Abstract

REACTOR DE EBULLICION. ESTA CONSTITUIDO POR UN CUERPO ACTIVO CON VARIAS UNIDADES DE COMBUSTIBLE (5) QUE SE HALLAN SUSTENTADAS POR UNA PLANCHA DE SOPORTE CORRESPONDIENTE (6), LA CUAL POSEE ORIFICIOS REGULADORES (23 Y 24) DESTINADOS A EFECTUAR LA DESEADA DISTRIBUCION DE LA CIRCULACION DE AGUA DE REFRIGERACION A LAS UNIDADES DE COMBUSTIBLE INDIVIDUALES, DE TAL MANERA QUE LA REFRIGERACION SE ADAPTA AL DESARROLLO DE ENERGIA EN DIFERENTES PARTES DEL CUERPO ACTIVO. LA PLANCHA DE SOPORTE DE UNIDADES DE COMBUSTIBLE (6) ESTA PREVISTA DE CAVIDADES (17) QUE SIRVE A MODO DE MEDIOS DE GUIA PARA LA UNIDAD INFERIOR O DE FONDO (14) DE LAS UNIDADES DE COMBUSTIBLE (5). ESTA UNIDAD INFERIOR O DE FONDO (14) PRESENTA LA FORMA DE UN DIFUSOR (16) DESTINADO A REDUCIR EL EFECTO DE ESTRANGULACION O REDUCCION DE PRESION DEL ORIFICIO REGULADOR (23, 24), DE TAL MANERA QUE SE OBTIENE EL DESEADO EFECTO DE ESTRANGULACION O REDUCCION A TRAVES DEL ORIFICIO REGULADOR (23, 24) Y EL DIFUSOR (16), Y, POR TANTO, DEL FLUJO DESEADODEL AGUA DE REFRIGERACION.
