Irradiation Engineering Section of the Neutron Irradiation and Testing Reactor Center was organized to development the new irradiation technology for the application at JMTR re-operation. The new irradiation engineering building was remodeled from the old building for RI development, and will be used from the end of September, 2008. Advanced in-situ instrumentation technology (high temperature multi-paired thermocouple, ceramic sensor, application of light measurement), Mo production technology by the new Mo solution irradiation method, recycling technology on used beryllium reflector, and so on are planned as the development of new irradiation technologies. The development will be also important for the education and training program through the development to young generation in not only Japan but also Asian counties. In this seminar, as the status of the new irradiation technology development, new irradiation engineering building, high temperature multi-paired thermocouple, experiences of light measurement, recycling technology on used beryllium reflector will be introduced.
