Abstract

The load carrying capacity of the pressure vessel head to withstand a postulated in-vessel steam explosion has been investigated. Former results have been confirmed and extended. For a quite conservative reference case the mechanical energy release which the head can carry turns out to be at least 1 GJ. The mechanical energy release from in-vessel steam explosions postulated can be expected to be significantly lower, and therefore will not rupture the vessel head and not endanger the containment integrity.

Abstract

The load carrying capacity of the pressure vessel head to withstand an in-vessel steam explosion is investigated. Firstly, as a key problem, the impact of molten core material against the vessel head is studied by model experiments scaled down 1:10. Structural details are considered carefully. The results are converted to reactor dimensions using similarity theory. This approach was checked by simplified liquid-structure impact experiments in different scale. Secondly, the upward acceleration of molten core material is studied by computational models. As results the mechanical energies which the vessel head can withstand are presented.
