Abstract

1,005,133. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 12, 1964 [July 4, 1963], No. 26641/63. Heading G6C. A liquid moderated reactor has its moderator within a calandria tank which tank has a first group of calandria tubes arranged on a first geometrical lattice for housing pressure tubes containing fuel and coolant, and a second group of calandria tubes defining voids within the moderator and arranged on a second geometrical lattice of the same pitch as the first but displaced therefrom, to provide an overall symmetrical arrangement. The need for such an arrangement of voids in the moderator is economic, and arises as a result of the desirability of using side branch pipes 11 for. coolant connections so as to leave the pressure tube ends 3b free for fuel element changing; it is thus necessary to use a relatively large pitch for the pressure tubes 3. Some of the void tubes 8 may accommodate control and shut-down elements 15, ionization equipment 16 and flux scanning wires 17. The reactor illustrated is moderated by heavy water 14 and cooled by light water, which boils in the pressure tubes 3 containing fuel assemblies 9. The calandria is supported on bearings 13, and the pressure tubes are of three-part construction, having end parts of stainless steel and intermediate core parts of zirconium alloy. The lattices of the pressure and void tubes (Fig. 2, not shown) are each of square form and superimposed to give a composite regular square lattice in which each pressure tube is surrounded by four void tubes and vice-versa. Specification 897,457 is referred to.
