Section: claims

1. A handling apparatus of an internal structure of a nuclear reactor, comprising: an opening which is opened at a portion of a nuclear reactor building positioned above an upper portion of a nuclear reactor well pool;  a cask for storing said internal structure of said nuclear reactor which is taken from a nuclear reactor pressure vessel in said nuclear reactor building;  a crane for lifting said cask into and out of said nuclear reactor building through said opening; and  a hoisting device which is lifted together with said cask by said crane and is utilized for inserting said internal structure into said cask.  a lifting balance lifted by said crane;  a hoisting device mounted on said lifting balance;  said cask being hung on and supported by said lifting balance;  an inlet port installed at a lower end of said cask;  a cask bottom plate arranged for attachable and detachable installation to said cask and for closing said inlet port of said cask; and  a penetrating hole provided at an upper portion of said cask for passing a rope of said hoisting device therethrough.  said cask has a size sufficient for storage of said internal structure which is a shroud which is separated from said nuclear reactor pressure vessel.  a bougie car for mounting said cask bottom plate is provided so as to run freely on an operation floor in said nuclear reactor building by striding over a nuclear reactor well pool.  said cask has a size sufficient for storage of said internal structure which is a shroud which is separated from said nuclear reactor pressure vessel. 2. A handling apparatus of an internal structure of a nuclear reactor according to claim 1, wherein said internal structure is a shroud which is separated from said nuclear reactor pressure vessel. 3. A handling apparatus of an internal structure of a nuclear reactor according to claim 1, comprising further: 4. A handling apparatus of an internal structure of a nuclear reactor according to claim 3, wherein 5. A handling apparatus of an internal structure of a nuclear reactor according to claim 3, wherein 6. A handling apparatus of an internal structure of a nuclear reactor according to claim 5, wherein
