FUKUSHIMA, Oct. 17 — Mochizuki of the Fukushima Diary website has provided a summary of an Oct. 15 report by NHK that reveals “it turned out to be true that water vapor (steam) was splashing (erupting) from underground in June” at Fukushima Daiichi’s No. 1 reactor.
“According to Tepco, it was splashing from underground in June, but now it’s stopped,” the summary continues.
An Oct. 13 measurement in the same location of Reactor No. 1 detected radiation of 4.7 Sv/hr, almost a 20% increase over June’s measurement of 4.0 Sv/hr.
Mochizuki finishes by noting, “It is assumed that melted fuel rods are sinking deep underground, which is called China Syndrome.”

Google Translation of No. 1 to build the house amount of radiation is still high, NHK Oct. 15, 2011:
[...] In Unit 1 of Fukushima Daiichi nuclear power plant, the “melt down” and the other was believed to damage the reactor containment vessel and, in the basement of the reactor building has accumulated a large amount of high concentration of polluted water.
TEPCO reactor building of Unit 1, in order to re-examine the first floor near the southeast side of the steam had come out from underground in the June survey, 13, put a radio-operated robot, radiation looked at the amount.
As a result, in June 4000 was millisievert per hour at most, a survey by the 13th, still has a very high-value measures the amount of radiation 4700 mSv.
Meanwhile, the steam was out in the June survey is that it was not confirmed. 4700 mSv, the Fukushima Daiichi nuclear plant in the building will be second only to the high value of 5000 mSv was measured at the second floor of Unit 1 in August. TEPCO, this high dose, to watch that is water vapor erupted because contaminated water trapped in the basement, future research also are considering the polluted water in the basement.
