IAEA says radiation levels twice as high as its criterion for evacuation were detected in a village 40 kilometers away from plant. Pressure on Japan to widen evacuation zone.
Radiation 4,385 times higher than the legal standard has been detected in seawater at a location 330 meters south of the plant.

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. The 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. The highest values were found in a relatively small area in the Northwest from the Fukushima Nuclear Power Plant. First assessment indicates that one of the IAEA operational criteria for evacuation is exceeded in Iitate village. We advised the counterpart to carefully access the situation. They indicated that they are already assessing.

Masataka Shimizu, president of Tokyo Electric Power Co, which operates the crisis-hit Fukushima nuclear plant, fell sick March 16 and took some days off from the liaison office between the government and the utility firm, TEPCO officials said Sunday.
While Shimizu was away from the office set up at the firm’s headquarters, he collected information and issued instructions from a different room of the headquarters building to address the troubles at the Fukushima Daiichi nuclear power station hit by the March 11 quake and subsequent tsunami, the officials said. He has already recovered and come back to work at the liaison office, they said.
A TEPCO spokesperson declined to elaborate on his health condition, but said he did not fall over or need to be hooked up to an intravenous drip.
Shimizu has not appeared in public since attending a press conference on March 13, two days after the catastrophe that wreaked havoc on northeastern and eastern Japan.

Chief Cabinet Secretary Yukio Edano says the government and experts are considering whether to cover the reactor buildings with a special material, to stop the spread of radioactive substances.
Tokyo Electric Power Company is struggling to drain off highly radioactive water that has leaked from 3 reactors at the damaged Fukushima Daiichi nuclear power plant.
The Nuclear and Industrial Safety Agency says the levels of radioactive substances detected are low, at one-to-ten percent of those occurring in an operating nuclear reactor.
The agency says the type of radioactive substances found in the water in the tunnel indicates some relation to the contaminated water in the basement of the No.1 reactor turbine building. It says the water in the tunnel will not be released into the sea.

From IAEA briefing for 3/29/11
Fresh water has been continuously injected into the Reactor Pressure Vessels (RPVs) of Units 1, 2 and 3. From today at Unit 1, the pumping of fresh water through the feed-water line will no longer be performed by fire trucks but by electrical pumps with a diesel generator. The switch to the use of such pumps has already been made in Units 2 and 3.
At Unit 1, there has been an increase in temperature at the feed-water nozzle of the RPV from 273.8 °C to 299 °C. The temperature at the bottom of the RPV remained stable at 135 °C.
With the increase in temperature at Unit 1, there has been a corresponding increase in Drywell pressure.
The latest pressure readings reported from NISA for #1 are:

No major progress is reported in the effort to drain radioactive water filling the basements of turbine buildings near 3 reactors in the damaged Fukushima nuclear facility. The delay is hampering work to cool down and stabilize the Daiichi nuclear power plant.h/t peraspera

From the LA Times:
They sleep with just one blanket apiece anywhere there's space — in a conference room, in the hallway, near the bathroom. Because deliveries of supplies are limited, they get by on very little food: Breakfast is packages of high-calorie emergency crackers and a small carton of vegetable juice; dinner consists of a small bag of "magic rice" (just add bottled water) and a can of chicken, mackerel or curry. There is no lunch — handing out a noontime meal would be too complicated in the crowded two-story building

From The Japan Times
Reactor turbine basements flooded with highly radioactive materials kept a desperate effort to stabilize the Fukushima No. 1 power plant at bay Monday, as fresh data showed that nearby seawater was being contaminated further by the leaking facility. Efforts by Tokyo Electric Power Co. to restore the cooling systems for reactors No. 1 through 4, as well as their spent-fuel storage pools, continue to be halted by the highly radioactive water, which is now at lethal levels.

From Kyodo News: URGENT: High-level radiation detected in trench outside Fukushima reactor building
High levels of radiation exceeding 1,000 millisieverts per hour were found in water in a trench outside the No. 2 reactor's turbine building at the troubled nuclear power plant in Fukushima on Sunday afternoon, Tokyo Electric Power Co. said Monday.
Similarly high levels of radioactivity have been found in a pool of water in the basement of the turbine building at the Fukushima Daiichi complex, raising concerns that radioactive substances may have seeped into the environment, including the sea nearby.
