Speaking of conversions – why doesn’t someone in the IRC convert the °C to IF data…for the stupid Americans

The IRC can use this webpage link

http://www.metric-conversions.orgltemperaturelcelsius-to-fahrenheit.htm

(it also provides links for other metric conversions]

Example – I did it for instance in today’s status report – see attached/ and the info pasted below:

[which would make it more useful to the American readers - do'h] wow, how much more useful is that…

STATUS as of 0430 EDT, March 30, 2011 (1730 Japan, March 30)

Unit I – (NRC Priority: 1)

Core Status: Damaged, fuel partially or fully exposed (Source: JAIF, NISA, TEPCO).

The volume of sea water injected to cool the core has left enough salt to fill the lower plenum to the core plate (Source: GEH, US Industry).

Vessel temperatures 138°C [280.4°F] at bottom drain, 309°C [588.2°F] at FW nozzle (Source: NISA-3/29)

138= RPV at 60.5 psig (Source: JAIF 3/29), DW and torus pressure at 26.6 psig (Source: NISA 3/29).

Unit 2 – (NRC Priority: 2)

Core Status: Damaged, fuel partially or fully exposed (Source: JAIF, NISA, TEPCO).

Bottom head temperature 120°C, [248°F] feed water nozzle temperature 153.7°C [308.66° F] (Source: NISA).

RVP pressure -3.9 psig (Source: JAIF 3/29). DW pressure 0 psig (Source: NISA 3/29).

Spent Fuel Pool: Fuel covered, freshwater periodically injected via fuel pool cooling system (Source: TEPCO 3/29),

fuel pool temperature 461°C [114.8° F](Source: NISA 3/29);

Pool may be overflowing based on observations of water in adjacent areas (Source: NRC Team);

white smoke being emitted as of 1830 EDT on March 27 (Source: IAEA 3/28) – confirmed (Source: TEPCO 3/29)

Unit 3 – (NRC Priorit,: 3)

Core Status: Damaged, fuel partially or fully exposed (Source: JAIF, NISA, TEPCO).

Bottom head temperature 121°C [249.8 °F], FW nozzle temperature: 62°C [143.6°F] (Source: NISA 3/29).

RVP pressure -3.7 psig (Source: JAIF 3/29). RPV level -2/3 TAF (Source: IAEA 3/28).

DW pressure 0.97 psig (Source: IAEA 3/28).

Unit 5 – (NRC Priority: 5)

Core Status: In vessel (Source: JAIF, NISA, TEPCO), temperature 35 °C [95°F] (Source: JAIF 3/29)

Just a thought for the IRC’s consideration.
