The invention relates to the pressure vessel of a reactor (2) comprising a flow space (8) arranged between the reactor core (6) and a separation device (10) for separating water from water steam, the surface area of the flow section of said space expands upstream the separation device (10), thereby making it possible to pre-separate a water-water steam mixture (G) coming from the reactor core (6). Due to said pre-separation, only the central area is provided with a cyclone device (24), and only drying equipment (26) is disposed near said cyclone device (24). Said invention makes it possible to reduce the height of the pressure vessel of a reactor (2). |
