The RM method, newly proposed here, is aimed at (i) enhancing the modularity of the TA RM and (ii) keeping the compatibility with the materials irradiation tests, compared to the preceding TA RM design of International Fusion Material Irradiation Facility (IFMIF). A 3-dimensional kinematics simulation indicates that the clearance of 50 mm between the TA and high flux test module (HFTM) brings the independent removal from and installation in the test cell, regardless of the presence of the test modules in the test cell. A neutronics performance of the HFTM with the enlarged clearance is also studied. The gradient of the calculated neutron irradiation damage is found to be decreased and satisfies a users’ requirement of the irradiation environment when the clearance is enlarged from 2 to 52 mm. These simulation results suggest that the proposed TA RM method will enhance not only the modularity of the TA, but also improve the materials irradiation test environment., The 30th Symposium on Fusion Technology (SOFT 2018)}, title = {A sophisticated remote maintenance method for the target assembly of Advanced Fusion Neutron Source}, year = {2018} }
