The Wall Street Journal just announced that Tokyo Electric Power (TEPCO) is postponing its shutdown efforts at Fukushima Daiichi:
Officials postponed a plan to ramp up efforts to cool nuclear fuel at the stricken Fukushima Daiichi nuclear complex amid concerns that the use of thousands of additional metric tons of water could result in dangerous leaks.
Reason for the postponement? Fears of leaks and explosions:
The trial run saw a more-than-anticipated drop in the temperature and the pressure inside the plant’s No. 1 reactor, raising the possibility that air from outside could enter and spark an explosion when oxygen hits the hydrogen inside the reactor. Similar explosions in the first week of the crisis exacerbated damage and radiation at the plant.
Officials also had lingering concerns about possible leakage in the containment vessel, said Hidehiko Nishiyama, spokesman of the government’s Nuclear and Industrial Safety Agency. No visible leakage has been found in the containment vessel so far, however.
Don’t believe anyone who tells you that the crisis is over….
