A laser-based cutting technique is able to reduce hazardous waste leakage by up to 95%, giving it application in the decommissioning of nuclear reactors. Researchers at Lazer Zentrum Hannover (LZH) developed and validated the process, successfully dismantling reactors underwater.
In direct dismantling, a reactor’s components are disassembled on site within the cooling water. What makes the method developed by the Underwater Technology Group at LZH so effective is that in laser cutting, the melt from the joint remains attached to the sheet during the cutting process.
