Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If including non-irradiated fuel elements as a set
Fuel elements (cartridges) have their own provision within heading 8401.
If for research or prototype reactors under 1 MW
Small-scale nuclear reactors for non-commercial use may classify as generators.
If treated as laboratory-scale isotopic separation machinery
Isotopic separation apparatus shifts to other machinery chapters if not reactor-integrated.
