| Significance and Use | ||||||||||||||||||||||
|
Boron carbide is used as a control material in nuclear reactors. In order to be suitable for this purpose, the material must meet certain criteria for assay, isotopic composition, and impurity content. These methods are designed to show whether or not a given material meets the specifications for these items as described in Specifications C750 and C751. An assay is performed to determine whether the material has the specified boron content. Determination of the isotopic content of the boron is made to establish whether the content is in compliance with the purchaser’s specifications. Impurity content is determined to ensure that the maximum concentration limit of certain impurity elements is not exceeded. |
