The main problem here is that there's been no public discussion, no public debate, no environmental impact statement, no public hearings, and this material is extremely dangerous. One litre is sufficient to ruin an entire city's water supply, and every one of the 150 shipments will contain 252 litres. Although the packaging is very good, and the industry, of course, expects that everything will be just perfect, why run the risk of transporting this material in liquid form when, if the unforeseeable happens, and it does leak, it will be very damaging to water systems?
You mentioned quite correctly that they're planning to down-blend the highly enriched uranium in order to use it as fuel. They can do the down-blending part right at Chalk River. In fact, they've already done that in Indonesia. Earlier this year, in three months, they down-blended all of their highly enriched uranium liquid waste, and they're not shipping it. They're not shipping it to the United States. This could be done in Canada as well.
The idea of down-blending it for the purpose of using it as reactor fuel is frankly kind of ridiculous, because ordinary fuel is so cheap, comparatively speaking, and this fuel would be extremely expensive. It would also be contaminated with fission products, so it would be more costly than it should be, and it would be dangerous to handle.
