A15-4 Overall sizing of a structural cage around the pressure vessel

Overall sizing of a structural cage around the pressure vessel 

The overall sizing of a structural cage around the vessel is illustrated here. The aim of the cage is to absorb the impact of internally originated missiles having an energy corresponding to a steam 

The worst case is discussed, corresponding to a steam explosion with a mechanical energy of 1650 MJ.
