METHOD FOR DRY STORAGE OF SPENT FUEL ELEMENTS IN CONTAINERS AND SHIPPING UNIT FOR CONVEYING SPENT FUEL ASSEMBLIES TO INTERMEDIATE STORAGE SITE

摘要

FIELD: nuclear engineering. ^ SUBSTANCE: proposed method includes loading spent fuel assemblies in metal-concrete container, conveying the latter to intermediate storage site, and holding it on storage sire. Shipping unit for conveying spent fuel assemblies to intermediate storage site has flat-car for carrying vertically mounted container holding spent fuel assemblies. Container is provided with external removable circular supporting member engageable with mating supporting surface of flat-car frame and means for locking container relative to mentioned frame. Shipping unit is provided with jacks for lifting the frame to load spent fuel assemblies in container. Side surface of container body has rigging members in the form of seats on its top and bottom ends. Bottom end of container is installed inside mentioned circular supporting member. Container locking means include radially disposed submersible adjustable stops. ^ EFFECT: enhanced reliability and safety of proposed method and device. ^ 4 cl, 8 dwg
