Fukushima’s Groundwater Contamination May Be the Worst We’ve Ever Seen in Nuclear History

05/09/2011 Leave a comment

Chief Nuclear Engineer A. Gundersen discusses Fukushima ground water contamination, which could be the worst contamination in the history of the nuclear industry, and discusses a letter from a Japanese government nuclear official and how the Island of Japan was “just plain lucky due to the favorable meteorological conditions during the entire developments of the accident…  We were very lucky even with a large release from 1F3, due to the most severe hydrogen explosion, that could have induced a heavy land contamination.  This resulted from the wind direction toward the sea at the time of the release, although this must have resulted in a wider ocean contamination far from the Fukushima Daiichi.”

Chief Nuclear Engineer Postulates that Fukushima Reactor 3 Explosion was Nuclear

Chief nuclear engineer A. Gundersen postulates that the Fukushima Reactor No. 3 explosion may have been nuclear and not just a hydrogen explosion.  Pieces of nuclear fuel rods were discovered as far away as 2 miles from the plant, which would have happened with a detonation, but unlikely with a deflagration.

Nuclear Engineer Analyzes Current Condition of Fukushima Reactors 1-3, Unit 4 Pool and Monitoring of Fish

A. Gundersen, Chief Nuclear Engineer:  “… What they’re measuring in Unit 2 is not water or steam at all.  It’s hot air, or hot hydrogen.  And that’s a problem.  It tells me that Unit 2 is not being cooled … we should be very concerned that we’re exhausting hot gases out the top of that reactor …

… If we take TEPCO at its word … the iodine deposition on a square meter [Unit 4] was 30,000 MBq.  That’s pushing the numbers at Chernobyl … If we take TEPCO at its word, they had Chernobyl-level releases on the other units which caused the iodine to fall on Unit 4 …

Over the weekend the FDA announced it would not be monitoring fish on the west coast, and I don’t think that’s a good idea … I don’t think we’ll find anything initially, but over the next year as the little fish get eaten by bigger fish get eaten by bigger fish and the plume spreads, we might …”
