Significant Milestone Reached With Concrete 'mega Pour'
30th December 2020
Work on Dounreay's newest radioactive waste store went up a storey last week, with the completion of a ‘mega' concrete pour.
The construction project was one of the first to re-start work on 22 June, following the easing of lock down restrictions. The 60-strong team has had to learn COVID-19 compliant ways of working, sometimes in close proximity with each other, to keep themselves and their colleagues safe on site. Since then they have poured 1,500 tonnes of concrete and the building walls have now risen to above the first floor level.
Last week the team embarked on the biggest concrete pour of the project so far, working for 9 hours to lay the floor slab in the crane maintenance bay (CMB) on the first floor of the building, with 27 lorries delivering 425 tonnes of concrete. An overnight shift completed the job in the early hours of the morning.
Dounreay Project Manager Dave Busby said that casting the CMB floor slab was a significant construction milestone as it will allow the team to install the 170 tonne CMB shield door early next year.
The team has overcome considerable obstacles this year, being COVID-19 compliant as they continue to work through the pandemic.
Dounreay awarded the contract to construct the new intermediate level waste store to GRAHAM Construction Ltd. Work started in 2018 and is expected to take around 3 years to complete. It will hold drums of waste in safe long term storage in accordance with Scottish Government policy.
Dounreay is Scotland’s largest nuclear decommissioning project and is widely recognised as one of Europe’s most complex nuclear closure programmes. The work is being delivered by DSRL, a company owned by Cavendish Dounreay Partnership, on behalf of the Nuclear Decommissioning Authority.
Ground-breaking research published in Nature Communications shows that traces of plutonium in the environment can be identified as being from global or local sources. Using soil samples taken from Dounreay, an area near to the site and 2 areas at a distance from the site, the research showed that it was possible to identify whether minute traces of plutonium in the soil came from plutonium ‘bred' in a reactor or from global fallout.
Statement issue18 March 2021 by NDA, Dounreay and Sellafield. In 2013 we concluded the development of our strategy to remove unirradiated nuclear material from Dounreay and consolidate it at Sellafield.
Dounreay has awarded an important waste clean-up contract to Jacobs as the site plans for the future of its deepest historic radioactive waste store. Jacobs and its supporting partners have been awarded a 6-year contract to provide a design management team to produce a fully integrated design for the shaft and silo project.
14 successful companies have been awarded contracts to come up with innovative approaches to remotely sort and segregate radioactive waste. The ‘Sort and Seg' innovation competition, worth £3.9 million in total, was launched in July 2020.
David Peattie, Chief Executive Officer of the Nuclear Decommissioning Authority, has announced the appointment of Lawrie Haynes as Chair Designate of Dounreay Site Restoration Ltd. (DSRL).
Dounreay features in a new leaflet from the Nuclear Decommissioning Agency showing recent research, development and innovation. See the leaflet link at the bottom of this page to read about some of the other investments by the NDA.
UK-Japan relationship in nuclear science boosted by robotics and automation. Britain and Japan have signed a research and technology deployment collaboration to help automate nuclear decommissioning and aspects of fusion energy production.
Issued by David Peattie, Group CEO and Accounting Officer, NDA. I am pleased to be able to share with you some significant developments within the NDA around our transport and waste businesses, further underlining our One NDA approach to working more collaboratively and efficiently to clean up the UK's earliest civil nuclear sites.
The Decommissioning Services Framework (DDF) Alliance, led by Cavendish Nuclear and supported by KDC Contractors (Veolia) and BAM Nuttall (BAM), has been successfully awarded a contract for the design of a new waste repackaging facility at the Dounreay nuclear site. The programme of work is expected to run until early 2022 and forms part of Dounreay Site Restoration Limited's (DSRL's) Decommissioning Services Framework.
Dounreay Site Restoration Limited (DSRL) has announced the appointment of Mark Rouse as its Managing Director. Mark took up the position of Managing Director in March 2020 but will now move from the current parent body organisation to Dounreay Site Restoration Limited to continue leading the business when it becomes an NDA subsidiary on 1 April 2021.
