Abstract

SE DESCRIBE UN SISTEMA DE DETECCION DE FUGAS (100) Y UN METODO PARA DETECTAR FUGAS DE UN CONTENEDOR (70). EL SISTEMA INCLUYE UNA CAJA (120) QUE DEFINE EN SU INTERIOR UNA CAVIDAD (130) RODEANDO EL CONTENEDOR, EL CUAL PUEDE SER UNA VARILLA DE COMBUSTIBLE NUCLEAR (70) QUE LLEVA PRODUCTOS DE FISION (90) FUGANDOSE A TRAVES DE UNA HENDIDURA (110) EN LA SUPERFICIE EXTERIOR (75) DE LA VARILLA. VARIAS VARILLAS DE COMBUSTIBLE SE EMPAQUETAN JUNTAS PARA DEFINIR UN MONTAJE DE COMBUSTIBLE. LOS PRODUCTOS DE FISION SON CAPACES DE ADHERIRSE A LA SUPERFICIE EXTERIOR DE LA VARILLA DE COMBUSTIBLE YA QUE SE FUGAN A TRAVES DE LA BRECHA EN LA MISMA. UN DETECTOR DE RADIACION (160) ESTA EN COMUNICACION CON LA CAVIDAD TARA DETECTAR QUE LOS PRODUCTOS DE FISION SE FUGAN A TRAVES DE LA BRECHA. ADEMAS, UN INYECTOR DE GAS (370) ESTA EN COMUNICACION CON LA CAVIDAD PARA INYECTAR UNA MULTIPLICIDAD DE BURBUJAS PORTADORAS DE GAS (400) AL INTERIOR DE LA MISMA Y ELIMINAR ASI, LOS PRODUCTOS DE FISION QUE SE ADHIEREN A LA SUPERFICIE EXTERIOR DE LA VARILLA DE COMBUSTIBLE Y TRANSPORTAR LOS PRODUCTOS DE FISION ELIMINADOS POR EL HACIA EL DETECTOR DE RADIACION. DE ESTA FORMA, EL DETECTOR DETECTA LA FUGA DE LOS PRODUCTOS DE FISION INCLUSO AUNQUE ELLOS PUEDAN TENDER A ADHERIRSE A LA SUPERFICIE EXTERIOR DE LA VARILLA. ADEMAS, SE CONECTA UN ELEVADOR (440) AL MONTAJE DE COMBUSTIBLE PARA ELEVARLO DENTRO DE LA CAVIDAD, DE FORMA QUE LA PRESION EXTERNA QUE ACTUA CONTRA LA SUPERFICIE EXTERIOR DE LAS VARILLAS, SE REDUZCA PARA ALIVIAR LA PRESION INTERNA EN LAS MISMAS. CUANDO EL MONTAJE DE COMBUSTIBLE SE ELEVA, LOS PRODUCTOS DE FISION QUE TIENDEN A "OCULTARSE" EN LAS VARILLAS DE COMBUSTIBLE SE EXPANDEN Y SALEN A TRAVES DE LA HENDIDURA. CUANDO LOS PRODUCTOS DE FISION SALEN A TRAVES DE LA HENDIDURA, SON TRANSPORTADOS POR LAS BURBUJAS PORTADORAS DE GAS HACIA EL DETECTOR DE RADIACION DONDE SON DETECTADOS POR ESTE. DE ESTA MANERA, PUEDEN LLEGAR A DETECTARSE FUGAS EN VARILLAS DE COMBUSTIBLE INDETECTABLES DE OTRA FORMA.
