Abstract
EL EQUIPO PROPUESTO ABARCA UNA ANTECAMARA (30) LOCALIZADA DEBAJO DEL RECIPIENTE (4) DE PRESION DE REACTOR Y CONECTADA POR MEDIO DE UN CANAL (36) A UNA CAMARA (34) DE EXPANSION. COLOCADA POR ENCIMA DE LA ENTRADA AL CANAL (36) SE DISPONE DE UNA MAMPARA O DE UNA PARTICION (38) QUE SE DESTRUYE MEDIANTE LOS PRODUCTOS DE FUSION DEL REACTOR DENTRO DE UN INTERVALO DE TIEMPO PREDETERMINADO DESPUES DE LA LLEGADA DE LOS PRODUCTOS DE FUSION. UNA RECIPIENTE (50) DE ENFRIAMIENTO ESTA CONECTADO A LA CAMARA (34) DE EXPANSION, SIENDO CERRADA LA CONEXION MEDIANTE UN ELEMENTO (48) DE CIERRE QUE SE DESTRUYE TAMBIEN POR LOS PRODUCTOS DE FUSION. SI SE DESTRUYE EL ELEMENTO DE CIERRE, POR EJEMPLO PORQUE LLEGA A FUNDIRSE O REVENTAR, EL REFRIGERANTE FLUYE SOBRE LOS PRODUCTOS DE FUSION EN LA CAMARA (34) DE EXPANSION Y LOS PRODUCTOS DE FUSION SON DE ESTA FORMA ENFRIADOS DE MANERA EFICIENTE.
