Abstract

Dispositif d'obturation par congélation d'un conduit tubulaire parcouru par un milieu dans une installation de génie nucléaire. Les machoires (22, 23) sont incurvées conformément au diamètre du conduit à obturer par congélation, et sont munies de perçages radiaux (27) par lesquels les chambres (25) alimentées en agent réfrigérant communiquent avec l'atmosphère.Device for sealing by freezing a tubular conduit traversed by a medium in a nuclear engineering installation. The jaws (22, 23) are curved in accordance with the diameter of the duct to be closed by freezing, and are provided with radial bores (27) through which the chambers (25) supplied with refrigerant communicate with the atmosphere.
