INTEGRATED-TYPE PRESSURIZED WATER NUCLEAR REACTOR COMPRISING AN INTEGRATED PRESSURIZER

摘要

The present invention relates to a pressurized water nuclear reactor comprising: a shell (100) formed by a vessel (101) integrating the core of the nuclear reactor and a cover (102); a pressurizer (110) built into said shell (100) comprising hydraulic lines (118) connected to external circuits, said cover (102) of the shell (100) forming the upper wall of said pressurizer (110); said nuclear reactor being characterized in that at least one hydraulic line (118) of said pressurizer (110) is formed by: a first line arranged through said vessel (101) of the primary shell (100) and under the plane (P1) for positioning the cover (102) onto said vessel (101); a second line secured to said cover (102); said first line and said second line being suitable for sealingly and detachably fitting into one another when said cover (102) is positioned onto said vessel (101), resilient means ensuring the contact between the ends of the two lines.
