1,158,376. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 16 April, 1968 [26 May, 1967], No. 17923/68. Heading G6C. In a fast, sodium cooled, breeder reactor, a settled bed of fuel particles is supported in the core within mesh or sintered containers through which the coolant also flows. The fuel slurry, consisting of fuel particles, in coolant liquid, is introduced into each fuel module through pipe 24, and the particles are deposited in the conical annular space 48 between the mesh screens 50, 52. Coolant flows upwards through the inlet 60 and flows radially through the screens 50, 52. The coolant may be lithium or potassium. During operation, some fuel particles expand from annulus 48 into the separator 32 and downwardly through the inlet pipe 24. Intermittent fluidization is effected, during operation, by injecting carrier liquid or coolant through the manifold 28 and pipe 72 to produce uniform fuel burn-up and plutonium production. The fuel particles may be uranium and/or plutonium in the form of ceramics or dioxides. |
