US nuclear regulators clarify rules for storing spent fuel, fixing old errors

The US Nuclear Regulatory Commission is updating its rules for storing spent nuclear fuel. These changes clarify how to evaluate accident risks and fix minor technical errors in existing storage system approvals.

These are small, technical updates to how spent nuclear fuel is stored. They do not change the fundamental safety requirements or the types of fuel that can be stored. Instead, they make the existing rules clearer and correct some mistakes, which can help streamline future approvals for storage systems.
