A method and a device for guiding a coolant flow in a light-water nuclear reactor. The guiding of the coolant flow is performed within a mixing cross section which comprises four orthogonally arranged sub-regions (1, 1a, 1c), in their turn comprising whole or parts of fuel assemblies (1). In each sub-region (1, 1a, 1c) there is arranged at least one level which comprises spacers (7) which are provided with flow control members (12) adapted such that the coolant is guided from one sub-region (1, 1a, 1c) to an adjacent sub-region (1, 1a, 1c), thus equalizing the enthalpy of the coolant in the mixing cross section.
