Abstract

L'invention concerne un dispositif d'obturation (20) d'un orifice interne d'une enveloppe de faisceau d'un générateur de vapeur comprenant un arbre mobile (21) comportant une paire de demi-flasques inférieurs (25, 26), une paire de demi-flasques supérieurs (27, 28) déplaçable par ledit arbre (21) en rotation sensiblement de 180° entre une position basse en regard des demi-flasques inférieurs (25, 26) pour l'introduction dans les orifices des enveloppes du générateur de vapeur et une position haute opposée auxdits demi-flasques inférieurs (25, 26), et des moyens (22) de serrage des demi-flasques inférieurs (25, 26) et des demi-flasques supérieurs (27, 28) sur les pourtours disposés de part et d'autre de l'orifice interne pour obturer cet orifice interne.
L'invention concerne également un procédé d'obturation ainsi qu'un outillage de pose et de dépose du dispositif d'obturation.
