ABSTRACT:
In a blow-off device for limiting excess pressure in nuclear power plants, at least one condensation tube disposed so that a lower outlet end thereof is immersed in a volume of cooling water in a condensation chamber having a gas cushion located in a space above the volume of cooling water, and the upper inlet end of the condensation tube extending out of the volume of cooling water and being connectible to a source of condensing steam or a steam-air mixture, the outlet end of the condensation tube being provided with an insert for smoothing the condensation, said insert comprising wall portions forming storage chambers distributed over the length of said tube outlet end and having overflow edges for the cooling water, whereby a spraying action multiplying the heat-transfer surface between the cooling water and a flow of the steam is releasable at said overflow edges when cooling water received in said storage chambers is alternatingly depleted and replenished due to pressure and water-level fluctuations within the condensation tube induced by condensation.
