Pena spent nuclear fuel storage

摘要

The invention relates to nuclear power engineering, in particular, to means for storage of spent nuclear fuel elements RBMK-1000 and is intended for use in dry storage of spent nuclear fuel. Proposed pencil comprises a housing with a sidewall and a bottom, a cover lifting device, formed in a mold and the central backup gripping collar taken along periphery of the cover and the grate. In the central fungus installed control valve and the lock rod stub. On the bottom is mounted a shock absorber made in the form of thin-walled concentric shells that are welded to the bottom of the upper ends for damping impact in emergency situations involving a fall of the canister and allow the installation of one canister to another. The upper end of the canister lid backup gripping shoulder is formed at the same level or above welded edges of the central mold and the stub shaft. Shock absorber made of one group of concentric thin shells connected in the bottom of the support ring. The technical result is the removal of the clutch cover canisters and deformation when falling on the canister pencil.
