Scotland's Oldest Nuclear Reactor At Dounreay To Go As Demolition Contract Awarded
15th December 2018
The decommissioning of Dounreay's oldest nuclear reactor has taken a major step forward with the award of a multi-million pound contract.
Dounreay Materials Test Reactor (DMTR) was the first operational nuclear reactor in Scotland and achieved criticality in 1958. It was built to test the effects of radiation on different materials and operated for 11 years.
The demolition of the reactor building will be a major skyline change for Dounreay and will signify another major hazard reduction milestone at one of the Nuclear Decommissioning Authority's (NDA) sites.
The NDA’s Director of Nuclear Operations, Alan Cumming, said:
Dounreay site, and the surrounding communities, have made an incredible contribution to the advancement of the UK’s nuclear industry for several decades. That contribution continues to this day with the pioneering work being carried out at Scotland’s largest nuclear decommissioning project.
The start of the work to demolish Dounreay Materials Test Reactor represents a significant step in our mission to decommission and clean-up the legacy from the very earliest days of the UK’s nuclear industry.
The 3-year contract has now been awarded to Cavendish Nuclear and its partners, local firm JGC Engineering, KDC and Frazer-Nash Consultancy, for the dismantling of the reactor block and demolition of the structure.
This is the culmination of a decade-long project to remove the internal structures from the reactor and its support buildings including a fuel storage pond, waste drum store and post-irradiation examination cells.
Dounreay project manager, Bill Lambie, said:When DMTR was constructed in the late 1950s, it was technologically advanced and innovative. Sixty years on, its demolition will be an important demonstration of the decommissioning progress being made at Dounreay.
We were very encouraged by the response from the supply chain and our team has worked hard to undertake a robust assessment of each of the competing bids before awarding the contract.
Cavendish Nuclear director, Natalie Nisbet, said:I am delighted our innovative and collaborative approach to reactor dismantling, using proven and cost-effective technology in conjunction with the local supply chain, will deliver the greatest skyline change seen at Dounreay for many years.
Cavendish Nuclear and its partners have pledged to source materials and services from local sub-contractors as part of its commitment to the socio-economic development of Dounreay’s supply chain and wider Caithness community.
This is the latest in a number of major contracts to be awarded in the last year as the site’s closure programme progresses.
Graham Construction was awarded a three-year contract in October and will soon begin to build an intermediate level waste storage facility on the site.
Meanwhile, Nuvia also recently announced that it had won a multi-million pound contract to remove residual liquid metal coolant from Dounreay Fast Reactor.
Dounreay, which was once the UK’s centre for fast reactor research, is now Scotland’s largest decommissioning project. The work is being delivered by Dounreay Site Restoration Limited on behalf of the NDA.
The Nuclear Decommissioning Authority and US Department of Energy's National Nuclear Security Administration (NNSA) have completed the transfer of around 700kg of highly enriched uranium (HEU) from Dounreay, in the north of Scotland, to the US. The HEU transfer, from Dounreay to the United States, was announced by the UK Government as part of its commitment to the 2016 Nuclear Security Summit held in Washington DC.
Dounreay Site Restoration Limited (DSRL) has opened the door to dozens of companies to play an active role in supporting the delivery of Scotland's largest decommissioning project. Construction of a size reduction facility, shaft and silo decommissioning and demolition of historic active laboratories are just some of the major projects expected to be delivered as part of a decommissioning services framework, potentially worth up to £400 million, which was announced on Tuesday 23rd April 2019.
The fund is provided by the Nuclear Decommissioning Authority and administered by Dounreay in association with the Dounreay Stakeholder Group. Community organisations or charities that benefit people in Caithness and North Sutherland may be eligible for assistance from the Dounreay Communities Fund.
The first blocks of concrete have been removed from the top of one of the world's most recognisable chimneys. This marks the start of the demolition of Sellafield's Windscale Pile One stack.
The latest updates on radioactive particles released from Dounreay on beaches have been published. The latest find dates were - Dounreay Foreshore 11 January 2019 Sanside Beach 11 February 2019 Murkle Beach 26 November 2016 Nuclear fuel was reprocessed at Dounreay for almost 40 years.
Employees from across the Nuclear Decommissioning Authority (NDA) group were honoured at a national awards ceremony for their work in addressing gender imbalance and diversity in the nuclear industry. Phil Craig, former Managing Director of Dounreay, scooped the coveted ‘Ally of the Year' title at the Women in Nuclear (WiN) UK conference yesterday, for being a leading male advocate of gender balance and diversity.
