ABSTRACT:
A forged core plate fabricated from a single piece stainless steel forging is described. The plate has a substantially circular shape and penetrations are provided in the core plate to allow passage of control rod blades into the core and direct recirculation flow past the fuel assemblies. The penetrations are formed from machining "5 holes" per penetration. Particularly, each penetration includes a center through hole to allow passage of the control rod blade and control rod blade guide tube. The through hole has a smaller diameter at the plate top surface to provide a tighter fit to the outside diameter of the guide tube to maintain alignment and minimize flow leakage. The through hole is enlarged at the core plate bottom surface to allow clearance in order to improve the installation and removal of the guide tube. Each penetration also include four peripheral blind holes to direct the recirculation flow into the flow holes located on the sides of the guide tube. The blind holes do not extend completely through the plate. When the guide tube is installed in the core plate, the flow holes in the side of the guide tube is located approximately 1/3 of the way down from the plate top surface.
