Abstract: A filter electrical connector having a housing and a contact and filtering circuit subassembly. The contact and filtering circuit subassembly has a ferrite block, electrical contacts passing through the ferrite block, and a lead frame and circuit element assembly. The lead frame and circuit element assembly is mounted on the ferrite block and is electrically connected to the electrical contacts.

Abstract: A spacer grid for a nuclear fuel assembly comprises a plurality of sets of plates which are interleaved and mutually interconnected to define cells each for receiving a fuel rod and further comprising a plurality of hairpin springs each carried by and retained on a respective one of the plates and each projecting into at least one respective cell when in released condition. Each spring is provided with one or two retention spurs arranged for retaining it temporarily in a retracted condition with respect to the respective plate. The retention spurs are releasable by a force of predetermined direction applied on the spring.

Abstract: The apparatus comprises a pole (32), a C-shaped frame (34) fastened to one end of the pole (32) and having two branches (35, 36) substantially parallel to one another and an adjoining part (37) between the two branches, an extraction screw (40) engaged in an internally threaded hole passing through one branch (35) of the frame (34) and having one end forming a punch (50) directed towards lthe inside of the frame (34), and a means (43) for the remote actuation of the extraction screw (40) by screwing or unscrewing. The apparatus also possesses a centring ring (47) arranged round a smooth part of the extraction screw located between its threaded part and its end (50) forming the punch. Unscrewing is carried out by exerting a torque about the axis of the screw (16a) to be extracted, by means of the pole (32) and the frame (34), after the extraction screw has been tightened.
