CAPSULE FOR TRANSPORTATION AND STORAGE OF USED ABSORBING RODS OF CONTROL AND PROTECTION SYSTEM Russian patent published in 2020 - IPC G21F5/00 

FIELD: nuclear energy.

SUBSTANCE: capsule for further transportation and / or long-term storage of spent absorbing rods of control and protection system (CPS AR), in which CPS AR in amount of up to three pieces are arranged vertically so that axes of absorbing elements (AE) are parallel to axis of capsule. CPS AR are arranged with turning angle in plane perpendicular to axis AE. Inside the capsule case there is a retainer with coaxial shells of larger and smaller diameter. First CPS AR has, as a supporting surface, lower planes of CPS AR head ribs connecting the central part of the head with AE of external radius. Second and third CPS AR in vertical plane are supported by central part of head on previous CPS AR. In the plane perpendicular to axis AE, vertically arranged plates are used in structure of stop. Each CPS AR is fixed by contact of the AE entering it with the side surfaces of the plates, and the arrangement of the plates is selected so that each CPS AR is fixed against rotation in both of the two directions.

EFFECT: invention provides maximum use of the useful volume of the capsule for storage of spent CPS AR.
