ABSTRACT:
The invention is directed to a method for performing remotely-manipulated rk on a conduit of a nuclear facility. The method of the invention is for maintaining pipe conduits in a radioactively contaminated cell such as a large-area cell of a reprocessing facility for irradiated nuclear fuel. The defective conduit portion to be removed is sawn out of a conduit and a replacement conduit segment is welded into the conduit. In order to provide for rapidly and accurately welding the replacement conduit segment into the conduit, the step of machining the two conduit end portions is combined with the step of determining the inside dimension between the conduit end portions formed by the step of sawing out the defective conduit portion. An apparatus for carrying out the method of the invention is also disclosed.
