Abstract
UN NUCLEO DE REACTOR NUCLEAR (14) TIENE UN PRIMER GRUPO DE VARILLAS DE COMBUSTIBLE (48) CONTENIENDO MATERIAL FISURABLE Y UN ABSORVENTE NO COMBUSTIBLE, Y UN SEGUNDO GRUPO DE VARILLAS DE COMBUSTIBLE (48) CONTENIENDO MATERIAL FISURABLE Y DOS MATERIALES ABSORVENTES COMBUSTIBLES. LOS GRUPOS DE VARILLAS DE COMBUSTIBLE ESTAN DISPUESTOS EN EL NUCLEO PARA CONTROLAR LA POTENCIA EN LAS HORAS DE MAYOR CONSUMO Y UN COEFICIENTE DE TEMPERATURA MODERADOR. EL NUMERO DE VARILLAS DE COMBUSTIBLE EN EL PRIMER GRUPO ES MAYOR QUE EN EL SEGUNDO. LOS DOS MATERIALES ABSORVENTES COMBUSTIBLES PUEDEN SER PROPORCIONADOS COMO REVESTIMIENTOS SEPARADOS (80, 82) O EN UNA MEZCLA (78B). UN MATERIAL ABSORVENTE COMBUSTIBLE ES UN MATERIAL PORTA-ERBIO, TAL COMO OXIDO DE ERBIO Y EL OTRO ES UN MATERIAL PORTA-BORO, TAL COMO ZIRCONIO DIBORIDO. ALTERNATIVAMENTE EL MATERIAL PORTA-ERBIO PUEDE SER INTERESPARCIDO O MEZCLADO CON EL MATERIAL FISURABLE (74).
