The pressure rise inside a containment structure of a steam cooled nuclear reactor is limited in the event of a failure of the reactor pressure vessel by a steam condensing system within the structure. As shown, the reactor 1 is surrounded by the containment 4 which also contains the cooling and heat-accumulating packing 5. If pipes 2 or 3 burst, steam flows to the packing 5 and is condensed. Later sprinkler tubes 10, 15 are coupled to the space 8 by the pump 12 and heat exchanger 12.
