New NISA<\/a> and JAIF<\/a> updates. NISA from 06:00 and JAIF from 20:00. Same as usual JAIF number first and NISA after within ().<\/p>\n

 <\/p>\n

Reactor 1:<\/strong>
\nWater level in the core: 1.60 (1.60) meters below the top of fuel assemblies
\nFlow rate of injected water: 141 liter\/minute
\nCore pressure: 603(603) kPa
\nContainment pressure: 285(280) kPa
\nCore temperature(feedwater nozzle):323.3 Celsius
\nCore temperature(bottom head):\u00a0139.4 Celsius
\nDose rate within containment: 36 Sv\/hour<\/p>\n

Reactor 2:<\/strong>
\nWater level in the core: 1.5 (1.5) \u00a0 meters below the top of fuel assemblies
\nFlow rate of injected water: 117 liter\/minute
\nCore pressure: unknown
\nContainment pressure: 100 (110) kPa
\nCore temperature(feedwater nozzle): 153.7 Celsius
\nCore temperature(bottom head):\u00a077.7 Celsius
\nDose rate within containment: \u00a040.4 Sv\/hour
\nSpent fuel pool temperature: \u00a045 Celsius<\/p>\n

Reactor 3:<\/strong>
\nWater level in the core: 2.3 (2.3) \u00a0meters below the top of fuel assemblies
\nFlow rate of injected water: 200 liters\/minute
\nCore pressure: 135 (135) \u00a0kPa
\nContainment pressure: 108.5 (108.5) kPa
\nCore temperature(feedwater nozzle): 61.5 Celsius (obviously error)
\nCore temperature(bottom head):\u00a0120.9 Celsius
\nDose rate within containment: \u00a029.2 Sv\/hour<\/p>\n

Number one is quite hot, otherwise no major change. Running a bit short on time so Kyodo<\/a> has a good summary of the situation and IAEA<\/a>.<\/p>\n

JAIF <\/a>and NISA<\/a> updates. NISA hasn’t released any new information on flow rates, temperatures or containment dose rates. There is no big change in the pressures or water levels of the reactors so I will omit the normal list of parameters I write down. If NISA release temperatures I will include it.<\/p>\n

The Asahi Shimbun<\/a> reports that TEPCO admits there is possible damage to the lower parts of the reactor pressure vessels. TEPCO states that the breaches can not be very large since the pressure in pressure vessels are maintained at a higher level than in the containment structure.<\/p>\n

There seems to be a problem <\/a>again in keeping the number 1 reactor cool. The temperature of the core increased to over 300 degrees celsius again and TEPCO had to increase the flow of water into the core.<\/p>\n
