A Method for the Calculation of Fuel Cycle Costs of Nuclear Power Plants with Pebble Bed Reactor

Automatic translation: The most important factor in the assessment of a nuclear power plant, apart from safety and availability are its electricity generation costs. Power generation costs can be broken down into plant costs, operating, maintenance and insurance costs and fuel cycle costs. The first-mentioned cost components can be determined using conventional methods, while the determination of fuel costs fuel costs differs significantly from that of conventional power plants. In a nuclear power plant, in addition to the usual fuel reserve, a fuel operating inventory is tied up in the reactor that corresponds to an average fuel requirement of several years. In addition, the fuel consumption costs cannot be clearly calculated from calorific value, efficiency and fuel costs alone. The ''calorific value'' of the uranium used depends on restrictions regarding reactivity thermal stress, radiation resistance and mode of operation.
