BASKET STRUCTURE OF SPENT FUEL CASK

摘要

PROBLEM TO BE SOLVED: To provide a basket structure of spent fuel cask capable of improving the heat transferring performance from a basket plate to a cylindrical member while preventing deformation of an effective part in the basket plate. ! SOLUTION: In the basket structure of spent fuel cask, plural basket plates 1 are assembled in a glide and piled up. End portions 2 at both ends of the basket plate 1 are inserted into plural grooves 11 which are formed in the inner periphery of the cylindrical member 10. The end portions 2 of the basket plate 1 are formed in a spring shape so as to absorb a reaction force which is generated when the basket plate 1 is heat-expanded while the end portions 2 of the basket plate 1 are in contact with the bottom 12 of the groove 11 respectively. !
