Abstract
UN CONJUNTO DE COMBUSTIBLE NUCLEAR QUE INCLUYE UNA CRUZ DE AGUA QUE DIVIDE EL HAZ DE VARILLAS DE COMBUSTIBLE DEL CONJUNTO EN MINI©HACES CADA UNO DE LOS CUALES CONTIENE REJILLAS ESPACIADORAS SEPARADAS AXIALMENTE QUE DEFINEN CELDAS RECEPTORAS DE VARILLA EN LUGARES DE ESQUINA, LATERALES E INTERIORES DE LA REJILLA ESPACIADORA. PARA MEJORAR LAS CARACTERISTICAS DE CHF DEL CONJUNTO DE COMBUSTIBLE, LAS VARILLAS (40A) EN LAS CELDAS DE ESQUINA (58A) DE CADA REJILLA (48) TIENEN DIAMETRO MENOR QUE LAS RESTANTES VARILLAS (40B©C) DEL MINI©HAZ, Y LA TIRA EXTERIOR DE REJILLA (51) TIENE PERFORACIONES FORMADAS EN LAS UBICACIONES DE LAS CELDAS DE ESQUINA Y LATERALES (58A, 58C). ADEMAS, AL MENOS UNA MAYORIA DE LAS VARILLAS TIENE UN REVESTIMIENTO DE VENENO SOBRE LA SUPERFICIE DE RECUBRIMIENTO O SOBRE LAS PASTILLAS DE COMBUSTIBLE, PROPORCIONANDOSE UN MODELO PREDETERMINADO DE ENRIQUECIMIENTO DE COMBUSTIBLE QUE COOPERAN EN ASEGURR QUE LAS ENERGIAS PUNTA DE LAS VARILLAS EN LAS CELDAS DE ESQUINA Y LATERALES DE LOS ESPACIADORES SEAN MENORES QUE LA ENERGIA PUNTA DE LAS VARILLAS EN LAS CELDAS INTERIORES.
