A reactor of the heavy-water-moderated, steam-cooled type is designed so that thermal stresses in the steamhandling system are relieved. The reactor comprises inner and outer tanks, the inner tank containg heavy water as modemator and the outer tank containg light water as reflector, with tubes running vertically through the tanks. The tubes in turu are divided into inner and outer portions, the inner for the fuel elements and cooling steam and the outer for a coolant, e.g., CO/sub 2/, to keep the tands at a low temperature. To the tube ends are corrected header tubes constructed with one or more bands in each to take up thermal expansion. In operation, the reactor can be controlled by varying the level of heavy water in the inner tank. (D.L.C.)
