Do you know offhand if they're doing Pu MOX in CANDU or other compatible reactors? I remember when it was proposed, but didn't catch news of whether they'd gone ahead with it.
The last I heard of the program, which at the time was called the Parallex Project, was that test fuel samples were to be irradiated in the Chalk River test reactor starting near the end of 2000. I don't know if that ever started. Even if it did, there will be a period of time to accumulate the desired flounce, then a fairly extensive program of PIE for the irradiated specimens. The draft EIS addressing the use of MOX in CANDU systems was, as I recall, reasonably positive.
