The reactors are more stable as time progresses. By now, the decay heat is greatly reduced and it becomes easier to supply sufficient water for cooling. As far as we know, the containments are holding and the radiation levels have dropped.UC Berkley nuclear expert Peter Hosemann • Suggesting that Fukushima is quickly becoming less of an issue, and more under control. He does warn, however, that radiation may still get into the environment: “We might see some more release of radioactive material, mostly due to the water going through the systems.” Overall, though, this is promising in terms of getting things handled. source (via • follow)
Power lines up in all six Fukushima Daiichi reactors: Which is great sounding news, but they’re not out of the woods yet. There are a number of implications to this, mainly that cooling systems can be turned back on, thus pumping water back into the reactors and preventing a meltdown of the fuel rods. However, the power hasn’t yet been switched on, as engineers fear that the pumps, damaged as they are, could cause an explosion if activated abruptly. That aside, this news is a credit to the bravery of the workers who stayed at the plant. We hope the government gives them truly first-class care once this is over, it’s the only moral thing to do. source
» What happens next: Chief Cabinet Secretary Yukio Edano says that they’ll continue to test food products, and if they find contaminated products, they’ll ban them from the market. Some experts are understandably skeptical. “They should seriously think about restricting any agricultural products in that area,” said Lam Ching-wan of the University of Hong Kong School of Medicine. “It seems that the whole ecosystem could be affected, so they shouldn’t take any chances.” The radiation factor of milk and spinach is important to note, because after Chernobyl, many cancer cases resulted from children who ingested high levels of radiation in milk.
