| 内容記述 | We have conducted design activities of Advanced Fusion Neutron Source A-FNS in order to perform irradiation tests for fusion materials. We have intended to use A-FNS also for neutron applications because it is an intense neutron source. As one of the applications, we are to conduct medical radio isotope (RI) production such as Mo-99. We have investigated an installation of RI Production Module (RIPM) with a thin plate-like sample for RI production into a gap of a few centimeter between a lithium target and an irradiation module for fusion materials. We have conducted the conceptual design on the RIPM especially by taking the following concerns into consideration: (1) Insertion and ejection of the sample for RI production during irradiation by horizontal transfer between the irradiation test cell and lateral access cell, (2) Cooling of nuclear heating, and (3) Reduction of the radiation streaming. The irradiation tests for fusion materials are performed continuously for a long period over a few months. On the other hand, the period per an irradiation for RI production is a few days. We designed the RIPM with a mechanism by using a servomotor in order to insert and eject the sample for RI production from outside the test cell without stopping a deuteron beam. We introduced helium gas cooling functions to the RIPM to remove the nuclear heating. In order to reduce the radiation streaming through the penetration duct for the RIPM and lessen the radiation level in the lateral access cell, we designed a shielding structure by putting shielding materials such as tungsten in the duct. By using the RIPM, we are also to perform neutron measurement by foil activation method. From the nuclear analyses, it was clarified that a spatial distribution of neutron flux depending on the deuteron beam can be monitored. | |||||
