Abstract
897,483. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 14 1959 [Aug. 14, 1958], No. 27837/59. Class 39(4). A boiling water reactor supplying steam to a heat exchanger or turbine is surrounded by an annular protective tank filled with water and containing a first group of tubes forming part of a cooling circuit and a second group of tubes, of which the inlet header communicates with the heat exchanger or turbine circuit and the outlet header communicates with the reactor vessel to return to it water condensed in the second group of tubes, the circuit thus formed operating with natural circulation and short-circuiting the heat exchanger or turbine, at least one valve being provided to check the entry of steam from the reactor into the second group of tubes. Fig. 1 shows diagrammatically a boiling water reactor suitable for use on a ship, the reactor vessel 1 containing water 2 in an external reflector and discharging steam through a conduit 3 to a heat exchanger (not shown), water being returned to the reactor through conduit 4. Round the container 1 is a biological shield tank 6 filled with water and containing several layers of metal plates, Fig. 2 (not shown); the water in the tank is cooled by sea water flowing through tubes 8. A second set of tubes 13 in the tank 6 are connected through valves 19, 20 to conduit 3, through a normally open valve 21 to a duct 26 leading to the reflector of the reactor, and through valve 22 to conduit 4. Valve 20 opens automatically if there is excess pressure in conduit 3, and if the reactor stops valves 19 and 20 are opened to short-circuit the heat exchanger through tubes 13, natural circulation being set up through conduit 3, tube 13 and duct 26. To enable the reactor to be cooled when fuel is being replaced a pump 28 is included in a circuit running from the top of tubes 13 to the duct 26 so that water can be pumped from the reflector through duct 26 and pump 28, through tubes 13, and through valves 22 (valve 21 being closed) to conduit 4 and into the reactor. The sets of tubes 8, 13 may be separated inside the tank 6 by partitions provided with apertures at the top and bottom, Fig. 2 (not shown).
