Abstract
Apparatus for suspending thermal shielding within a nuclear reactor. The apparatus includes a plurality of horizontally deformable, interconnected links which form a chain and suspend a series of horizontally disposed equally spaced thermally reflective plates from beneath the upper horizontal boundary of a nuclear reactor. The deformable links minimize heat transfer and accommodate both seismic and differential thermal expansion of the reflective plates.
Claims3
Apparatus for suspending thermal shielding within a nuclear reactor, comprising:
- (a) a nuclear reactor having a core wherein heat is produced by nuclear fission and a reactor vessel housing the core and liquid metal coolant and having a deck means which provides an upper horizontal boundary for the reactor;
- (b) a plurality of horizontally disposed thermally reflective plates;
- and (c) a plurality of horizontally deformable chains having interconnected links, said chains being connected to the deck and the reflective plates so that the transfer of heat from the liquid coolant above the reactor core to the deck is substantially reduced and said chains being connected to the lower surface of the deck so that the reflective plates are suspended therefrom.
