Since the commencement of the HANARO operation in 1995, some reactor systems have been gradually improved for a stable operation of the reactor. The experimental facilities for a neutron activation analysis (NAA) have been developed and installed to achieve the best measurement capability. That is, the automatic and manual modes of a pneumatic transfer system (PTS) were installed at three irradiation holes and tested to setup the optimum irradiation condition. In addition, gamma-ray measurement systems have been used for the analyses of samples by a quality control system. As a result, they have been effectively used during the past ten years. A device for a prompt gamma neutron activation analysis (PGAA) became available from 2002 for boron analysis in Boron Neutron Capture Therapy (BNCT) and other light elements in solid materials. Recently, a &o-standardization method was applied for more quantitative analysis. The examples of applications and international laboratory accreditation (KOLAS-ILAC) of NAA are also described. In addition, a delayed neutron activation analysis (DNAA) system will be installed by the end of this year.
