Abstract
La présente invention concerne un dispositif (55) permettant de soumettre des sondes à une irradiation dans le c?ur d'un réacteur nucléaire à eau lourde, comprenant : - une pluralité de doigts de réception de sonde (60), chaque doigt de réception de sonde (60) formant un axe longitudinal (L), s'étendant dans le c?ur du réacteur nucléaire, et ayant une structure à double paroi ; et - un système de transport pneumatique (64). Le dispositif (55) comprend en outre une tête (62), à laquelle les doigts de réception de la sonde (60) sont fixés, comprenant un corps (80) formant, pour chacun des doigts de réception de la sonde (60), un conduit de gaz (113) destiné à recevoir un flux de gaz sous pression provenant du système de transport pneumatique (64), chaque conduit de gaz (113) ayant une première extrémité (115) s'ouvrant dans un espace annulaire (72) entre un tube intérieur (68) et un tube extérieur (70) du doigt de réception de sonde respectif (60) et une seconde extrémité (117) reliée à un orifice d'alimentation en gaz (119) destiné à être raccordé à une alimentation en gaz sous pression, les conduits de gaz (113) des différents doigts de réception de sonde (60) étant fluidiquement séparés les uns des autres.
