METI - Fukushima Dai-ichi reactor readings spreadsheets

Ronan Kelly · Mar 17, 2011

I found this document released on the 18th. The figures in the CAMS row caught my eye. 4.77x10^1 = 47.7 Sv/hour and 7.98x10^1 = 79.8 Sv/hour. These would be massive doses and larger than anything we have seen before. Makoto or anyone, can you throw some light on what this document is about?

Re: Makoto -Help with translation please

It is apparantly reactor unit stats.

The second data row is the coolant height above or below the top of the fuel rods. There's pressures in there - probably reactor pressures, but I'm mighty interested in the radiation readings.

:tiphat: Thanks Makoto,

Those CAMS numbers are not being released on the NISA press releases. I wonder why not? Denise, have you any idea what they mean?

Re: Makoto -Help with translation please

Re: Makoto -Help with translation please

Latest reactor specs document shows Unit 5 water level down, pressure and temperature both up. Also shows a further increase in spent fuel water temperature at Units 5 and 6.
Also includes a radiation reading of 105 Sv/hour at Unit 3.

The outline squiggles were on the document as released.

I am not Denise but an internet search reveals that CAM may stand for Continuous Air Monitoring.

Re: METI - Fukushima Dai-ichi reactor readings spreadsheet - Unit 5: water level dropping, increasing in pressure and temperature

Latest documents (12:00 March 19th) show spent fuel rod pool temperature in Unit 5 at 66.6C, and 66.5C for unit 6. Both up since yesterday.

Pressure in Unit 5 is up again to 1.359MPa from 1.221MPa yesterday.
Water level is up slightly to 1984mm.
Temperature up slightly to 183C.

Pressure in Unit 6 is up from 0.57MPa to 0.825MPa.
Water level has dropped from 2712 to 1620mm
Temperature up from 161.2 to 167.2C

Latest NISA press release 18:30 March 19th http://www.meti.go.jp/press/20110319005/20110319005-1.pdf

Pressure in Unit 5 1.754 MPa ( I'm not 100% certain that this is measuring the same thing as on the spreadsheets), Water level at 1928mm, and spent fuel rod temperature down to 48.1C

Unit 6 has dropped to 0.559 MPa (Same proviso), water level back up to 2590mm, spent fuel pool up slightly at 67C.

Latest update March 20 7:00.

Unit 5: spent fuel temperature: 37.1C, Reactor Pressure down to 1.296 MPa. Water level at 1981mm and Reactor Temperature at 181.3C.

Unit 6: spent fuel temperature: 41.0C, Reactor Pressure 0.716 MPa. Water level 2000mm, Reactor Temperature at 161.8C.

It would appear that restoration of power has stabilized the situation.
