Integrated type sodium cooled nuclear reactor, has solid steel skirt fixed under lid and concentric to sodium rotation vessel, where skirt plunges sodium inside rotation vessel with variation limited by operating conditions

摘要

The reactor has a connection device arranged between an upper wall of a sodium rotation vessel (3) with increasing temperature, and a lid (2) fixed at a top of a safety vessel (1), where the rotation vessel is placed on bottom of the safety vessel. The lid is traversed by apparatuses ensured for cooling, controlling and recharging of a nuclear core. A solid steel skirt (11) is fixed under the lid and concentric to the rotation vessel, where the skirt plunges sodium inside the rotation vessel with a variation limited by operating conditions.
