Tsing Hua Open Pool Reactor(THOR)

The major task of the Nuclear Reactors Division is to operate and maintain the Tsing Hua Open-pool Reactor (THOR) and to ensure uninterrupted services for neutron irradiation, personnel training, and radioisotope production. To make these services constantly available, this division offers irradiation facilities, peripheral research equipment, and supporting staff to those who are interested in nuclear related activities. In addition to running the THOR, neutron activation analysis, neutron radiography, and ageing management for nuclear reactors are also major research activities in this division.
