Abstract: The invention relates to a protective device for the actuating mechanisms of the control clusters during tests under pressure of the primary circuit of a nuclear reactor. Before mounting the clusters, each guidance sheath for the parts connecting the clusters with the control mechanisms is provided with a removable filter dismountably fixed at the lower portion of the sheath. The filter is constituted by several metal gauzes. The invention is applicable to pressurized water nuclear reactors.
