[en] According to the present invention there is provided an improved arrangement for supporting a reactor vessel within a containment structure against static and dynamic vertical loadings capable of being imposed as a result of a serious accident as well as during periods of normal plant operation. The support arrangement of the invention is, at the same time, capable of accommodating radial displacements that normally occur between the reactor vessel and the containment structure due to operational transients. The arrangement comprises a plurality of vertical columns connected between the reactor vessel and a support base within the containment structure. The columns are designed to accommodate relative displacements between the vessel and the containment structure by flexing. This eliminates the need for relative sliding movements and thus enables the columns to be securely fixed to the vessel. This elimination of a provision for relative sliding movements avoids the spaces or gaps between the retention members and the retained elements as occurred in prior art arrangements and, concomitantly, the danger of establishing impact forces on the retention members in the event of an accident is reduced.

[en] Supporting rings for the support of a pressure vessel designed for a nuclear reactor can be fitted without interrupting concreting jobs. U-shaped recesses are provided in the biological shield designed for the supporting ring. The supporting ring consists of partial segments which are connected at their contact points by means of threaded joints and form a stable unit. It is advantageous to fill up the cavities between the supporting ring and the recesses with compressible material. (UWI)
