Abstract

Procedimiento para la producción de un artículo absorbente de neutrones, caracterizado porque comprende pulverizar con plasma carburo de boro y una sustancia metálica del grupo consiste en metales y aleaciones de metales, sobre un sustrato, de manera que el carburo de boro se deposite sobre el sustrato en una matriz de la sustancia metálica sin oxidación del boro, para producir un absorbedor de neutrones que es estable cuando se expone a un medio de depósito acuoso en el cual se almacenan estanterías de combustibles nuclear agotado con una pluralidad de tales artículos absorbentes de neutrones en el mismo para absorber los neutrones liberados por el combustible agotado y evitar con ello emisiones indeseables de neutrones de dicho combustible agotado.
