      Updated with readings as of:        03/24/2011          
      Please note: The water levels are measured from the top of the assemblies down to where the water is. These assemblies are exposed.                  
      a "-" sign will be in front of the number as long as they are reporting that water is below the assemblies.                  
      Pressure readings are MPa, Temperature reading are Celcius, Water level reading are in milimeters (mm)

      Spent Fuel Pool temps had been decreasing in #5. Power supply to Unit 5 was switched from the Emergency Diesel
      Generator to external power supply. (11:36 March 21st)
      The pumps for Residual Heat Removal (RHR) was automatically stopped when the power supply was switched from the temporary to the permanent. (17:24 March 23rd). Temps have risen somewhat.

      Power supply to Unit 6 was switched from the Emergency Diesel  Generator to external power supply. (19:17 March 22nd). Temps have been steadily decreasing and this spent fuel pool is considered stable.
      Reactor 6 SFP Temp: 23.5

       It was confirmed that the water level of Spent Fuel Pool was maintained full after 06:00 March 18th.
      Water spray over the Common Spent Fuel Pool was started (From 10:37 till 15:30 March 21st)
      As of 09:00 March 19th, the water temperature in the pool was 57℃.
      As of 16:30 March 21st, water temperature of the pool was around 61℃.
      As of 13:15 March 23rd, water temperature of the pool was around  57℃

      All 3/24 data based on current update from GRS (German site) found here

      We have historical data stored by reactor/by date in the Daiichi Database Diary for 3/17 - 3/21. In light of that, I'm just going to cover 3/22 - 3/25. These 3/25 #'s are based on NISA's 3rd release for 3/25 at 18:00 found in a nice graphic here

      Please note: This info. is NISA's second release for 3/29 stating the time as 15:00 though the readings are for 12:00. There is usually a release of data readings for 14:00. These do not appear to have been released.

      Fukushima - Daiichi                  
      Updated with readings as of:        03/29/2011          
      Please note: The water levels are measured from the top of the assemblies down to where the water is. These assemblies are exposed.                  
      a "-" sign will be in front of the number as long as they are reporting that water is below the assemblies.  
      Please note: the fuel rods are approximately 4 meters long (4,000mm). So if a reading is -2,000, 1/2 the rods are exposed.              
      Pressure readings are MPa, Temperature reading are Celcius, Water level reading are in milimeters (mm)

      Per NISA's summary report
      http://www.nisa.meti.go.jp/....
      Under section 3, Condition of each unit, the following is noted for EACH reactor building 1 through 4.
      ・ White smoke was confirmed to generate continuously Unit 1 (As of 06:30 March 29th)
      Unit 2 (As of 06:30 March 29th)
      Unit 3 (As of 06:30 March 29th)
      Unit 4 (As of 06:00 March 29th)
      TEPCO's webcam is currently off so there is no way to confirm if the steam is still being generated. This notation regarding white smoke being continuously generated has appeared for several consecutive days.
