The light water integral reactor with natural circulation of the coolant at supercritical pressure B-500 SKDI

Abstract Pressure increase in the primary circuit over the critical value gives a possibility to construct the B-500SKDI (500 MWe) lightwater integral 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, simple operability, its specific capital cost and fuel expenditure being lower as compared to a conventional PWR. The development of the B-500SKDI reactor is carried out taking into consideration verified technical decisions of current NPPs on the basis of Russian LWR technology.
