Fast breeder nuclear reactor.

摘要

A fast breeder has a driver core region (12) enrached with a fissile material and a blanket core region (15) containing mainly a fertile material. The driver core region (12) includes an inner core region (13) and an outer core region (14) surrounding the inner core region. The volume of the inner core region (13) is selected to range between 30 and 70 % of the volume of the driver core region (12). The enhancement of the fissile material in the inner core region (13) ranges between 30 and 80% of the fissile material in the outer core region (14).
