A SUPPORT ARRANGEMENT

摘要

A nuclear reactor includes a reactor pressure vessel (12) and a core barrel (14), contained within the reactor pressure vessel (12). The reactor (10) further includes a single vertical support (16), for transmitting vertical load from the core barrel to the reactor pressure vessel. Further, lateral support means is provided at an elevation which is above that of the support (16) to provide lateral support to the core barrel (14). This arrangement will result in reduced stress arising from the temperature fluctuations.
