Abstract

DETECTOR FIJO EN EL NUCLEO, BIMETALICO, CON ENERGIA PROPIA Y PROCEDIMIENTO PARA SU CALIBRACION. LA PRESENTE INVENCION ES UN ENSAMBLAJE DE DETECTORES DE UN REACTOR NUCLEAR QUE INCLUYE UNOS SEGMENTOS DE DETECTORES DE PLATINO (30-40) DISTRIBUIDOS AXIALMENTE, EXTREMO A EXTREMO, EN EL INTERIOR DE UN ENSAMBLAJE DE UN REACTOR ASI COMO UNOS SEGMENTOS DE DETECTORES DE VANADIO (42-52) CONGRUENTES ESPECIALMENTE EN EL MISMO ENSAMBLAJE. LOS DETECTORES DE VANADIO CALIBRAN LAS SEÑALES DE LOS DETECTORES DE PLATINO PARA ELIMINAR LAS CONTRIBUCIONES AL FLUJO QUE CAUSAN LOS PRODUCTOS DE FISION. UN DETECTOR DE VANADIO DE LONGITUD COMPLETA (62) Y UN DETECTOR DE PLATINO DE LONGITUD COMPLETA (90) SE PUEDEN SUBSTITUIR Y UTILIZAR PARA LA DETERMINACION DE LA COMPENSACION DE LOS SEGMENTOS DE DETECTORES DE PLATINO (30-40). LAS SEÑALES COMPENSADAS DEL DETECTOR DE PLATINO, EN DONDE LA COMPENSACION CONSISTE EN EL AISLAMIENTO DE LA PORCION DE LA SEÑAL COMPLETA DEL DETECTOR DE PLATINO QUE ES DIRECTAMENTE PROPORCIONAL A LA VELOCIDAD ACTUAL LOCAL DE DEPOSICION DEL CALOR EN EL COMBUSTIBLE DEL REACTOR, SE PUEDE USAR CON EL PROPOSITO DE LA PROTECCION DEL NUCLEO DEL REACTOR.
