Abstract

UNA REJILLA SEPARADORA PARA ESPACIAR VARILLAS DE COMBUSTIBLE EN UN CONJUNTO DE COMBUSTIBLE DE UN REACTOR NUCLEAR QUE COMPRENDE UNA PLURALIDAD DE TIRAS DE REJILLA ENTRELAZADAS DISPUESTAS EN UNA CONFIGURACION DE HUEVERA, DE MODO DE DEFINIR CELDAS PARA EL ALOJAMIENTO SEPARADO DE CADA VARILLA DE COMBUSTIBLE; LAS TIRAS PARA VARILLA TIENEN, CUANDO MENOS, UN SALIENTE RIGIDO QUE SE PROYECTA DENTRO DE CADA CELDA PARA LA UBICACION DE LAS VARILLAS DE COMBUSTIBLE QUE SE EXTIENDEN EN ELLA, CARACTERIZADA EN QUE LOS SALIENTES DE CELDA EN UN PAR DE TIRAS DE REJILLA ASOCIADAS, QUE NO ESTAN OPUESTAS, ESTAN CERRADAS A LA CIRCULACION AXIAL DEL LIQUIDO ENFRIADOR A LO LARGO DE LA CELDA Y LOS SALIENTES RESTANTES DE LA CELDA EN LAS TIRAS DE REJILLA ASOCIADAS RESTANTES, ESTAN ABIERTOS A LA CIRCULACION LONGITUDINAL DE LIQUIDO ENFRIADOR A LO LARGO DE LA CELDA.
