Table of Contents
The Nuclear Regulatory Commission is proposing changes to the safety and storage guidelines for a specific type of dry cask used to hold spent nuclear fuel. These casks, made by NAC International, Inc., are called MAGNASTOR systems. The agency is updating Certificate of Compliance No. 1031 with Amendments 16 and 17, along with revisions to earlier amendments.
Why it matters: This is primarily an administrative update to technical standards for existing equipment. It ensures that the safety criteria for these specific storage casks remain current and compliant with federal law. For nuclear plant operators using these casks, it maintains the ability to store spent fuel without navigating new, separate licensing hurdles for each site.
