Title (EN) CRDM DIVERT VALVE
(FR) VANNE D'AIGUILLAGE POUR CRDM
Abstract:
(EN) A valve for controlling flow of high pressure fluid to a CRDM hydraulic latching mechanism of a nuclear reactor core. The valve includes a valve body having an inlet for receiving fluid from a fluid source, an outlet, and a dump port for dumping fluid backflow. A valve member is movable within the valve body between a first position restricting flow between the outlet and the dump port such that high pressure fluid entering the valve body through the inlet exits the valve body through the outlet, and a second position whereat the dump port is in fluid communication with the outlet such that at least a portion of any backflow fluid flowing back into the valve body via the outlet exits the valve body via the dump port.
(FR) L'invention concerne une vanne servant à commander l'écoulement d'un fluide à haute pression vers un mécanisme de verrouillage hydraulique de CRDM d'un cœur de réacteur nucléaire. La vanne comprend un corps de vanne doté d'une entrée servant à recevoir du fluide provenant d'une source de fluide, une sortie et un orifice d'évacuation servant à évacuer un reflux de fluide. Un élément de vanne peut être déplacé à l'intérieur du corps de vanne entre une première position limitant le débit entre la sortie et l'orifice d'évacuation de telle sorte que du fluide à haute pression entrant dans le corps de vanne par l'entrée quitte le corps de vanne par la sortie, et une deuxième position dans laquelle l'orifice d'évacuation est en communication fluidique avec la sortie de telle façon qu'au moins une partie d'un éventuel fluide de reflux rentrant dans le corps de vanne via la sortie quitte le corps de vanne via l'orifice d'évacuation.
