TEPCO was going to start removing the fuel rods from the less-damaged reactor building Numnber 4 over the next few days. Today, it was announced that damage to the fuel rod assemblies, some or most of which predated the tsunami and earthquake, this could not be done. There is now uncertainty as to what is…

Fukushima Update

Patrick J. Kiger at National Geographic News has an excellent summary of the current situation at Fukushima Daiichi Nuclear Power Plant. The plant continues to leak radioactive material into the sea, though at a rate much lower than the massive release that happened at the time of the accident. Strontium-90 (Half-life 28.79 years) has increased…

James Hansen on Nuclear Power

James Hansen, the famous climate scientist and author of Storms of my Grandchildren, talks about the possible role of nuclear power in addressing climate change, and in particular, reducing the release of fossil carbon into the atmosphere. I think he is far to pessimistic on the use of solar and wind energy than he needs…

On March 11th, 2011, the Fukushima Daiichi nuclear power plant complex suffered damage from an earthquake and ensuing tsunami that caused multiple nuclear reactor core meltdowns and melt-throughs, explosions, and major releases of radioactive material into the air and the sea. In addition to the reactor meltdowns and melt-throughs spent fuel storage tanks were also…

Wind power is like Ginger Rogers. You know what I mean. It isn’t judged by the same standards as other kinds of electricity generation. Click here to visit an interactive guide to wind power in Minnesota. I’m speaking specifically of the reliability of, or variation in, wind over time. Many people live in places where…

The Fukushima nuclear power plant was opened to journalists for the first time; See below for numerous links to related stories. There appears to be very high levels of radiation at Fukushima plant reactor #3, and at either reactors 1 and 3, or both, nuclear fission may have been occurring in the melted down remains.…

One of the interesting items we have this week is a study by Greenpeace in which various organisms from the sea near Fukushima were sampled for radioactive isotopes. Let’s take a closer look. The data in the table provided (see the first item in Ana’s feed for the link) show the amount of radiation (radioactive…
