Fukushima Updates May 10


Radiation Safety Phillipines blobspot is reporting on a NHK story about rising levels of radiation in reactor #3's spent fuel pool http://falloutphilippines.blogspot.com/

Reactor #3 temperature has also been rising http://www3.nhk.or.jp/daily/english/10_28.html

Quoting NHK http://www3.nhk.or.jp/daily/english/10_30.html
"Tokyo Electric Power Company examined a water sample from the pool on Sunday. The sample contained 140,000 becquerels of radioactive cesium-134 per cubic centimeter, 150,000 becquerels of cesium-137, and 11,000 becquerels of iodine-131.


"None of these substances were detected during an inspection on March 2nd, before the accident triggered by the March 11th disaster.


"TEPCO says these substances may have come from damaged fuel rods in the reactor rather than the damaged spent fuel rods in the pool, because it has detected radioactive iodine, which has a short half-life. Radioactive substances such as iodine are generated during nuclear fission inside a reactor."


"The company says the radioactive substances may have become attached to debris and entered the pool together."


Radiation Safety Phillipines has done the math, calculating that "Each cubic meter of water in the reactor #3 sfp contains 140 billion becquerel of Cs-134, 150 billion becquerel of Cs-137 and 11 billion becquerel of I-131. Very high doses emanating from the water there."


NHK is also reporting that repairs at Unit #1 may have to be slowed because of the high levels of radiation.

Blogger Ex-SKF has translated a statement made by the Nuclear Industrial Safety Agency claiming that the 500 million becquerels released when the doors to Unit #1 were opened is nothing compared to the radiation released into the sea:

"The amount of radioactive materials this time would be 1/300th of the amount released into the ocean when 10,000 tons of water with comparatively low-level contamination was intentionally released; there is no effect on the environment, according to NISA."

Finally, I recommend readers visit Lucas Whitefield Dixson's website. He has a very good summary video up discussing the events and current circumstances. His reporting is very helpful and insightful.
