More Than 30,000 Bricks Removed From Redundant Plant
30th November 2016
More than 30,000 bricks have been removed from three pits within a redundant facility as part of a project to decommission a former effluent treatment plant.
A scaffold platform has been constructed to allow operators, wearing full airline suits, access to remove the bricks using small electrically operated hand tools. The bricks are then transported to ground level in containers using a conveyor belt.
The bricks are then monitored by health physics to confirm their classification as low level waste before being packaged in steel waste crates for disposal and long term storage.
Around 85,000 bricks are expected to be removed by the time the project is completed.
Ross Mackay, Project Supervisor, said: "This project so far has been very interesting and also challenging at times. The team has shown excellent innovation throughout and brought skills and techniques from previous projects they worked on to make this job flow as smoothly and as safely as possible. Our aim is to continue with a positive attitude and complete this task safely. "
The clean-up of the nuclear estate is a key priority for both the Scottish and United Kingdom governments. Dounreay's decommissioning is well established with the site due to reach an interim end state by the early 2030s.
A major upgrade and expansion of Dounreay's Thurso town centre office has been completed. David Flear, Chair of Dounreay Stakeholder Group, officially reopened the building which sits at the entrance to the high street and has been the site's public information office for almost a decade.
The first block of concrete has been removed from the structure of one of Dounreay's cooling ponds - representing a major first step in demolishing the redundant giant chamber. The pond is one of two concrete pits, six metres deep, which was used to store spent fuel from the Dounreay Fast Reactor (DFR).
Amec Foster Wheeluker has been awarded a contract to design and build a new effluent treatment plant at Dounreay. The agreement signals a landmark move for the Caithness site as the first to incorporate socio-economic commitments following the introduction of a new procurement policy earlier this year.
His Excellency, Mr Koji Tsuruoka, Ambassador of Japan to the United Kingdom, Mr Yosuki Ishigami from the Economic Section of the Japanese Embassy and Mr Daisuke Matsunaga, Consul General of Japan in Edinburgh visited Dounreay during a two-day visit to the north of Scotland as a guest of Dr Paul Monaghan MP. At Dounreay the group toured the Prototype Fast Reactor (PFR), including the reactor hall.
Dounreay has said "you're hired" to ten local newcomers who have started their careers at Dounreay this week. This makes it the 61st consecutive year that apprentices have joined the site.
An off the shelf CCTV camera is providing crystal clear images from the depths of Dounreay's Prototype Fast Reactor (PFR). Fifty years on from the construction of PFR, the reactor decommissioning team is viewing footage that will enable it to pull apart the innards of the second and last fast reactor to be built in the UK.
The last of the higher activity liquid waste produced during Dounreay Fast Reactor (DFR) fuel reprocessing has been made safe for future generations. It is an important milestone in the immobilisation of the historic liquid waste, known as raffinate, created from reprocessing undertaken during the operation of Dounreay's three reactors.
Ten new graduates started their careers at Dounreay this week as the company's graduate development programme entered its second year. Applications to the scheme soared after the success of last year's first ever graduate intake, with more than 200 applications received.
The destruction of one of the highest hazards remaining in the Nuclear Decommissioning Authority (NDA) estate has been completed at Dounreay. Around 68 tonnes of highly radioactive liquid metal coolant was removed from the Dounreay Fast Reactor (DFR) and safely destroyed over a ten year period.
