A method for cooling a seal located in a wall of a chamber. The seal being heated by hot pressurized vapor that leaks through a labyrinth into the chamber (20) and internal friction. The method comprising the steps of a) providing a chamber in which the seal is located and into which the hot pressurized vapor leaks, b) injecting cool liquid into the chamber, and c) cooling and condensing the hot pressurized vapor in the chamber. The method is used in a power plant that includes a vaporizer (12), a condenser (16), a cycle pump (18).
L'invention concerne un procédé de refroidissement d'un joint se trouvant dans une paroi d'une chambre. Le joint est chauffé par vapeur sous pression chaude qui s'écoule à travers un labyrinthe dans la chambre (20) et par frottement interne. Le procédé comprend les étapes a) d'apport d'une chambre dans laquelle le joint est placé; et dans laquelle la vapeur sous pression chaude s'écoule, b) d'injection d'un liquide frais dans la chambre et c) de refroidissement et de condensation de la vapeur sous pression chaude dans la chambre. Le procédé est mis en oeuvre dans une centrale nucléaire comprenant un vaporisateur (12), un condensateur (16) et une pompe de cycle (18).
