Abstract

LA CONTERA COMPRENDE UN ELEMENTO INFERIOR DE SOPORTE (12) DESTINADO A DESCANSAR SOBRE LA PLACA INFERIOR DEL NUCLEO DEL REACTOR AL NIVEL DE AL MENOS UNA ABERTURA DE PASO DE AGUA DE ENFRIAMIENTO Y UNA PLACA ADAPTADORA (13) DOTADA CON UN MEDIO DE FILTRACION DE DESECHOS (18). UNOS DIFUSORES (30) ENSANCHADOS EN DIRECCION DE LA PLACA ADAPTADORA (13) ESTAN FIJADOS SOBRE EL ELEMENTO DE SOPORTE (12). LA PARED DE LOS DIFUSORES (30) ESTA ATRAVESADA POR AL MENOS UNA ABERTURA (31) QUE PONE EN COMUNICACION EL CUELLO DEL DIFUSOR (30) CON UN ESPACIO DE TRAMPA (32) PARA LOS DESECHOS EN EL QUE LOS DESECHOS DETENIDOS POR EL MEDIO DE FILTRACION (18) SON ASPIRADOS POR LA DEPRESION AL NIVEL DEL CUELLO DEL DIFUSOR (30). LA CONTERA INFERIOR (33) PUEDE SER REALIZADA EN PARTICULAR EN FORMA DE UN ,ALOJAMIENTO, ESTANDO EL ELEMENTO DE SOPORTE (12) CONSTITUIDO POR UNA PLACA ATRAVESADA POR AL MENOS UNA ABERTURA DE PASO DE AGUA (15).
