Radioactive Water Found In Two Reactor Buildings

RedEaredSlider writes "Japan's Nuclear and Industrial Safety Agency said it detected several kinds of radioactive material in the water on the floor of reactor buildings at the Fukushima Daiichi nuclear power plant. The isotopes found in the water were cobalt-76, technetium-99, silver-108, iodine-131, iodine-134, four isotopes of cesium, barium-140 and lanthanum-140. All have half-lives measured in hours or days, with the exception of cesium-137."

      a isotope with a 20K halflife will still be utterly dwarfed in terms of radiation output by something with a halflife of a few decades even if the former has a decay chain 10 isotopes long because it can only add a linear multiplier, not an exponential increase in radiation output.

      Plutonium in perspective.

      As far as widespread release of Plutonium into our environment is concerned, consider this:

      The most important effects of plutonium toxicity by far are those due to nuclear bombs exploded in the atmosphere. Only about 20% of the plutonium in a bomb is consumed, while the rest is vaporized and floats around in the Earth's atmosphere as a fine dust. Over 10,000 pounds of plutonium has been released in that fashion by bomb tests to date, enough to cause about 4,000 deaths worldwide. Note that the quantity already dispersed by bomb tests is more than 10 million times larger than the annual releases allowed by EPA regulations from an all breeder reactor electric power industry.

      Several of the radioactive elements they're finding have half lives of a few hours (I-134 and Ag-108 are less than an hour). For those decay products to be found in significant quantities 2 weeks after shutdown indicates the source of the water has a large concentration of these decay products. This would suggest a leak in the reactor's containment, rather than residual run-off from the water dumping/spraying operations. Reactor 2 sustained a hydrogen explosion inside containment, probably within the torus/suppression pool. So this isn't really a surprise.

      Reactor 3 had no reports of a similar explosion, but they are inferring that containment is breached based on higher than expected radiation measurements. That is the more worrisome one, since it's using a MOX fuel rather than plain uranium. However, they are reporting that reactor 3 isn't losing pressure, so maybe there isn't a leak.

    The best reports on reactor status are at Japan Atomic Industrial Forum, which publishes a status table every day. This is addressed to people in the industry. They just list the facts, without explanation.

    The good news for March 28 is that Unit 3's containment is now listed as "undamaged" instead of "possibly damaged". Unit 2 is listed as "damaged and leakage suspected", and that's now the most worrisome unit.

    There's finally a fresh water supply for cooling. That's a big relief. Sea water cooling in a boil-off situation leaves tons of salt behind, and there was a real worry that the seawater cooling would stop working once too much salt accumulated. Fresh water cooling can continue indefinitely. It's not clear where the water is coming from. Hopefully they have a water line to a reliable source by now, and aren't just bringing in tanker trucks.

    The cores in units 1,2, and 3 still have exposed fuel rods. Until water injection into the core is working again, the reactor can't be brought to cold shutdown. Remember, the reactor vessel is pressurized and contains a mixture of water and steam. Injecting water into a boiler is inherently difficult. Injecting water into a damaged boiler in a ruined structure in a highly radioactive area is very tough.

    The spent fuel pool situation on reactors 3 and 4 is marginally under control. Seawater spray continues, but if they have to keep putting water in, the situation is still bad.

    They're weeks from a stable emergency shutdown.

    That's just the beginning. The situation isn't safe until there are again redundant closed loop cooling systems working. The current cooling hacks dump radioactive water into the ocean.

    Then comes decommissioning. The spent fuel pools have to be cooled for three years or so, and then the fuel rods transferred from the wrecked buildings to dry casks. It will probably be necessary to build another containment building around unit 2, at least. Units 1,2, and 3 are all too damaged to ever de-fuel normally. It's not clear what will be done there. Unit 4 wasn't fueled, but it had a hydrogen explosion while cooling was lost, and will probably never be restarted. Units 5 and 6 can potentially be restarted, but it's doubtful that they will be.

Chernobyl No.1, 2 and 3 reactors were operated for up to 14 years after No.4 blew up and contaminated Europe, and there are 11 other RBMK reactors still in operation elsewhere. The power reactor at the Windscale site was operated for 46 years after the graphite fire in the weapons reactor.
