    China Mianyang Research Reactor (CMRR) is a multi-purpose and high-flux research reactor, which is built at Mianyang city of Sichuan province. Focusing on the efficient application of reactor neutron resources, three scientific platforms are gradually built on CMRR, which can carry out material irradiation effect research, radioactive isotope production, neutron science research, etc. CMRR reactor adopts the design of normal temperature, normal pressure and deep-pool submergence to ensure the absolute safety of reactor in various accidents. The anti-neutron trap reactor core is designed to form the peak fast neutron flux rate of 3.4×1014 n?cm-2?s-1 in reactor active region, and the peak thermal neutron flux rate of 2.0×1014 n?cm-2?s-1 in the heavy water tank with sufficient experimental space provided for material irradiation and neutron scientific research. In this paper, the basic parameters, structure design, layout of CMRR and main research progress of CMRR reactor in material irradiation effect study, radioactive isotope production, neutron science research are comprehensively and systematically summarized.
