I done this a long time ago

I think so;
Left instrument scale 0 - 0.5 (current reading 0.1)
Right Instrument scale 0 - 0.4 (current reading 0.2)
Center instrument scale 0 - 0.1 (current reading 0.1)
All scales in MPa

I see now, Hight side pressure - 0,1 MPa, low side pressure 0,2 MPa, and differential pressure - 0,1 MPa
So reactor presure is 0,2 MPa - 0,18 MPA = 0,02 MPa
equation from here: http://www.tepco.co.jp/en/nu/fukushi...10602_02-e.pdf
So we should now add 0,1013 to result
so 0,1013 + 0,02 = 0,1213 so it is litle bigger than atmospheric pressure ?

weee my computations were correct, look on tepco data summary 6/4 at 12:00
http://www.tepco.co.jp/nu/fukushima-..._summary-j.pdf
0,025MPa + 0,1013=0,1263
So where all nitrogen go ?



Ps. also water level in unit 1 sfp hit low record - only 1m, if they will not inject water fuel will be exposed in less than 24 h
REACTOR 1 RPV IS AT ATMOSPHERIC PRESSURE !
