* So, what's the story here? How can the neutron balance work out? How can he have ended up with 30% of the nickel transmuted into (reasonably stable) copper? The short answer is that this percentage must be way off, or there has been a mis-translation. it is possible that they chose a microgram sample which was visually different - and that it had a wildly distorted ratio, for instance, and following that - an incorrect assumption followed. I see now way for such a large ratio over the entire mass of spent fuel, but even one percent is adequate for testing, and any big shift in copper isotopes will be extremely meaningful. Less so with the nickel. Jones
