Device for removing cooling fluid and for locating defective fuel arrays in a nuclear reactor in operation by detection of fission products in the cooling fluid. The device consists of at least two independent locating modules (12, 14) and of sampling pipes (17, 24) associated with each of the arrays and connected to the modules. For each of the arrays of the core, there is at least one adjacent array in contact with the first array via one of its lateral faces, connected by its sampling pipe (24) to a locating module (14) which differs from the module (12) to which the first array is connected by its pipe (17). The device is particularly applicable to fast fission nuclear reactors cooled by liquid sodium.
