Pressurized water reactor having improved calandria assembly
This patent describes an assembly for use in a pressure vessel of generally vertically oriented, cylindrical configuration having at lease one fluid outlet at a predetermined elevation and a fluid inlet, and which accommodates liquid therein under pressure and defines an axially upward direction of liquid flow throughout a portion of the height of the vessel, parallel to the vessel axis, and a radial direction of liquid flow at the predetermined elevation through each fluid outlet thereof. The assembly as mounted within the vessel at the predetermined elevation, receives the liquid flow in the axial direction and turning same to the radial direction and comprising: first and second parallel plates having corresponding, generally circular perimeters, a flanged, cylindrical shell joined at its bottom edge to the first plate and at the flange thereof to the vessel for supporting the assembly at the predetermined elevation within the vessel; a skirt of generally cylindrical configuration, substantially rigid in the axial direction and joined at its opposite, open ends to the perimeters of the respective first and second plates and having an opening aligned with each fluid outlet; plural, axially aligned pairs of first and second mounting holes in the respective first and second plates; plural first hollow tubes disposed in parallel axial relationship within the assembly, and plural first connecting means and plural second connecting means respectively received in the plural first and second mounting holes of the first and second plates and connecting the corresponding upper and lower ends of the plural tubes to the first and second plates in sealed relationship therewith.
