    摘要： A nuclear reactor installation includes a reactor pressure vessel and a reactor core in the reactor pressure vessel. A supporting and protective structure supporting the reactor pressure vessel and surrounding the reactor pressure vessel on the bottom and laterally, has a bottom region and a circumferential wall. A core catcher device for the reactor core has a collecting basin for a core melt being installed below the reactor pressure vessel. The collecting basin has a bottom wall and a jacket wall being respectively separated from the bottom region and the circumferential wall of the supporting and protective structure by a spacing gap. Cooling channels are disposed in the spacing gap at the bottom wall and the jacket wall for exterior cooling of the collecting basin with a cooling liquid. Turbulence bodies are disposed in a surface region of the bottom wall for generating a turbulent flow of the cooling liquid flowing from the inside to the outside over the bottom wall toward the jacket wall. There is also a method for starting and maintaining exterior cooling of a core catcher device of a nuclear reactor installation.

    摘要： A method for installing a sealing ring in a ring groove of an injector, in particular a fuel injector, in which the diameter of the sealing ring is enlarged with the aid of an enlarging tool and is inserted into the ring groove, and the enlarged sealing ring accommodated in the ring groove is reshaped to a predefined sealing dimension with the aid of a calibration tool. For the purpose of shifting a residual ring gap remaining in the ring groove during the reshaping process to the groove flank of the ring groove facing away from the combustion chamber, the reshaping process of the sealing ring is carried out by removing the calibration tool from the fuel injector.
