WOW WOW Big changes to almost all nisa reports,,, Corrections of “Measuring points of reactor pressure of Unit 2”, “Values of reactor pressure of Units 1 and 3”, and “Location of a monitoring point” of Fukushima Dai-ichi Nuclear Power Station Wrong descriptions have been found in our materials uploaded. We apologize for and correct these as follows. 1. Measuring points of reactor pressure of Unit 2 of Fukushima Dai-ichi NPS The measuring points of reactor pressure of Unit 2 of Fukushima Dai-ichi NPS have been incorrectly written as (A) and (B) since 36th release till 75th release. The correct descriptions are (A) and (D) in materials below. Materials to be corrected Seismic Damage Information (from 36th release to 75th release) Conditions of Fukushima Dai-ichi Nuclear Power Station Unit 1-6 (from 36th release to 75th release) Fukushima Dai-ichi Nuclear Power Station Major Parameters of the Plant (from 36th release to 75th release) 2. Values of reactor pressure of Units 1 and 3 of Fukushima Dai-ichi NPS Tokyo Electric Power Co. Inc. released as attached on this subject. Being accompanied with this release, the values of reactor pressure of Units 1 and 3 of Fukushima Dai-ichi NPS from the 12th release till the 76th release(*) must be corrected in materials below. www.nisa.meti.go.jp

Well sh** this is saying R1 pressures are higher than originally reported!

@NHK Listener I will ask you, since you have been a big defender of the reliability of the data, what do you think now?

@NHK Listener Smells like METI is trying to distance themselves from any implied liability.

I am trying to find further comment : SaeedCNN Saeed Ahmed by ProducerMatthew Japan says situation at the crippled nuclear plant "may turn for the worse"

Japan urges people in 4 more communities near crippled nuke plant to leave within a month. apne.ws

@Sinthia Domina I suspect the errors were from NISA. The changes are very subtle and mostly pressure related. Other than the pressures, seems to be all clarification.

"From 3:59 pm and 4:28 pm on April 10th , we conducted video recording of Unit 1 to 4 reactor buildings from the air by using an unmanned helicopter to check the current status of the buildings." www.tepco.co.jp Any idea if any of these videos have been disclosed to the public?
@bojack54 All were pulled from the Japanese versions. So good question
by NHK Listener 4/11/2011 8:21:56 AM
@bojack54 - The figures at FDP add base atmostpheric pressure, whereas the numbers on the press releases are considered to be on top of base atmospheric pressure.
by Hank Scorpio 4/11/2011 8:22:57 AM
That is the reason why the press releases show negative pressures for #2 and #3.

What do they use as the base (in kPa)? Then I promise to stop nattering about this...
by bojack54 4/11/2011 8:26:09 AM
I think base kPa is just under 100. Somewhere in the range of 80-90, but I'm not sure so don't quote me.
