JIJI PRESS, Oct. 16, 2013: NRA Sees TEPCO Steps to Combat Water Leaks Ineffective [...] “Our conclusion is that little effect has been seen” in the TEPCO measures, NRA Commissioner Toyoshi Fuketa said at Tuesday’s meeting of an NRA panel, citing an increase in the levels of radioactive materials in some seawater samples [...] levels of cesium-137 in seawater samples collected between the water intakes for the No. 1 and No. 2 reactors inside the port rose to around 100 becquerels per liter this month from around 10 becquerels between late June and early July, according to TEPCO. “It is reasonable to assume that the total amount of radioactive materials flowing into the sea has risen,” said Masaya Yasui, an emergency response official at the NRA [...]
NHK WORLD, Oct. 15, 2013: TEPCO instructed to look for other possible leaks [...] Japan’s nuclear regulators have instructed the operator of the damaged Fukushima Daiichi nuclear plant to look into the possibility of contaminated water leaking from an unexpected source. [...] data showed hardly any change in radioactive cesium levels in seawater samples taken from the port at the plant in the past 2 months. [...] NRA Commissioner Toyoshi Fuketa said the data raises doubts about TEPCO’s assumptions. [...] Another expert also pointed out that drainage ditches should be inspected for possible water leaks.
Asahi, Oct. 13, 2013: TEPCO measured 320,000 becquerels of tritium [...] per liter from water sampled from an observation well on Oct. 10 located near a storage tank, from which the leakage of 300 tons of highly contaminated water was discovered in August. [...] highly toxic water left after being used to cool the reactors. It marked the first time that water containing 300,000 or more becquerels of tritium per liter was detected from groundwater sampled from the compound of the Fukushima No. 1 plant.
