IMPROVEMENTS IN OR RELATING TO REACTORS FOR PERFORMING NUCLEAR FISSION REACTIONS
A boiling reactor is designed for improved thermal efficiency of the vapor cycle by superheating. The reactor is arranged for double circulation, whereby saturated vapor is produced at the outer periphery and passed to the interior for superheating. The liquid (usually water) enters from above into an annular chamber between the pressure vessel and an outer duct and flows down the length of the reactor, serving as a reflector. At the bottom, the liquid reaches a second annular chamber between the outer and inner ducts where it is heated by fissile fuel elements. At the top of the chamber, the liqunid is again deflected and reaches the inner duct where tue vapor is superheated. The vapor temperature and pressure may be raised to 600 deg C and 300 atms gage by employing ceramic fuel elements in the superheating region. One advantage of this arrangement is that the pressure vessel is exposed only to tue temperature of the feed liquid. (D.L.C.)
