>George:  Your statements are correct as far as they go; however, you should
note that 10 CFR 70.4 also contains an NRC definition of a sealed source
that is exactly the same as the 10 CFR 30.4 definition except that the words
'special nuclear material' appear in the 70.4 definition instead of the
words 'byproduct material' in the 30.4 definition.  It, therefore, appears
that fuel rods are 'sealed sources' under the NRC's 10 CFR 70.4 definition.
I would be interested to know of the 'other regulations' that you allude to
that regulate/deal with fuel rods from the standpoint of the clarifying why
the NRC apparently feels the regulatory need to declare fuel rods as 'sealed
sources' in 10 CFR 70. REGARDS
