Abstract

BARRA DE AGUA EN DOBLE D PARA HAZ DE COMBUSTIBLE DE 9 X 9 PARTICULARMENTE PARA REACTORES NUCLEARES DE AGUA HIRVIENTE. EN UN HAZ DE COMBUSTIBLE NUCLEAR QUE TIENE UNA PLACA DE UNION INFERIOR, UNA PLACA DE UNION SUPERIORE Y UN CANAL CIRCUNDANTE ENTRE AQUELLAS, SE DESCRIBE UNA BARRA DE AGUA MEJORADA PARA USO PREFERIBLE CUANDO LAS BARRAS DE COMBUSTIBLE SUJETADAS ENTRE LAS PLACAS DE UNION ESTAN COLOCADAS FORMANDO UNA MATRIZ DE 9 X 9. POR REGLA GENERAL, SIETE BARRAS DE COMBUSTIBLE SON OMITIDAS EN EL CENTRO DEL CONJUNTO DE 9 X 9 CON LA FILA MEDIA O QUINTA TENIENDO TRES BARRAS EXTRAIDAS Y ESTANDO BARRAS EMPAREJADAS EN LAS FILAS CUARTA Y SEXTA CON DESPLAZAMIENTO DEL PAR EXTRAIDO HACIA ESQUINAS OPUESTAS. EN EL VOLUMEN CREADO POR LAS BARRAS EXTRAIDAS HAY COLOCADAS DOS BARRAS EN <D> SECCIONADAS, SIENDO CADA UNA DE LAS BARRAS EN <D> REDONDA EN SECCION TRANSVERSAL EXCEPTO EN UNA CUERDA DE TRUNCADO QUE DEFINE LA ESPALDA RECTA DE CADA <D>. EN LA REALIZACION PREFERIDA, UNA DE LAS BARRAS DE AGUA EN <D> ESTA PROVISTA DE LENGUETAS PARA MANTENER LOS SEPARADORES ESPACIANDO LA BARRA DE COMBUSTIBLE A SUS ALTURAS CORRECTAS. ESTA BARRA ES INTRODUCIDA CON UNA ALINEACION QUE PERMITE QUE LAS LENGUETAS PASEN A TRAVES DE LOS SEPARADORES.
