Abstract
Internal equipments suitable for use in a nuclear reactor comprise a lower plate provided with openings for the coolant leaving the core, an upper plate, support columns connecting the plates together and guides for the vertically movable control clusters. Each guide has an upper section fixed to the upper plate and a lower section extending between the upper and lower plates. The lower section (32) comprises a base bearing on a frusto-conical seat fast with the lower plate and is subjected to the action of resilient means exerting a force pressing the base on the seat.
