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.
--snip--
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.
--snip--
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:
PRESSURE at Gauges A&B IN #1; pressures are reported in MPa.

From NHK
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.

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.

Rules of the Road
Please be kind to kossacks with bandwidth issues. Please do not post images or videos. Again, many thanks for this.
Both the Mothership and the ROVs are for reporting and discussing the developing news. Neither space is for opinions or editorializing on the subject of nuclear energy.
Remember when posting to the thread: STICK TO THE FACTS. Source and link all new information. (This includes insuring authenticity of twitter sources.)
CURRENT TIME IN JAPAN is just a click away for those who want to time/date stamp entries.
Please post news items to the ROV.
*ROV (Remote Operating Vehicle) is a term coined from the Gulf Watchers ongoing coverage of the Deep Water Horizon crisis in the Gulf of Mexico. It is used in place of the term 'child diary' and refers to a diary(s) running concurrently with the Mothership where ongoing discussion and updates to developing news stories occur.
* Please list any diary from the past two days which is not in above list in comments and we will pick it up for posting.
