Q-

As I recall, Units 5 and 6 were shut down for re-fueling and maintenance. So there should be no fuel in their cores. The worry would be with regard to the continued cooling of their spent fuel pools.

As I've vented several times before, the 6 spent fuel pools and the 7th common spent fuel pool are what ups the ante for a nuclear catastrophe at Fukushima-1. The engineers on-site should appreciate that danger. The general public assumes that "spent nuclear fuel" is harmless.

I think that recycling the filtered but still contaminated coolant makes more sense than adding fresh water to the mix. One assumes that the more heavily contaminated water will be filtered again. It would also be nice if their Areva decontamination plant would stay on-line. One wonders what they'll do with the highly radioactive filters, other than dump them into the Pacific.
