| Abstract: | Single-point response spectrum analysis of neutron shielding module was done to check out structural design scheme under earthquake load. Modal analysis of neutrion shielding module of ITER vacuum vessel was built. By modal superposition with acceleration spectrum of ITER final location in France, security against earthquake load of this structure was analyzed. The results show the validity of this structural design of this neuton shielding of vacuum vessel. |
