Abstract
Currently, the 15-MW Heavy Water Research Reactor (HWRR) at the China Institute of Atomic Energy (CIAE) in Beijing is the only neutron source available for neutron-scattering experiments in China. A 60-MW tank-in-pool inverse neutron trap-type research reactor, the China Advanced Research Reactor (CARR), is now being built at CIAE to meet the increasing demand of neutron-scattering research in China. According to the design, the maximum unperturbed thermal neutron flux is expected to be 8×1014 n/cm2 s in the reflector region. Seven out of nine tangential horizontal beam tubes will be dedicated for neutron-scattering experiments. A cold source, a hot source and a 30×60 m2 guide-tube hall will also be constructed. In this paper, a brief introduction to HWRR, the existing neutron-scattering facilities and research activities at HWRR, CARR and the facilities to be built at CARR are presented.
