The big Frankies (isn't that a typicall Italian name..?) were designed and manufactured by a third party certainly not Rossi.
May be you should tell us, why this third party is not willing to do a new test!
The reactor bodies are useless without the fuel and the control box and the "special Rossi know how".
And "Frankie" isn't Italien, it is Italo-American for Francesco, IMHO
