A fast pneumatic transfer system for an instrumental neutron activation analysis and delayed neutron counting system were
reconstructed with new designs of a functional improvement at the HANARO research reactor in 2006. The design, conception,
operation and control of these systems are described. Also the experimental characteristic parameters by a functional operation
test and an irradiation test of these systems, such as the transfer time, the neutron flux, the temperature of the irradiation
position with an irradiation time, the radiation dose rate when the rabbit is returned, etc., are reported to provide a user
information as well as for the management and safety of the reactor.
