According to Tepco, they installed a new purification system into the seaside of reactor3. The system is described as “fibrous adsorbent purification system”, but it only adsorbs Cs-134/137 among all the leaking nuclides. It was installed inside of the silt fence at 14:00 6/17/2013. As a trend, the radioactivity density in seawater of reactor3 is [...]

Posted by Mochizuki on June 16th, 2013
Tepco releases the data about radioactivity density (I-131, Cs-134, Cs-137) of the seawater around Fukushima nuclear plant port on the daily basis. However, they miss the data several times a month. The reason is not announced. They miss the data in the format below, ・No Cs-134 data, no Cs-137 data ・No Cs-134 data but Cs-137 [...]

Posted by Mochizuki on June 10th, 2013
Currently Tepco puts silt fence at 6 locations in Fukushima nuclear plant port in order to stop radioactive material spreading. According to Tepco, they opened one or some of the silt fences for 40 minutes in the morning of 6/4/2013. From their data, the radiation level spiked up by 20 times much outside of the [...]
