Title: Improvements in or relating to nuclear reactors
IPC: G21C3/08
Filed: 1956-02-16
Abstract: 794,614. Nuclear reactors. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Feb. 16, 1956 [Feb. 16, 1955], No. 4868/56. Class 39(4). A nuclearreactor in which heat energy is transmitted from bars of fissionable material to a utilising apparatus by a liquid boiling in contact with the bars, is characterised in that the surface of the bars is formed with large corrugations or protuberances which are so shaped and dimensioned that calefaction is avoided. (By " calefaction " is meant the loss of thermal contact between the liquid and the bars which occurs if the temperature of the bars exceeds the boiling point of the liquid by more than a few tens of degrees). The bars may be of cylindrical form and arranged vertically, and may be provided with triangular pins as shown in Fig. 1a. Alternatively, Fig. 1b (not shown), the bars may be arranged horizontally and provided with pins of triangular cross-section arranged circumferentially round the bars. In another arrangement, Fig. 2a (not shown), the bar is provided with transverse constrictions separating substantially spherical masses. Fig. 2b shows a bar around which is wound a rib of semi-circular section ; adjacent turns of the rib may be in contact, Fig. 2d (not shown). The bar may be in the form of a spring with thick well-separated turns, Fig. 2c (not shown). In another arrangement, Fig. 2e (not shown), a cylindrical bar is provided with projections of hemispherical form on its surface ; in a modification of this arrangement, Fig. 2f, each projection is in the form of a frustum of a pyramid with rounded angles. Fig. 3 shows a reactor system in which the reactor 1 is in direct communication with an expansion chamber 2 where the cooling and moderating liquid boils ; the vapour is conducted to heat energy utilizing apparatus 5 where it is condensed and fed back through a pump 7 into the auxiliary circuit 8. The liquid cooled by boiling in the chamber 2 is fed through the conduit 8 and pump 9 back into the reactor. Satisfactory operation is achieved if the rate of flow of the cooling liquid is such that the difference in the temperatures of the liquid in the reactor and in the chamber 2 is less than the difference in temperature of the boiling point of the liquid at the pressures obtaining in the reactor and in the chamber 2, so that vapour formed in the reactor is immediately re-condensed in the liquid. In the arrangement shown in Fig. 4 the reactor is surmounted by a dome 10 containing an inert gas, and the liquid passes through a pressure reducing valve to a separator 12 ; the vapour and the liquid leaving the separator are treated as in Fig. 3. The pressure of the inert gas in the dome should be such that the difference between the temperature at which the liquid would boil in the dome and the temperature of the liquid in the reactor is higher than that necessary to ensure immediate condensation in the liquid of vapour formed in the reactor. The coolant and moderator may be water or heavy water.
