<p>Device for the Determination of the Vibrations Occurring at the Internals of a Reactor Pressure Vessel In such a device, it is desirable to perform the maintenance of the vibration detector located in a housing (1) from outside the reactor pressure vessel (13). For this purpose, a guide tube (10) is provided, one end of which is fed through an intermediate pipe stub (11) to a receptacle cone (8) connected to the core internals (9). The end (12) of the guide tube (10) facing away from the reactor pressure vessel (13) is cup-shaped and is sealed with a cover (6). A flexible rod (5) is connected to the housing (1) and its other end extends into the cup-shaped end (12) of the guide tube (10). The flexible rod (5) and with it the housing (1) connected to it can be inserted into the receptacle cone (8) through a device located in it. This cone connection provides good transmission of the vibrations prevailing at the internals (9), which reach an evaluation unit through the cable (3).</p> |
