A cylindrical reactor pressure vessel (1), with pipe nozzle (3) from which pipelines (4) run through wall tubes (15) in a biological shield (6), is supported by retaining tubes (16) which are secured in the wall tube (1) and tightly surround the pipe nozzle (3) from outside. The support is especially suitable for pressurised water reactors. <IMAGE>
