摘要

Protection device of the control mechanisms of control Rods in a nuclear reactor during testing.The clusters of control Rods are driven by external mechanisms through Connecting pieces introduced in crankcases and guided tour of the Tank cover, which is made during the tests of the primary Circuit, the bottom of which ends in Cuba, a Filter amovibl And set in the dished End (18) of the Carter (17), detachable manner.The Filter is formed by a Crown Holder (20) and (21) of a Ring Maintenance that are trapped between the four meshes (22, 23, 24, 25) filter mesh, with the Order of 5.6 mm, 1 mm and 0.5 mm, respectively.
