Parameters to determine the reactor performance

Nishitani, Takeo; Tobita, Kenji

According to the reactor feasibility, minimum requirements, lifetime of each component and availability of the reactor are discussed. About the tritium breeding ratio which is a key factor for the fuel reproduction, coverage of the blanket is discussed not only by geometric coverage but also neutronics effects. As the lifetime of each component, radiation damage of the superconducting magnet, erosion of the armor material, radiation damage of the blanket structural material and burn-up of the tritium breeding material are discussed.
