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.
- 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: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.
- 4. A handling apparatus of an internal structure of a nuclear reactor according to claim 3, whereinsaid cask has a size sufficient for storage of said internal structure which is a shroud which is separated from said nuclear reactor pressure vessel.
- 5. A handling apparatus of an internal structure of a nuclear reactor according to claim 3, whereina 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.
- 6. A handling apparatus of an internal structure of a nuclear reactor according to claim 5, whereinsaid cask has a size sufficient for storage of said internal structure which is a shroud which is separated from said nuclear reactor pressure vessel.
