Fukushima Updates 10/17

Today's Fukushima Updates begins with a detailed explanation of Friday's "no-melt-through" claim with respect to F. Daiichi unit #1, followed by other important updates.
 
Commentary - No “Melt-throughs” at Fukushima Daiichi? – a Detailed Explanation - Objections to Friday's claim of no "melt-through" of the unit #1 RPV at F. Daichi are addressed. If the melted fuel material (corium) did burn through the RPV bottom head, the data from inside the primary containment would be very, very different. This detailed explication demonstrates why there has probably been no melt-through with Fukushima Daiichi unit #1 RPV.
Updates - A team of American experts have concluded that F. Daiichi unit #4 spent fuel pool was never really a danger... High-resolution pictures from inside F. Daiichi SFP #3 show no damage to the stored fuel bundles... Tepco reports that a water leak was discovered on the first floor of the F. Daiichi unit #2 turbine building on Monday... Seismic investigation of the geologic anomaly under the currently-operating Oi NPS will begin on November 2nd... The Seismological Society of Japan has announced they will avoid use of the term “prediction” when making future earthquake projections... New Science and Education Minister, Ms. Makiko Tanaka, has questioned Tokyo’s recent no-nukes policy.
