Claims

[Scope of Claim for Utility Model Registration] 1. A hermetically sealed enclosing member that has a sealable opening and an inert gas supply nozzle and can hermetically surround a nuclear power component that requires replacement, and a bellows enclosure that accommodates a pedestal for the nuclear power component. , a device for raising and lowering the bellows enclosure, a connecting means for connecting the sealed enclosure member and the bellows enclosure at their open ends, each having an open end through which the pedestal can pass, and upper and lower sides of the connecting means. A nuclear power member exchange device characterized in that a sealing means is provided for making the sealing enclosure member and the bellows enclosure an independent sealing body when the connection is disconnected. 2. A nuclear power component exchange device as set forth in claim 1 of the utility model registration claim, in which work gloves are connected to the sealed enclosing member. 3. A nuclear power component exchange device according to claim 1 of the utility model registration claim, in which the connection means for connecting the sealed enclosure member and the bellows enclosure is a fastener. 4. Utility Model Registration Scope of claims 1 or 3, in the nuclear power component exchange device according to claim 1 or 3, in which the sealing means located above and below the fastener connection portion are connected by magnets.
