THE LIGHT-WATER INTEGRAL REACTOR WITH NATURAL CIRCULATION OF THE COOLANT AT SUPERCRITICAL PRESSURE B-500 SKDI

Pressure increase in the primary circuit over the critical value gives a possibility to construct the B-500SKDI (500 MWe) lightwater integra l reactor with natural circulation of the coolant in the vessel with a diameter less than 5 m. The given reactor has a high safety level, si mple operability, its specific capital cost and fuel expenditure being lower as compared to a conventional PWR. The development of the B-500 SKDI reactor is carried out taking into consideration verified technic al decisions of current NPPs on the basis of Russian LWR technology.
