The objective of the project was to adapt and qualify the commercial abrasive water-jet cutting technique for application in nuclear decommissioning. Since the cutting has to be remote controlled, methods are required to control the wear of the cutting tool as well as the cutting result. Experiments have shown that sound analysis is not a sufficient method to check the cutting result (cutting through or kerfing only). But in the case of kerfing the reflected jet can be detected by a deflector plate and an adapted accelerometer. Abrasive water-jet cutting produces a small amount of aerosols, especially when cutting under water. It was shown that optimising cutting parameters (to minimise the consumption of water and abrasives) and separating the waste from the water (using a cyclone) can considerably reduce the secondary waste generated. First tests indicate that 80 to 90 % of the abrasives may be recycled.
