REACTOR Russian patent published in 2013 - IPC G21C1/00 F28D7/00 

FIELD: power industry.

SUBSTANCE: invention is designed for being used as single-block marine high-duty nuclear power plants with high unit power, which operate in varying load mode. Liquid-metal carrier is used in the proposed reactor. Besides, different arrangement patterns of heat transfer to liquid of the second circuit are located inside the reactor housing. The proposed device includes an integral active zone, a nuclear reaction control system and a protection system, steam generators and heat exchangers, heat carrier pumping pumps, and biological protection. At that, an electromagnetic pump is installed in the heat carrier circuit when heat is being transferred in steam generator; the above pump is coaxially attached to lower part of vertically located steam generator, and in the heat carrier circuit when heat carrier is being transferred in heat exchanger the provision is made for its connection to lower part of heat exchanger by means of a pipeline and location that is parallel to vertically located heat exchanger. Heat carrier flow is arranged in upward direction through active reactor zone.

EFFECT: optimisation of heat exchange in mode of varying loads and obtaining optimum weight and dimensional parameters of nuclear power plants as a whole, being the part of the ship.
