A thriving nuclear industry is crucial to the UKs energy security and to clean up the legacy of over 50 years of nuclear power. The research performed in the ICO (Imperial Cambridge Open universities, pronounced ECO!) CDT will enable current reactors to be used longer, enable new reactors to be built and operated more safely, support the clean up and decommissioning of the UKs contaminated nuclear sites and place the UK at the forefront of international programmes for future reactors for civil and marine power. It will also provide a highly skilled and trained cohort of nuclear PhDs with a global vision and international outlook entirely appropriate for the UK nuclear industry, academia, regulators and government. Key areas where ICO CDT will significantly improve our current understanding include in civil, structural, mechanical and chemical engineering as well as earth science and materials science. Specifically, in metallurgy we will perform world-leading research into steels in reactor and storage applications, Zr alloy cladding, welding, creep/fatigue and surface treatments for enhanced integrity. Other materials topics to be covered include developing improved and more durable ceramic, glass, glass composite and cement wasteforms; reactor life extension and structural integrity; and corrosion of metallic waste containers during storage and disposal. In engineering we will provide step change understanding of modelling of a number of areas including in: Reactor Physics (radionuclide transport, neutron transport in reactor systems, simulating radiation-fluid-solid interactions in reactors and finite element methods for transient kinetics of severe accident scenarios); Reactor Thermal Hydraulics (assessment of critical heat flux for reactors, buoyancy-driven natural circulation coolant flows for nuclear safety, simulated dynamics and heat transfer characteristics of severe accidents in nuclear reactors); and Materials and Structural Integrity (residual stress prediction, fuel performance, combined crystal plasticity and discrete dislocation modelling of failure in Zr cladding alloys, sensor materials and wasteforms). In earth science and engineering we will extend modelling of severe accidents to enable events arising from accidents such as those at Chernobyl and Fukushima to be predicted; and examine near field (waste and in repository materials) and far field (geology of rocks surrounding the repository) issues including radionuclide sorption and transport of relevance to the UKs geological repository (especially in geomechanics and rock fracture). In addition, we will make key advances in development of next generation fission reactors such as examining flow behaviour of molten salts, new fuel materials, ultra high temperature non-oxide and MAX phase ceramics for fuels and cladding, thoria fuels and materials issues including disposal of wastes from Small Modular Reactors. We will examine areas of symbiosis in research for next generation fission and fusion reactors. A key aspect of the ICO CDT will be the global outlook given to the students and the training in dealing with the media, a key issue in a sensitive topic such as nuclear where a sensible and science-based debate is crucial.

The EPSRC Centre for Doctoral Training (CDT) in Nuclear Energy Futures aims to train a new generation of international leaders, at PhD level, in nuclear energy technology. It is made up of Imperial College London (lead), Bristol University, Cambridge University, Open University and Bangor University. These institutions are some of the UK's leading institutions for research and teaching in nuclear power. The CDTs key focus is around nuclear fission i.e. that is the method of producing energy by splitting the atom, which currently accounts for 11% of the world's electricity and 20% of the UK's electricity, whilst producing very low levels of carbon emissions (at levels the same as renewable energy, such as wind). The CDT whilst focused on fission energy technologies will also have PhD projects related to fusion nuclear energy and projects needed or related to nuclear energy such as seismic studies, robotics, data analytics, environmental studies, policy and law. The CDT's major focus is related to the New Nuclear Build activities at Hinkley Point, Somerset and the Anglesey site in north Wales, where EDF Energy and Horizon, respectively, are building new fission power plants that will produce around 3.2 and 2.7 GWe of nuclear power (about 13% of the UK current electricity demand). The CDT will provide the skills needed for research related to these plants and potential future industry leaders, for nuclear decommissioning of current plants (due to come off-line in the next decade) and to lead the UK in new and innovative technologies for nuclear waste disposal and new reactor technologies such as small modular reactors (SMRs). The need for new talented PhD level people is very high as many of the UK's current technical experts were recruited in the 1970s and 80s and many are near retirement and skills sector studies have shown many more are needed for the new build projects. The CDT will champion teaching innovation and will produce a series of bespoke courses that can be delivered via on-line media by the very best experts in the field from across the CDT covering areas such as the nuclear fuel cycle; waste and decommissioning; small modular reactors; policy, economics and regulation; thermal hydraulics and reactor physics as well as leading on responsible research and innovation in the sector. The CDT is supported by a wide range of nuclear companies and stakeholders. These include those involved in the new build process in the UK such as EDF Energy, Hitachi-GE, Horizon and Rolls-Royce, the latter of which are developing a UK advanced modular reactor design. International nuclear stakeholders from countries such as the USA, UAE, Australia and France will support the student development and the CDT programme. The students in the CDT will cover a very broad training in all aspects of nuclear power and importantly for this sector will engage in both media training activities and public outreach to make nuclear power more open to the public, government and scientists and engineers outside of the discipline.
