Abstract

SE TRATA EQUIPAMIENTOS INTERNOS (34) DE UN REACTOR NUCLEAR (1) CON AGUA BAJO PRESION QUE CONTIENE UNA REJILLA (35) QUE DELIMITA UN RECINTO (36) INTERPUESTA ENTRE LA PLACA SOPORTE (7) DEL CENTRO Y DEL FONDO DEL DEPOSITO (37). EL RECINTO (36) CONTIENE UNA PARED (38), CONDUCTOS (40) DE CONDUCCION DEL REFRIGERANTE HACIA LOS TRABAZONES, LAS PARTES TERMINALES DE LOS TUBOS-GUIAS (32) DE DEDO DE GUANTE (62) DE SONDA DE INSTRUMENTACION Y UNA PLACA DE SEPARACION (41) FIJADA A LA PARED (38) PARA DELIMITAR CON LA PLACA SOPORTE (7) UNA CAMARA (42) DE REPARTICION. LA PLACA DE SEPARACION (41) ESTA PERFORADA POR AGUJEROS (43) UNIDOS AL CONDUCTO (40) DE CONDUCCION DEL REFRIGERANTE Y ESTA FIJADA A LA PLACA (7) MEDIANTE MEDIOS DE UNION MECANICOS (44) REPARTIDOS EN LA PERIFERIA DE LA PLACA DE SEPARACION (41) Y QUE DELIMITAN ENTRE ELLOS UN PASO DE ACCESO (45) DEL REFRIGERANTE HACIA EL INTERIOR DE LA CAMARA (42).
