Support device on a pressure vessel, in particular a reactor pressure vessel, against horizontal forces

摘要

In a supporting device on a pressure vessel, in particular a reactor pressure vessel (RDB), a guide stem (2) pointing downwards and guided in a fixed support tube (3) is provided on the bottom calotte shell of the pressure vessel in its vertical axis (1.1). The support tube (3) is adjustably mounted in the horizontal direction on a base plate (5) set in concrete and can be firmly bolted to the base plate (5). In particular, the support tube (3) has a plate-shaped supporting foot (3.1) for mounting on the base plate (5). The pressure vessel (RDB), normally supported in the plane (normal to the axis) of its main coolant nozzle, can be effectively supported against horizontal forces by this additional support without impairing the heat motion in its longitudinal axis.
