Large LOCA with failure of the recirculation ALFC

Large LOCA with failure of the recirculation (ALFC) 

This scenario assumes a break in the cold leg of the primary circuit with operation of the ECCS in the injection phase (although it could also faU in the recirculation phase). It is assumed that the auxiliary feed-water of the steam generators operates correctly, as well as the fan coolers of the containment. Additionally, it is assumed that one train of the containment spray system operates in the ECCS injection phase.
