Stabilisation, Excavation and Segregation
1 Aug 2017 to 31 Oct 2017
Dismantling process equipment and supporting steel in nuclear cells is made complex by the requirement to carry out multiple steps in a hazardous environment where working times are limited. Eliminating as many of these steps from the dismantling process as is practical has the effect of accelerating dismantling, leading to improvements in productivity an...
Smart Map - Interactive Virtual Engineering
1 Feb 2017 to 31 Aug 2017
Autonomous drones are revolutionising the way we perform surveys, allowing us to accurately recreate nuclear sites digitally. Being able to examine nuclear sites digitally enables better, more informed decision making, safer operational practises and more effective planning and communications. Smart Map is a cloud based 3D map that unlocks the potential o...
D:EEP : Estimating Entrained Products
1 Apr 2015 to 30 Jun 2018
Dealing with nuclear legacy is expensive. A universal challenge found at many nuclear facilities is that associated with the management of entrained radioactivity within the walls of nuclear waste storage facilities found on many nuclear sites. Correct classification of the waste can significantly improve the planning process for decommissioning and the r...
Thermal Treatment of Irradiated Graphite
1 Apr 2015 to 30 Sep 2017
A key challenge in the decommissioning of UK and international nuclear facilities is the management of irradiated graphite. Graphite is used as a neutron moderator, reflector, etc in most of the UK’s reactors , and is a very bulky material which is difficult to remove intact from the reactor core at the end of life. If it is removed from the core it repre...
Treatment of Irradiated Graphite – ‘From Core to Capture’
1 Jun 2013 to 30 Apr 2016
Irradiated graphite is one of the key challenges in decommissioning and radioactive waste management of UK and international legacy nuclear facilities. Graphite is a very bulky form of radioactive waste which is difficult to remove from the reactor core at the end of life. If it is removed from the core it represents a large, and hence expensive, waste st...
Plasma Vitrification of Intermediate Level Waste
1 May 2013 to 30 Apr 2015
Costain Energy and Process and Tetronics are working together to develop a treatment method for Intermediate Level Waste using a DC Plasma system. Although DC plasma treatment is established for hazardous waste treatment it is not yet in commercial use for ILW. It is proposed to design, build and demonstrate operation of a ‘nuclear aligned’ DC plasma vitr...
