| 摘要 |
The invention relates to a method for loading and unloading a core of a pressurised water reactor. According to said method, a force (F) acting transversally to the axial direction (57) of a fuel element (50) of the core is exerted against said fuel element (50), which is adjacent to an unloading or loading fuel element position (52), in an upper region of the fuel element (50), by means of a device. The device used is a submersible vessel (2) that can be freely manoeuvred under water, and on which an extensible carrier arm (22, 24) is arranged, said arm being at least indirectly positioned against the fuel element (50). ® KIPO & WIPO 2009
