Underwater plasma-arc cutting
This report describes the work and experiments carried out to develop an underwater plasma-arc cutting technique, to characterise the aerosols given off during cutting operations on radioactive and non-radioactive objects and to develop adapted filtration and ventilation techniques. The research aimed more specifically at remote and automated cutting of complex, thick metal structures, evaluating the physico-chemical state of the water and achieving minimum generation of sub-products of cutting. It is concluded that thicknesses of 120 to 150mm of stainless steel could be attained underwater. By replacing the existing ball-bearing guidance system with a system of sensors, the problem of orientation would be solved, thus permitting cutting of surfaces without limitations on gradient.
