An apparatus for dismantling for heavy water reactor facilities, the apparatus comprising:
- a cutting device configured to divide a calandria of the heavy water reactor facilities into a main shell and a sub-shell;
- and
- a transfer device configured to draw the main shell cut by the cutting device to the outside
- the transfer device includes:
- a fixing unit configured to fix the calandria;
- and
- a transfer unit configured to transfer the fixing unit.
A method for dismantling for heavy water reactor facilities including a calandria including a main shell and a sub-shell, a calandria vault receiving the calandria therein, a pressure tube penetrating an inside of the calandria horizontally, and a calandria tube surrounding the pressure tube, the method comprising:
- removing the pressure tube and the calandria tube;
- opening an upper portion of the calandria vault;
- inserting the transfer device into the calandria vault through an upper portion of the calandria vault to support the main shell of the calandria;
- inserting the cutting device into a pressure tube through portion of an end shield of the calandria through the upper portion of the calandria vault to cut between the main shell and the sub-shell of the calandria;
- and
- drawing the main shell of the calandria to the outside of the calandria vault from an inside of the calandria vault using the transfer device.
