The AVR as Small Modular Thorium Very High Temperature Reactor:Experiences-Design-Safety-Fuel Cycle

摘要

As a young engineer in the power plant department of Brown Boveri,Dr.Schulten had the idea to design nuclear power stations without major risk.The following requirements must be accomplished:ŸA negative temperature coefficient had to avoid an MCA(Maximum Credible Accident);ŸCeramic materials for core construction and fuel elements;ŸA homogenous mixture of nuclear fuel and graphite had to be able to use uranium and thorium as breeding material;ŸThe produced high temperature heat shall be the basis for production of electricity,drinking water,hydrogen,etc.;ŸA relatively simple plant,which could be operated in developing countries,to cogenerate electricity and heat;ŸHelium used as cooling gas.
