Title (EN) ASSEMBLY FRAME FOR NUCLEAR FUEL WITH GUIDE TUBES AND METHOD FOR MANUFACTURING SAME
(FR) SQUELETTE D'ASSEMBLAGE COMBUSTIBLE NUCLEAIRE A TUBES GUIDES ET PROCEDE DE FABRICATION D'UN TEL SQUELETTE
Abstract: front page image
(EN)The assembly frame for nuclear fuel has an upper joining piece and a lower joining piece (10) connected by guide tubes (16) for receiving control cluster pencils and containing, in their lower part, a tubular cartridge (20) and each provided with a lower plug (22) resting against the lower joining piece (10), bored by a through hole of a fixing screw (26). The cartridge (20) comprises a lower plug (28) resting against the plug (22) of the guide tube and the phases in line with the two plugs (22, 28) have axial projections mutually co-operating for blocking the two plugs against each other in rotation when the screw (26) is screwed in a threaded hole (32) of the plug of the cartridge (28).
(FR)Le squelette d'assemblage combustible nucléaire a un embout supérieur et un embout inférieur (10) reliés par des tubes guides (16) destinés à recevoir des crayons de grappe de commande et contenant, à leur partie inférieure, une cartouche tubulaire (20) et munis chacun d'un bouchon inférieur (22) en appui contre l'embout inférieur (10), percés d'un trou de passage d'une vis de fixation (26). La cartouche (20) comporte un bouchon inférieur (28) en appui contre le bouchon (22) du tube guide et en ce que les phases en regard des deux bouchons (22, 28) présentent des saillies axiales coopérant entre elles pour provoquer le blocage en rotation l'un contre l'autre des deux bouchons lorsque ladite vis (26) est vissée dans un trou taraudé (32) du bouchon de cartouche (28).
