Post-Fukushima actions

The CAREM prototype design was reviewed considering Fukushima experience. Topics like seismic requirements, loss of heat sink and black-out were considered. The design basis earthquake was reviewed. A risk-based criterion, based in Argentine Regulations AR 3.10.1 and AR 3.1.3, was used. CAREM-25 considers in its design base the loss of heat sink and station black-out during the grace period. Provisions were considered to allow, after the grace period, core decay heat removal and containment cooling using the fire extinguishing system or an autonomous system.
