Abstract: A swirling flow identification apparatus includes an eigenequation calculation section 3 and a swirl axis calculation section 4. The eigenequation calculation section 3, based on velocity data of a fluid at a coordinate point, calculates an eigenvalue through an eigenequation concerning the coordinate point and the velocity data. The swirl axis calculation section 4, if the eigenvalue is a complex number, defines an imaginary part of the complex number as a swirl function, calculates a coordinate point providing a local maximum value in the swirl function and defines the coordinate point providing the local maximum value as the position of a swirling axis of a swirling flow in the fluid. With this, even under the presence of another flow or a plurality of swirling flow, the swirling flow can be adequately identified by using the velocity vector at each of node points (coordinate points).

Abstract: In a nuclear reactor internal structure, generation and promotion of object-downstream separating vortices are suppressed so that coolant uniformly flows in a reactor core and pressure loss of flow of the coolant is reduced so that the flow of the coolant is stabilized. A lower connecting plate 30 arranged in a lower plenum 8 comprises a ring portion 31 in which an arcuate portion 32 and a cut-off portion are alternately formed. An outer peripheral portion of the ring portion 31 is asymmetric relative to a flow direction of main flow and also asymmetric relative to a separating flow generation direction.
