DEVICE AND METHOD FOR REPLACING AN IRRADIATED FUEL ASSEMBLY WITH A NEW FUEL ASSEMBLY IN THE VESSEL OF A NUCLEAR REACTOR, AND NUCLEAR REACTOR INCLUDING SUCH A DEVICE

摘要

A device and a method to replace an irradiated fuel assembly with a new fuel assembly in the vessel of a nuclear reactor. This device includes: means for installing the two fuel assemblies in two containers containing heat transfer fluid, where the first container is filled with the irradiated fuel assembly having just been extracted from the reactor core by a handling arm, and where the second container is filled with the new fuel assembly brought in by a transfer basket, means for positioning both these containers, where the irradiated fuel assembly is accessible by the transfer basket, whereas the new fuel assembly is in a position where it can be taken up by the handling arm, and means for positioning both the fuel assemblies.
