The High-Flux Advanced Neutron Application Reactor (HANARO ; Korean : 하나로) is a 30 MW multi-purpose research reactor located at Daejeon, Republic of Korea. It was designed by Korea Atomic Energy Research Institute (KAERI) as a facility for research and development on the neutron science and its applications. HANARO has been playing a significant role as a national facility in the area of neutron science, the production of key radioisotopes, material testing for power reactor application, neutron transmutation doping (NTD), neutron activation analysis, and neutron radiography. After the installation of a cold neutron source in 2010, it has been also serving as a regional and international facility for neutron science.
