Update 12:00(CET)\/10:00(UTC)\/19:00(JST)<\/strong><\/p>\n

New JAIF<\/a> update for today, I will compare it with the NISA<\/a> update from yesterday.<\/p>\n

Reactor 1:<\/strong>
\nWater level in the core: 1.65 (1.60) meters below the top of fuel assemblies
\nFlow rate of injected water: 133 liter\/minute
\nCore pressure: 612(592) kPa
\nContainment pressure: 210(230) kPa
\nCore temperature(feedwater nozzle): 251.2 (270.1) Celsius
\nCore temperature(bottom head):\u00a0130.2 Celsius
\nDose rate within containment: 37.7 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: 133 liter\/minute
\nCore pressure: unknown
\nContainment pressure: 110 (100) kPa
\nCore temperature(feedwater nozzle): 174.3 Celsius
\nCore temperature(bottom head):\u00a0Unknown
\nDose rate within containment: \u00a039.6 Sv\/hour
\nSpent fuel pool temperature: \u00a048 Celsius<\/p>\n

Reactor 3:<\/strong>
\nWater level in the core: 2.3 (2.25) \u00a0meters below the top of fuel assemblies
\nFlow rate of injected water: 116 liters\/minute
\nCore pressure: 121 (119) \u00a0kPa
\nContainment pressure: 173 (164) kPa
\nCore temperature(feedwater nozzle): 75.3 Celsius (under review)
\nCore temperature(bottom head):\u00a0116.0 Celsius
\nDose rate within containment: \u00a026.8 Sv\/hour
\nStatus with the reactors are pretty much unchanged. Work is\u00a0proceeding\u00a0with pumping away junk water from turbine halls so one can repair the coolant pumps. Work is slow however due to lack of any place to put the radioactive water.<\/p>\n

IAEA released a new estimate<\/a> on ground fallout yesterday and its not pleasant reading. Here is a quote:<\/p>\n

Based on measurements of I-131 and Cs-137 in soil, sampled from 18 to 26 March in 9 municipalities at distances of 25 to 58 km from the Fukushima Nuclear Power Plant, the total deposition of iodine-131 and cesium-137 has been calculated. The results indicate a pronounced spatial variability of the total deposition of iodine-131 and cesium-137.\u00a0The average total deposition determined at these locations for iodine-131 range from 0.2 to 25 Megabecquerel per square metre and for cesium-137 from 0.02-3.7 Megabecquerel per square metre.<\/em><\/p>\n

This is Chernobyl level<\/a> ground deposits of Cs-137 around the plant and indicates one might have to expand the evacuation zone around Fukushima. The basis of the IAEA estimate is from the dust samples published by MEXT<\/a>.<\/p>\n
