Abstract
At present, the 15 MW Heavy Water Research Reactor (HWRR) at China Institute of Atomic Energy (CIAE) in Beijing is the only neutron source available for neutron-scattering research in China. A 60 MW tank-in-pool inverse neutron trap-type research reactor, China Advanced Research Reactor (CARR), now is being built at CIAE in Beijing to meet the increasing demand of neutron-scattering research in China. The maximum unperturbed thermal neutron flux would be expected to be 8×10 14 n cm −2 s −1 in the reflector. Seven tangent horizontal beam tubes will be used for neutron scattering experiments. A cold source and a 30×60 m 2 guide hall will be constructed. In this paper, a brief introduction of HWRR, the existing neutron-scattering facilities and research activities at HWRR, and the facilities to be built at CARR are presented.
