Wire saws are used in laboratories to cut fragile crystals, substrates, and other materials. In addition, the technology can be used for disassembling advanced research structures. For example, Bluegrass companies designed and fabricated a diamond wire sawing method to dismantle the Tokamak Fusion Test Reactor for the Princeton plasma physics laboratory,“Based upon the demonstration at PPPL on the TFTR surrogate, the diamond wire cutting technology is superior to the baseline technology for both cost and safety considerations. The combination of void filling with this cutting technology will significantly reduce personnel radiation exposure through shielding, remote operation (normal application of this technology), and radionuclide stabilization”.
