Abstract: China Advanced Research Reactor (CARR) is a high-performance and multi-purposes research reactor built in the 21st century in China. It is an important scientific research and experimental utilization platform for basic research and application of neutron physics, research of reactor fuel and material irradiation performance and development of radio-isotopes production. CARR adopts an anti-neutron trap core design to provide sufficient space for horizontal neutron beam and vertical irradiation channels, which improves the comprehensive capacity of experimental research and irradiation tests to meet the needs of multi-purposes utilizations. The CARR utilization facilities, main uses, irradiation tests and experimental application capacities, as well as the enhancement program of comprehensive utilizations and future development of the scientific research platform were outlined in the paper.
