The Tennessee Department of Environment and Conservation (TDEC) supports the proposed amendments to clarify physical protection regulations regarding large components as radioactive waste. They specifically recommend expanding the exemption to include components from fusion machines, citing similar security risks to those already addressed in the rule.

The commenter supports the NRC's move to formalize exemptions for large components and robust structures into the rule language. However, they suggest refining the criteria to ensure that mobile reactors or components are not exempt, regardless of their weight.
