Abstract

Bei einem Verfahren zum Durchführen von Wartungsarbeiten auf der Sekundärseite eines nuklearen Dampferzeugers, insbesondere zum Inspizieren oder Bergen eines zwischen den Heizrohren (6) eines nuklearen Dampferzeugers (2) befindlichen Fremdteiles (30), wird am Umfang des Heizrohrbündels (4a,4b) eine Führungsbahn (12) angeordnet wird, auf die anschließend wenigstens ein Fahrzeug (16-1 bis 16-6) mit einer auf ihm gelagerten ausfahrbaren Lanze aufgegleist und fernbedient entlang der Führungsbahn (12) in eine Position (41-46) verfahren wird, in der die Ausfahrrichtung der Lanze auf einen sich ins Innere des Rohrbündels (4a,4b) erstreckenden Spalt zwischen den Heizrohren (6) ausgerichtet und mit einem an ihrem freien Ende angeordneten Wartungsgerät, insbesondere ein Inspektionsgerät bzw. Bergewerkzeug fernbedient in den Spalt eingeführt werden kann.

Figure 00000001
In a method for carrying out maintenance work on the secondary side of a nuclear steam generator, in particular for inspecting or recovering a foreign part (30) located between the heating pipes (6) of a nuclear steam generator (2), a guideway is formed on the circumference of the heating pipe bundle (4a, 4b) (12) is arranged, onto which at least one vehicle (16-1 to 16-6) with an extendable lance mounted on it is then run on and moved remotely along the guideway (12) into a position (41-46) in which the direction of extension of the lance is aligned with a gap between the heating pipes (6) which extends into the interior of the tube bundle (4a, 4b) and can be inserted into the gap remotely with a maintenance device, in particular an inspection device or recovery tool, arranged at its free end.
