Abstract
In order to investigate the accidental behavior of the helium cooled test blanket module and its auxiliary systems, a particular sequence has been selected for the deterministic analyses in the frame of the EFDA licensing task for ITER. This sequence starts from an ex-vessel loss of coolant with simultaneous assumed failure of the plasma shutdown system. This paper presents the study of this sequence with the use of various assumptions and code-dependent modeling (RELAP5, MELCOR and ANSYS). Two different variants of the sequence are analyzed depending on the assumption of the failure of water-cooled component of ITER. The resulting transients show the effect of the exposure of the Be pebble beds on air and on a mixture of air and steam.
