A power module assembly includes a reactor core immersed in a coolant and a reactor vessel housing the coolant and the reactor core. An internal dry containment vessel submerged in liquid substantially surrounds the reactor vessel in a gaseous environment. During an over-pressurization event the reactor vessel is configured to release the coolant into the containment vessel and remove a decay heat of the reactor core through condensation of the coolant on an inner surface of the containment vessel.

La présente invention concerne un ensemble de module d'énergie comportant un cur de réacteur immergé dans un caloporteur et une cuve de réacteur contenant le caloporteur et le cur de réacteur. Une cuve interne de confinement à sec submergée dans un liquide entoure sensiblement la cuve de réacteur dans un environnement gazeux. Lors de la survenance de surpression la cuve de réacteur est configurée pour libérer le caloporteur dans la cuve de confinement et dissiper la chaleur de décroissance du cur de réacteur par la condensation du caloporteur sur une surface interne de la cuve de confinement.
