Workshop on Advanced Reactors With Innovative Fuels
A new generation of reactor designs are being developed that are intended to meet the requirements of the 21st Century. In the short term, the most important requirement is to overcome the relative non-competitiveness of current reactor designs in the deregulated market. For this purpose, evolutionary light water reactor (LWR) designs have been maturing and are being promoted actively. These are specifically designed to be less expensive to build and operate than the previous generation of LWRs, genuinely competitive with alternative forms of generation and at the same time establish higher levels of safety. A new generation of modular, small-to-medium (100-300 MWe/module), integral design water cooled reactors are under development. These are designed to be competitive with nuclear and non-nuclear power plants, to have significantly enhanced safety, to be proliferation resistant and to reduce the amount of radioactive waste produced. A different approach to improve competitiveness is the re-emergence of high temperature reactors (HTR) using gas turbine technology to give higher thermal efficiencies, low construction and operating costs, inherent safety characteristics, and low proliferation risk.
In the longer term other requirements related to long term sustainability will emerge. These requirements have been outlined in the U.S. DOE Office of Nuclear Energy, Science and Technology’s Generation IV nuclear energy systems that offer advantages in the areas of economics, safety and reliability, sustainability, and that are commercially deployable by 2030. The Generation IV International Forum (GIF) has been formed to advance these goals on an international level combining the research and development resources of the participating countries. The need to establish sustainability of the fuel cycle to minimize waste has also led to the development of the Advanced Fuel Cycle Initiative in the United States and continued research in Europe under the 6th Framework Program. Under these and other programs, the sustainability of the nuclear option is being developed to ensure that it is a viable option for the long term.
Therefore, in this context, the following topics are of interest are:
Particular goals of the workshop were to identify research and development needs and the roles which can be played by existing experimental facilities as well as possible needs for new experimental facilities. The conclusions of the technical sessions were synthesised and discussed by a round table on international co-operation to facilitate the introduction of new reactor systems.Related links
