Worker exposure to high levels of nuclera radiation and the distribution of radioactive materials about the landscape and in possibly unexpected places are the stories of the week at Fukushima. Also, officials are wondering, how have the potential effects of a tsunami at Fukushima (and, apparently, it is possible to have a tsunami here) changed given that the reactor is now a series of large pools of highly contaminated water?
The power being supplied to cooling pumps at Units 1,2 and 3 had been switched back to emergency generators because the connections established several days ago need to be reworked. Subsequently, the supply was switched back to the off-site grid. Mysterious white smoke has stopped coming out of Reactor Unit 4 (about five or six days ago) but the smoke continues to be emitted from units 2 and 3. Water is still being pumped into reactors, and nitrogen is still begin injected to avoid a hydrogen explosion. Pressure and temperature readings at the reactors are still not what they should be for a cold shutdown.
Few people know it, but Fukushima Daiichi Power Plant once starred in a movie about how to build a nuclear reactor:
