Abstract

EN UNA INSTALACION DE REACTOR NUCLEAR, ESPECIALMENTE EN REACTORES DE AGUA NORMAL, SE HA DISPUESTO UN DISPOSITIVO DE RETENCION DEL NUCLEO (CC) CON UN RECEPTACULO RECOGEDOR REFRIGERABLE (19) EN EL INTERIOR DE UNA CAVIDAD DEL REACTOR (8) Y DEBAJO DEL RECEPTACULO DE PRESION DEL REACTOR (6). EL RECEPTACULO RECOGEDOR (19) DISPONE DE UNA ENVOLTURA (21) QUE SE EXTIENDE AL MENOS HASTA CASI LA ALTURA DEL NUCLEO DEL REACTOR (10), Y UN FONDO (20). ENVOLTURA Y FONDO (20,21) DEL RECEPTACULO RECOGEDOR (19) ESTAN INSTALADOS CON UNA ZONA INTERMEDIA SEPARADORA (28) RESPECTO AL FONDO (7.1) O RESPECTO A LA PARED PERIFERICA (7.2) DE UNA ESTRUCTURA DE SOPORTE Y PROTECTORA (7) DEL RECEPTACULO DE PRESION DEL REACTOR (6). EN LA ZONA INTERMEDIA SEPARADORA (28) SE HAN DISPUESTO CONDUCTOS DE REFRIGERACION (29.1, 29.2) EN LA PARTE DEL FONDO Y DE LA ENVOLTURA, PARA LA REFRIGERACION EXTERIOR DEL RECEPTACULO RECOGEDOR (19), CON UN LIQUIDO DE REFRIGERACION, ASI COMO EN LA ZONA SUPERFICIAL DEL FONDO (20) ELEMENTOS DE TURBULENCIA (34, 34A), PARA PRODUCIR UNA CORRIENTE TURBULENTA DEL LIQUIDO REFRIGERANTE DESDE EL INTERIOR HACIA EL EXTERIOR, A TRAVES DEL FONDO (20) HACIA LA ENVOLTURA (21). EL OBJETO DE LA PRESENTE INVENCION SON EL PROPIO DISPOSITIVO DE RETENCION DEL NUCLEO (CC), UN PROCEDIMIENTO PARA LA PUESTA EN MARCHA Y MANTENIMIENTO DE UNA REFRIGERACION DE EMERGENCIA PARA EL RECEPTACULO RECOGEDOR (19), ASI COMO LA UTILIZACION DE ALETAS DELTA PARA LA GENERACION DE TURBULENCIAS, INSTALADAS EN EL SISTEMA DE REFRIGERACION DE LA ZONA DEL FONDO DEL RECEPTACULO RECOGEDOR (19).
