Benchmark results of various particle fuels for small reactors without on-site refueling

The first Research Coordination Meeting of the International Atomic Energy Agency's Coordinated Research Project (CRP) on 'Small Reactors without On-site Refueling' was held from 21 to 25 November 2005, at the Agency's Headquarters in Vienna. Small Reactors without On-site Refueling (SRWORs) are defined as reactors which have a capability to operate without refueling and reshuffling of fuel for a reasonably long period consistent with the plant economics and energy security, with no fresh and spent fuel being stored at the site outside the reactor during its service life. The participants and observers were 19 in total from the involved 18 research institutions and organizations of Brazil, Croatia, India, Indonesia, Italy, Japan, Lithuania, Morocco, the Russian Federation, the United States of America and Vietnam. The purpose of the meeting was to present the results achieved, discuss progress and plan the future work related to the CRP. At the meeting, the participants were assigned into three groups to discuss respective topics in detail. One of the topics was design and technology development for LWRs with coated particle based fuel. The present paper discusses the benchmark results of various types of small reactors with particle based fuel. (author)
