I understand that but are there any indications that DOE is on the table with Positron? I would be happy if that happens. The only LOI is with JDI. I will guess any real revenue from JDI is atleast an year away. I will discount Sr sale that Positron provides for any validation exercise with JDI. Assuming Ruby-fill gets approved by June 2013, they will have to find a decent market to make a consistent revenue stream. I haven't seen any news of Positron talking with DOE. I know they are pursuing for handling sr from one of their filing. But no status on this yet.
