students successfully completed the Ready Steady Work course held in early July. The four day course sponsored by DSRL and North Highland College was offered to all senior secondary schools in Wick, Thurso and Farr.
The contract applies to twelve sites throughout the UK managed by the decommissioning company Magnox Ltd as well as the nuclear site at Dounreay in Caithness, Scotland, Radioactive Waste Management Limited's site in Harwell and the Low-Level Waste Repository in West Cumbria. A number of segments make up the contrac.
A major programme milestone has been achieved with the placement of the first low level waste disposed into the new Low Level Waste Facilities at Dounreay. DSRL were granted planning permission to construct up to six vaults in April 2009.
The removal of trapped fuel elements from the Dounreay Fast Reactor moved a step closer with the successful trial of bespoke equipment to lift off the top plate. Decommissioning the 50-year-old experimental reactor is one of the most technically challenging projects in the NDA estate.
The Nuclear Decommissioning Authority, the public body that owns Dounreay and funds its clean up, has published its annual business plan, setting out key tasks for the site licence company DSRL to deliver in the next 12 months. These include: - Decontamination of Prototype Fast Reactor pond to meet regulatory requirements - Completion of construction of new fuel characterisation facilities - Material Test Reactor raffinate immobilisation complete - Continuous improvement in health, safety and environmental performance.
