Strategic Significance
The ALLOBOR-5 alloy is being developed for the inner basket of spent nuclear fuel (SNF) containers as part of the CLTDS-SNF-BA project. This boraluminum material is designed to ensure storage integrity for over 100 years, offering significant advantages over existing technologies.
This certification represents a critical milestone in the Czech-Ukrainian collaboration to develop indigenous SNF container technology, reducing dependence on foreign suppliers and strengthening European energy security.
