It's not a government subsidy in that these reactors have been sold for less than their cost of production. On the way it has worked for AECL in the past, it has incurred costs and been reimbursed by the buyers--utilities or other purchasers. Sometimes export financing was involved, but my understanding is that the projects covered their costs overall.
So AECL's history of losses is not attributable to individual losses on these projects as much as contributions to overhead, the laboratories, and so forth.
