Abstract

Varilla de control auxiliar para ajuste fino de la reactividad de un reactor nuclear, caracterizada porque dicha varilla incluye un apilamiento de pastillas de oxido de circonio contenidas en un revestimiento de un material que tiene una sección eficaz de captura de neutrones apreciable, siendo dicha sección eficaz de captura de neutrones substancialmente inferior a la sección eficaz de captura de neutrones de las varillas de control principales.
