Abstract

CONJUNTO DE GRUPOS DE VARILLAS DE CONTROL PARA UN REACTOR NUCLEAR DE AGUA LIGERA. CONSTA DE UN PRIMER GRUPO DE VARILLAS QUE COMPRENDE VARILLAS DE ABSORCION QUE PRESENTAN UNA IMPORTANTE SECCION EFICAZ PARA LA CAPTURA DE NEUTRONES; Y DE UN SEGUNDO GRUPO DE VARILLAS QUE COMPRENDEN VARILLAS DE ACERO INOXIDABLE QUE PRESENTAN UNA REDUCIDA SECCION EFICAZ PARA LA CAPTURA DE NEUTRONES. LOS TUBOS DE GUIA (11) ESTAN HECHOS GENERALMENTE CON UNA ALEACION DE ZIRCONIO QUE PUEDE ESTAR DOTADA DE UNA REDUCIDA SECCION EFICAZ PARA LA CAPTURA DE NEUTRONES.
