Abstract
Abstract A gas-cooled high temperature reactor is equipped with a supporting structure for the reactor core having a gas conduit passing through the support structure from a hot gas collecting space beneath the supporting structure. The supporting structure itself rests on a floor plate in a columnar arrangement. The floor plate also rests on support columns and possesses a disk-like center portion indirectly supporting the reactor core and an outer annular portion supporting a lateral thermal shield around the reactor core.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
180 words
A gas-cooled high temperature reactor arrangement inside a prestressed cylindrical pressure vessel comprising: a reactor core; a floor plate comprising a disk-like center member and an annular outer member; a core support structure resting on said disk-like center member and in supporting communication with said reactor core; a lateral thermal shield surrounding the sides of said reactor core and resting on said annular outer member; a plurality of elongated support members securely fastened at one end to said disk-like center member and at the other end to the prestressed pressure vessel; a plurality of columnar support members resting on the prestressed pressure vessel at their lower end and in supporting communication with said annular outer member at their upper end; and means for movably supporting said annular outer member on said plurality of columnar support member; wherein said elontated support members are capable of bending, in response to stresses in the direction radial to the central axis of the reactor core while remaining rigid in response to stresses in the direction tangential to the central axis of the reactor core.
Claim 2
Dependent Claim
180 words
A gas-cooled high temperature reactor arrangement inside a prestressed cylindrical pressure vessel comprising: a reactor core; a floor plate comprising a disk-like center member and an annular outer member; a core support structure resting on said disk-like center member and in supporting communication with said reactor core; a lateral thermal shield surrounding the sides of said reactor core and resting on said annular outer member; a plurality of elongated support members securely fastened at one end to said disk-like center member and at the other end to the prestressed pressure vessel; a plurality of columnar support members resting on the prestressed pressure vessel at their lower end and in supporting communication with said annular outer member at their upper end; and means for movably supporting said annular outer member on said plurality of columnar support member; wherein said elontated support members are capable of bending, in response to stresses in the direction radial to the central axis of the reactor core while remaining rigid in response to stresses in the direction tangential to the central axis of the reactor core.
