CHARACTERISTICS OF A NEW PNEUMATIC TRANSFER SYSTEM FOR A NEUTRON ACTIVATION ANALYSIS AT THE HANARO RESEARCH REACTOR

다국어 초록 (Multilingual Abstract)

A rapid pneumatic transfer system (PTS) for an instrumental neutron activation analysis (INAA) is developed as an
automatic irradiation facility involving the measurement of a short half-life nuclide and a delayed neutron counting system.
Three new PTS designs with improved functions were constructed at the HANARO research reactor in 2006. The new system is
composed of a manual system and an automatic system for both an INAA and a delayed neutron activation analysis (DNAA).
The design and basic conception of a modified PTS are described, and the functions of system operation and control, radiation
protection and emissions of radioactive gas are improved. In addition, a form of capsule transportation of these systems is
tested. The experimental results pertaining to the irradiation characteristics with variation of the neutron flux and the
temperature of the irradiation position with the irradiation time are presented, as is an analysis of the reference material for
analytical quality control and uncertainty assessments.
