£2million Plan For Closure At Landfill Site
15th January 2011
Dounreay Site Restoration Ltd wants to restore an area of land designated as a rubble dump during the construction and operation phases of the site.
An estimated 70,000m3 of material from the construction and demolition of buildings was deposited in the area beyond the eastern perimeter of the site from 1960 or so.
The site, known as Landfill 42, was taken out of use in 2005 and needs to be restored under environmental and planning regulations.
This will involve repositioning approximately 16,000m3 of material and the construction of a new sea defence. A substantial impermeable membrane and an estimated 25,000 tonnes of rock will be used in the closure works.
The work is expected to cost £1-2 million and, subject to regulatory controls, is due for completion by the end of 2011.
Gas and groundwater monitoring will continue for a number of years after restoration until the licence can be surrendered to the Scottish Environment Protection Agency.
The landfill is known to contain hazardous materials, including metals, asbestos and minor radioactive pollution from ground excavation and building demolition work dating back to the 1960s and 1970s.
Phil Cartwright, contaminated land manager at DSRL, said extensive work had been carried out in recent years to characterise the facility.
"We studied several options for closure of the landfill and carefully considered the environmental impact of each," he said.
"We believe the facility can be left in a safe condition with the engineering measures identified in our closure application to the Scottish Environment Protection Agency."
The landfill is adjacent to ground now being developed as a site for the disposal of low-level radioactive waste from decommissioning the site.£2million Closure Plan For Landfill site
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.
A unique new archive, funded by the Nuclear Decommissioning Authority, has opened its doors to the public for the first time, bringing together historical nuclear records from all over the UK. Speaking today at the Nucleus (Nuclear and Caithness Archive) in Wick, NDA chairman Stephen Henwood, said:Today we see a new chapter in the important role Caithness has played in the UK's nuclear history.
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).
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.
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.
