Steam generator of the sodium-water type comprising a primary circuit constituted by an elongated vessel filled with liquid sodium, an inlet zone of the elongated vessel into which the liquid sodium is introduced, an outlet zone of the elongated vessel from which the liquid sodium is removed, and a secondary circuit constituted by a plurality of water circulation tubes extending to the inside of the elongated vessel. Inside the elongated vessel is arranged a tank open only downwards, immersed in the sodium contained in the vessel, and at least partly filled with an inert gas, so as to constitute in the vessel, at the level of the outlet zone of the sodium, an expansion tank for limiting the propagation of a pressure wave resulting from chemical reaction between the sodium and the water. The generator is particularly useful in nuclear power stations. |
