Zusammenfassung:	PCT No. PCT/SE97/00046 Sec. 371 Date Jul. 16, 1998 Sec. 102(e) Date Jul. 16, 1998 PCT Filed Jan. 15, 1997 PCT Pub. No. WO97/28536 PCT Pub. Date Aug. 7, 1997The invention relates to a steam blowing tube for nuclear power plants of the kind which has a lower end immersed in a water pool, the purpose of tube being to permit, if required, the blow down of steam into the water of the pool with the purpose of condensing the same so as to counteract the build-up of damaging steam overpressure in the containment of the reactor. A number of through holes are recessed in the wall (11) of the individual blow down tube (10) which each one is delimited by upper and lower edges (13, 14) of which at least one constitutes part of a portion (15) bent in relation to the tube wall (14). The lower hole edge (14) forms a steam flow cutting edge which, when the steam rushes down through the tube, divides a part flow from the main steam flow and brings said part flow out into the surrounding water of the pool before the main flow reaches the bottom opening (12) of the tube.
