CHINA ADVANCED RESEARCH REACTOR (CARR) - A NEW REACTOR TO BE BUILT INCHINA FOR NEUTRON-SCATTERING STUDIES

This paper outlines the main features of the CARR, a 60 MW tank-in-poo l inverse neutron trap-type research reactor, which will soon be built at China Institute of Atomic Energy in Beijing to meet the increasing demands of neutron scattering research as well as isotope production in China. According to the design, slightly pressurized light water wi ll be used both as the moderator and the primary cooling water. The un dermoderated core will be surrounded by heavy water reflector, where t he maximum unperturbed thermal neutron flux would be expected to be 8 x 10(14) n/s cm(2) at 60 MW. Nine tangent horizontal beam tubes and so me vertical tubes will be installed in the reflector. A cold source, a hot source and a 30 x 50 m(2) guide tube hall will be equipped. The C ARR is due to come critical in the year of 2004. (C) 1998 Elsevier Sci ence B.V. All rights reserved.
