Remotely operated equipment: Sodium reactor decommissioning
Application:
Shutdown of a sodium nuclear reactor.
Progress of work:
This machine has been developed and created in order to cut internal and external parts of the reactor in calibrated pieces so that those can be disposed in special containers.
Description:
The whole machine consists of a precision bridge that positions the cutting tools into the right working position in the reactor, and a control desk that is outside of the contaminated area. For the different steps of machining many different parts of this machine are operated by a remote control one after another.
Solution:
This machine centralises itself with the help of 8 hydraulic operated clamping plates. The machining is done via 3 different cutting bits. Four electric operated machining axes for all different cutting positions are available. The tool rotation is hydraulic. Information about the cutting process as well as about any positioning will be shown on a control screen.
