I think it is likely that ZEN could already have done the analytical tests on Albany material to see if it meets the nuclear standard, basically low boron. This is very simple to do and I see no need for them to trumpet these results as others are doing. The reason is that before anyone will seriously consider your graphite for nuclear use it has to be tested in a reactor and you are likely looking at supplying several tons of purified material for use during an 18 month test. There are not very many reactors currently being built from what I can tell except in China and likely they will use synthetic graphite for the time being to guarantee supply and reduce risk.

Personally while this is a sexy application, likely needs very high quality material and could be important in the future, I don't see it as the biggest potenial market by a long shot at the moment.
