Radioactivity Found In A Drainage System Near Dounreay
28th July 2014
The Environmental Closure & Demolition department at Dounreay have found elevated levels of radioactivity in a manhole in a redundant offsite drainage system.
Samples of sludge were taken from the manhole which indicated elevated levels of alpha activity.
DSRL have agreed with SEPA that they will obtain further samples and subject them to detailed analysis to confirm the level and source of the radioactivity. The results are expected mid-August.
Until the result of the analysis is received, DSRL does not wish to speculate on what the activity is and where it came from, although we are investigating the possibility that the activity in the manhole may have come from sludges produced at the Shebster water treatment plant upstream of the manhole.
There was a pipeline from the water works that enabled sludges from treatment at the works to be disposed into the Dounreay drainage system, which was disconnected in 2011.
DSRL is keeping SEPA informed, and will report on the findings once all the analysis has been complete.
Work is underway to retrieve the last remaining radioactive fuel elements that have been stuck for decades inside the iconic Dounreay Fast Reactor (DFR). The experimental dome-shaped nuclear reactor once led the world in fast breeder technology and after it closed in 1977 most of the core fuel was removed.
Eleven young people who have completed their Dounreay apprentice training are "very much a part of the future of the far north." Guest speaker Jamie Stone MP told the audience at the apprentice indenture ceremony that took place last Friday that, as Dounreay continues to decommission, the newly indentured apprentices would be an important part of the area's ability to offer a skilled and innovative workforce. Dounreay Managing Director and former nuclear industry apprentice Phil Craig added: “I am very proud that we are celebrating yet another group of talented apprentices.
Companies are being invited to LINC together and support Scotland's largest decommissioning project thanks to an innovative new scheme designed to increase the number of small and medium enterprises (SMEs) delivering clean-up work at Dounreay. Up to five companies will be invited to help understand and develop the best proposal for size-reducing all of the machinery and components that will need to be removed from Dounreay's Prototype Fast Reactor (PFR) - the largest to be built at the Caithness site.
Graduates from as far afield as Portugal and London arrived in Caithness last week to kick start their career at Dounreay. Ten new recruits have started on the two-year graduate scheme with educational backgrounds as diverse as engineering, law and digital forensics and ethical hacking.
It is 60 years this weekend since the first criticality was achieved in Scotland using a test rig at Dounreay. Now the decommissioning team responsible for the site is marking that milestone by taking a major step towards demolishing the oldest reactor that remains at the former fast reactor research centre.
This film, produced by AEA Technology in 1994, looks back on the history of the fast reactor development programme at Dounreay..
Progress across Dounreay's decommissioning programme is being showcased in a new film and brochure highlighting the team's successes during 2016-17. Some of the highest hazards that remained in the Nuclear Decommissioning Authority estate, including liquid metal coolant from the Dounreay Fast Reactor, were reduced and destroyed during the year bringing to a successful conclusion projects that spanned many years.
The biggest networking event in Europe for nuclear decommissioning will be held in Manchester. 2 November 2017.
A planning application will be submitted to Highland Council later this year to cover the next phase of planning at the Dounreay site. Planning permission from 2018 to the shutdown of the site, also known as the interim end state, is the third phase of the planning required for the Dounreay decommissioning programme.
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.
