Update On Power Outage At Fukushima Daiichi

TEPCO has released a document confirming a few things and with some additional information.

These facilities are still out:
Units 1, 3 and 4 spent fuel pool cooling
Common pool cooling
Gas handling at unit 3
Kurion water filtration system
Unit 2 is not mentioned. They reference primary and secondary pool cooling systems for units 3 and 4 as both being out and only the secondary for unit 1. TEPCO goes on to give outage temperature increase estimates for units 1, 3, 4 and the common pool. TEPCO’s estimates for heat up increase seem plausible, our estimate for unit 4 spent fuel pool heat up rate was .19℃/h

Unit 1:
Temp increase rate: 0.076℃/h
Temp as of 3.18 afternoon: 16℃

Unit 3:
Temp increase rate: 0.146℃/h
Temp as of 3.18 afternoon: 13.7℃

Unit 4:
Temp increase rate: 0.368℃/h
Temp as of 3.18 afternoon: 25℃

Common Pool:
Temp increase rate: 0.226℃/h
Temp as of 3.18 afternoon: 25.2℃
