  • Nuclear reactors
    Patent number: 4046629
    Abstract: Thermal insulation for a core tank of a fast breeder nuclear reactor comprises a plurality of spaced membranes defining a series of concentric chambers lining the tank. Liquid metal is pumped from the cooler regions of a pool of coolant into the first chamber from which it flows successively through the remaining chambers towards the reactor core.
    Type: Grant
    Filed: June 23, 1976
    Date of Patent: September 6, 1977
    Assignee: United Kingdom Atomic Energy Authority
    Inventors: John Graham Durston, John Richard Hind
  • Suspended nuclear reactor containments with reduced thermal stress
    Patent number: 4022656
    Abstract: A containment for a nuclear reactor has a primary vessel for containing the reactor core and liquid coolant. The primary vessel is suspended by its rim from the roof of the containment structure. To reduce thermal stress at the suspension joint, cooling means is provided for the upper peripheral regions of the primary vessel. The cooling means comprises an annular tank containing liquid metal and heat-exchange coils, thermal insulation of varying thickness and a cooling jacket for the thermal insulation.

  • Liquid metal cooled nuclear reactors
    Patent number: 3945883
    Abstract: A fast reactor core is submerged in a pool of liquid metal coolant and there is a catchment tray for falling fuel debris disposed beneath the core. The catchment tray comprises a complex of open top collecting vessels arranged on lattice pitches in layers, the lattice pitches of the layers being off-set to provide a complete catchment area.
