A device for cooling a reactor positioned in a vessel. The vessel comprises a water space and a steam space. Cooling pipes that convey evaporating water extend through the reactor. The pipes communicate outside the reactor with the water space at the intake end and with the steam space at the outflow end. The object is to prevent local excess cooling that would interfere with the reaction. A fresh-water preheating section is positioned inside the steam space. The preheating section communicates with an inflow outside the vessel and with an outflow inside the steam space. The preheating section also has open pipes extending through it from top to bottom into the steam space.
