The Validation referred to in the contract was the plant test in Ferrara. It has nothing to do with Doral, or a year long test. The Validation is the one where Rossi claimed that the government required him to reduce the number of reactors tested to a mere 18 of the 50+ ones in the plant. Rossi made the legal excuse up, and the test was an hour short of the contract period.
Note the Big Frankie’s on the roof of the plant in Ferrara during the Validation.
