| Zusammenfassung: | A reactor pressure vessel cover for a boiling water reactor having a cover cooling system has at least one cover spray head disposed on the side facing the interior of the reactor. The cover spray head is fixed to a connector on the reactor pressure vessel cover, through which connector the cooling water of the cover cooling system can be supplied to the at least one cover spray head. The cover spray head is detachably connected to the connector, in that there is a sealing device at the connecting point between the cover spray head and the connector, by which the emission of cooling water into the interior of the reactor is avoided. In addition, with an antirotation device, the position of the cover spray head is prevented from rotating about an imaginary longitudinal axis of the connector. |
