Abstract
UN DISPOSITIVO DETECTOR DEL NIVEL DE POTENCIA DE FLUJO DE NEUTRONES EN EL EXTERIOR DEL NUCLEO INCLUYE UN SUBDISPOSITIVO DETECTOR DE FLUJO DE NEUTRONES (40) Y UN SUBDISPOSITIVO MODERADOR (52) QUE TIENE LA FORMA DE UN BOTE DE DOBLE PARED (52) DE UNA SECCION DE CORTE ANULAR PARA RECIBIR EL SUBDISPOSITIVO DETECTOR (40) EN UNA FORMA COAXIAL Y TELESCOPICA EN EL INTERIOR DEL MISMO Y QUE TIENE UN MATERIAL MODERADOR (56) PREFERIBLEMENTE POLIETILENO DE ALTA DENSIDAD, EN EL ESPACIO ANULAR ENTRE LAS PAREDES DOBLES DEL MISMO PARA CONVERTIR LOS NEUTRONES EPITERMICOS EN FLUJO DE ESCAPE DE UN REACTOR NUCLEAR EN NEUTRONES TERMICOS QUE TENGAN UN NIVEL DE POTENCIA DETECTABLE MEDIANTE EL SUBDISPOSITIVO DE DETECCION DE FLUJO. UNOS ELEMENTOS ESPACIADORES AISLANTES FIJADOS DE FORMA CONCENTRICA ALREDEDOR Y DESPLAZADOS AXIALMENTE A LO LARGO DE LA SUPERFICIE DEL ALOJAMIENTO CILINDRICO DEL DETECTOR (40) SUMINISTRAN UN SOPORTE ESTRUCTURAL LATERAL Y UNA SEPARACION ENTRE ELLOS ASI COMO UNA AISLACION ELECTRICA DEL SUBDISPOSITIVO DETECTOR (40) DEL SUBDISPOSITIVO MODERADOR.
