A method for manufacturing an electrically conducting article is disclosed. According to some aspects, the method includes dry mixing a powder comprising at least one thermosetting resin, a hardener compound powder for the resin and an electrically conducting filler powder, the thermosetting resin including at least two epoxide groups. The method further includes thermocompressing the mixture of powders in a mold with a shape adapted to the article and at an effective temperature for obtaining cross-linking of the resin.

Method for preparing an electrically conducting article

The invention relates to the use of a composition comprising a chlorinated polyester resin in which the polyester satisfies formula (I) below: together with a crosslinking catalyst and a crosslinking accelerator in order to plug a crack affecting the wall of a metal device intended to contain a radioactive acid material. It is especially applicable in the maintenance of metal equipment of nuclear installations, in particular equipment that is for irradiated nuclear fuel reprocessing.
