Abstract

The decay heat due to neutron activation in fusion-reactor structural materials, after one year of operation, may potentially cause at least a partial meltdown of the reactor structure. A sector of the ITER fusion reactor was modelled in conditions similar to those after a total LOCA (Loss of Coolant Accident). The purpose was to estimate the temperature histories of the various components after the accidental shutdown. The P-THERMAL finite element code, coupled with PATRAN pre/post-processor were used. Decay heat calculations were performed by means of the ANITA code. The adoption of other structural materials, in place of the reference AISI 316L, was considered, in order to check its effect on this type of thermal transient. However, to avoid non-realistic assumptions, the investigation was restricted to steels.
