Abstract

PURPOSE: To enable a large thermal shock not to be exgerted on the wall of a reactor by coolant, by means of setting up a guiding mechanism of the coolant so that the coolant may be dispersed in a fan form at the downstream side of a flow arranging grid of left coolant.
CONSTITUTION: Thermal shock preventive panels 21(aWb) are installed at the upper mechanism 10 of a reactor which is set up at the upper part of a core 6 that coolant introduced from a lower plenum may circulate to an upper plenum 4 vial a fuel assembly. The inner diameters of the thermal shock preventive panels 21(aWd) nearer to an arranging grid 11 become larger than that of distant to the arranging grid, and are arranged coaxially so that the mutual distances mat be expanded according as the inner side surface of a reactor vessel 1. The flow layer are expanded satisfactorily according as the access to the inner side surface of the reactor vessel 1 by means of being possed the coolant passed through the core 6 and the flow arranging grid 11 through each preventive panels 21 (aWb)
