Nuclear Decommissioning Authority
In 1946, just as Britain was recovering from the end of the World War 2, pioneering scientists at Harwell introduced the UK to civil nuclear power including development of western Europes first nuclear reactor.
Based on a former RAF airfield, Harwell was initially taken over by the Ministry of Supply to become the Atomic Energy Research Establishment. This then became the UKs centre for research into civil nuclear power with a wide range of experimental facilities.
In total, 14 experimental reactors were built on the site, including the UKs first fast reactor.
So important was Harwell to the UK that, during the past 70 years, the great and the good flocked to see the work first-hand, including Sir Winston Churchill, Margaret Thatcher, and Her Majesty The Queen and HRH the Duke of Edinburgh.
By the late 1980s, the requirements for nuclear research and development had reduced significantly, with Harwells last 3 reactors closing in 1990. The site, moved into non-nuclear and commercial research, and then to reactor decommissioning, waste management and site restoration.
Over the years, substantial progress has been made on the decommissioning and environmental restoration programme. A quarter of the 102-hectare site has already been de-licensed and released for other uses. The reduction of the sites boundaries has allowed for significant development on the neighbouring campus, as it continues to grow into a major centre for science and innovation.
Today, Harwell is focused on decommissioning its remaining 3 nuclear reactors.
Gary Reid, Harwell Integration Manager, said:
It is amazing to see the significant changes over the decades. What hasnt changed is the unrelenting focus on world-class science and innovation; the focus is now on the safe decommissioning of the site and restoration of the land.
NDAs Chief Financial Officer, David Batters, said:
We welcome the significant progress in safely decommissioning the Harwell site, with over 100 buildings and facilities now demolished. We are working closely with Magnox Ltd on ensuring their plans present value for money and achieve site clearance as soon as possible.
