Abstract
In the framework of the activities foreseen for PRIMA (Padova Research on Injector Megavolt Accelerated) the MITICA neutral beam injector plays the role of main experiment, aiming to build, operate, test and optimize a full power and full scale prototype of the ITER Heating Neutral Beam Injector [1–3].The entire MITICA system will be housed in special buildings, suitably designed to provide all the necessary supports, interfaces and shielding walls for nuclear radiation safety. Therefore an integrated design of the MITICA system and relevant buildings shall be developed and verified carefully, considering all the different configurations, operational modes and load combinations.This paper presents the numerical models and the results of MITICA assembly integrated analyses. The model takes into account properly constraints to ground and surrounding buildings, to study and verify the static and seismic response of the whole assembly.The load cases are defined and the numerical analyses described. Load definition and analyses have been performed considering the requirements of both the ASME [4] and the National Standard NTC2008 [5] for the seismic verification of structures subject to design response spectra.The obtained results are finally shown in detail and discussed, also comparing some different design options for design optimization.
