Abstract: FRAMATOME Plancher amovible pour intervention à l'intérieur d'une enveloppe telle qu'un pressuriseur de réacteur nucléaire à eau sous pression DU CONTENU TECHNIQUE DE L'INVENTION Le plancher amovible comporte une goulotte (14) comportant un ensemble de manutention et de fixation (18, 19, 14a) à l'une de ses extrémités et une partie de support (14b) en forme de portion de cylindre ouverte latéralement et prolongeant la virole (14a) sensiblement dans sa direction axiale, un arbre de support (16) monté articulé à l'extrémité de la goulotte, un ensemble de bras supports (15) montés sur l'arbre de support (16) de manière pivotante autour de l'axe (29) de l'arbre de support (16) et une pluralité d'éléments plans (17) destinés à reposer sur les bras supports. (15) en position déployée pour constituer un plancher de travail sensiblement dans toute la section droite de l'enveloppe (2). Le plancher amovible est introduit dans l'enveloppe (2) à l'état replié ; les bras (15) constituent un ensemble (30) logé dans la goulotte (14) et l'arbre de support (16) a son axe (29') sensiblement perpendiculaire à la direction longitudinale de la goulotte (14). L'arbre de support (16) et les bras (15) sont ensuite basculés de manière que l'axe (29) de l'arbre support (16) soit confondu avec l'axe (20) de l'enveloppe (2). Les bras (15) sont ensuite déployés par pivotement autour de l'axe (29) de l'arbre de support (16) et les éléments plans (17) sont mis en place sur les bras de support (15) en position déployée. Figure 2.

Abstract: The structure (1) of sleeves and plates which encloses the core of a pressurised water-cooled nuclear reactor is dismantled by cutting while immersed in the pond (9) adjoining the reactor vessel (8). The less radioactive sections are placed in containers (27) of the type used to carry reactor guide tubes when these are replaced, and the more radioactive sections are placed in containers (28) of the type used to carry fuel assemblies. Containers (27,28) are removed from the pool separately. Also claimed is the cutting equipment used in the pool.

Abstract: A jet of abrasive liquid is directed at high speed towards the surface of the element (13) with an angle of incidence lying between 30 and 90 DEG . The jet is moved so as to sweep the inner surface of the element (13). At least two successive machining passes are carried out. The speed of sweeping increases from one machining pass to the next. The device (30), mounted movably in translation and in rotation inside the adaptor (13), consists of a tubular assembly fed with pressurised liquid, on which a nozzle (33) is fixed.

Abstract: A method of continuous welding of a series of tubes to a tube sheet, in which the torch current is decreased to produce partial fading of the arc after completion of the first welding bead, and the torch is then moved to a starting position on a second contour to be welded. A stationary preheat is then effected, and a second weld bead is made by following the second contour to be welded. The process continues until the last bead has been made, whereupon the arc is switched off.
