要約

540 MWe Indian Pressurized Heavy Water Reactor (IPHWR) coolant channel has two fuel locators, placed in the coolant channel, one at the upstream end and one at the downstream end of the fuel string. Fuel locator body has been suitably tapered at the front to facilitate the conversion of radial flow of the coolant to an axial flow parallel to the fuel bundle. The 3D numerical calculations has been carried out to predict the flow distribution over the fuel locator and to understand the flow profile at the fuel locator exit, using the CFD technique. The study has been carried out using commercial CFD software PHOENICS [1]. The result of the study shows that the flow profile at the fuel locator exit is almost uniform and confirms the design objective of the fuel locator.
