INTEGRAL WATER-WATER NUCLEAR REACTOR Russian patent published in 2013 - IPC G21C1/32 

FIELD: power engineering.

SUBSTANCE: integral water-water nuclear reactor comprises a vessel (1) with a composite cover, which consists of a central part (2) and a circular peripheral part (3). In the cavity of the vessel (1) there are sections (5) of a steam generator with pipelines (6) of steam and water, stretching via holes made in the circular peripheral part (3) of the cover. Between the cover and the sections (5) of the steam generator there is a plate (7) with a shell (8). The shell (8) is installed on the plate (7) and is connected with it in a non-detachable manner, and in a detachable manner - with the circular peripheral part (3) of the cover. The plate (7) is made with holes, at the same time steam generator sections (5) are with the upper part installed in the specified holes and are connected to the plate (7) in the detachable manner.

EFFECT: improved strength properties of a reactor due to reduction of stress risers in a cover, reduced time for performance of assembly and disassembly works with simultaneous increased quality of their completion.
