Abstract
The core tank of a liquid metal cooled fast breeder reactor of the pool kind has thermal insulation cladding its inner wall surface. The thermal insulation comprises a plurality of spaced layers of stainless steel sheet material each layer comprising rectilinear panels in spaced array in vertical and horizontal rows. Closure members of cruciform shape close the spaces between adjacent panels.
Claims7
A nuclear reactor construction comprising a wall and thermal insulation cladding a surface of said wall,
- the thermal insulation comprising a plurality of spaced layers of material lying substantially parallel to the wall surface,
- each layer of material comprising a plurality of rectilinear panels secured to the wall surface in spaced array in vertical and horizontal rows, and
- closure members for the spaces between the panels, said closure members being cruciform in shape, the edges of adjacent panels being received in elongate channels formed by the longitudinal edges of the arms of the cruciform-shaped closure members whereby peripheral face regions of both sides of each panel in an array are overlapped by the sides of the channels, the cruciform members and panels being stacked and arranged so that successive superposed arms of a stack of cruciform members overlap peripheral regions of both faces of successive panels in an adjacent stack, the panels being spaced from the walls and bases of the channels thereby to create labyrinth barriers to fluid flow through the spaced layers.
