ABSTRACT: HANARO (High-Flux Advanced Neutron
Application Reactor) is a 30MWth multi-purpose research reactor generating a
very high neutron flux for scientific and technical applications. Since its initial
criticality in Feb. 1995, it has worked as a national neutron source for
neutron beam research, RI production and related research, material and fuel
irradiation research, and neutron transmutation doping. The installation of a
cold neutron source and related beam instrument makes HANARO serve as a
regional source for beam research as well. As Korea is developing nuclear power
systems and fuels, irradiation research is a main utilization subject in
HANARO, and irradiation facilities have been actively utilized for various
nuclear fuel and material irradiation tests requested by users from research
institutes, universities, and industries. Most of the irradiation tests were
related to the R & D relevant to the ageing management and safety
evaluation of the present nuclear power reactors. Korea is conducting R & D
programs relevant to new nuclear systems including a research reactor, System-integrated
Modular Advanced Reactor (SMART), and future nuclear systems such as a very
high temperature reactor system (VHTR) and sodium cooled fast reactor system
(SFR). To effectively support the R&D for new nuclear systems, advanced irradiation
technologies such as high-temperature irradiation, instrumentation, and
long-term irradiation are being developed. In addition, research on the
irradiation characteristics of super-conductor materials and new chemical
materials is being conducted as a part of fundamental research.
