SUPERCRITICAL WATER DISPERSED THE NEUTRON POISON MICRO-PARTICLES USED SCWR EMERGENCY CORE COOLING SYSTEM

摘要

PURPOSE: By irrespective preventing the degradation of the mobility in the supercritical pressure state of the water with the change of polarity the cooling water in which the neutron absorbing material used for the emergency core cooling apparatus of the supercritical pressure water cooling nuclear reactor is uniformly dispersed absorbs the extra neutron which becomes to atom in core from the nuclear fission. CONSTITUTION: The neutron absorbing material(1) used for the emergency core cooling apparatus of the supercritical pressure water cooling nuclear reactor(5) is uniformly dispersed in the cooling water. The neutron absorbing material is composed of the material including one kind or greater selected from the group including boron, gadolinium, and the silver and cadmium.
