While scary, this actually means seawater is getting in to the cores, keeping it from melting down.

Well, maybe.... :blink:

The seawater injection stopped at around 1 a.m. Monday due to a shortage of water left in tanks but resumed for the No. 3 reactor at 3:20 a.m., according to the nuclear safety agency.

The halt of coolant water injection apparently caused rising pressure in the reactor containment vessel and an increase in the radiation levels at the plant, the agency said.

They can't manage to get enough water out of the ocean???

A bit more from the NYT:

The helicopter crew members had landed aboard the U.S.S. Ronald Reagan, a nuclear-powered aircraft carrier whose on-board sensors had indicated that the warship, too, had been exposed to airborne contamination at very low levels. The helicopter crew members were tested individually with hand-held radiation monitors.

The carrier and its strike group were operating about 100 miles northeast of the damaged power plant at the time, but the helicopters had flown closer to assist in relief missions near Sendai, the city that bore much of the brunt of the tsunami after Friday's earthquake.

The Ronald Reagan and other American warships have now sailed to areas where they will not be in the path of radiation carried in the wind.

"As a precautionary measure, U.S.S. Ronald Reagan and other U.S. Seventh Fleet ships conducting disaster-response operations in the area have moved out of the downwind direction from the site to assess the situation and determine what appropriate mitigating actions are necessary," Commander David said.

The worrying thing again is how does the mighty USA military not know that it is sailing into a nuclear fall out area? Relying on the same press releases at the Pentagon these days?

I am sure they had that inconsideration, but came in anyway for humanitarian reasons, and are now moving to a safer spot relative to wind direction. But it didn't say they are completely ceasing aide, just halting for the moment while they assess safety concerns.

Thai gov't approves $6.5 mil. in relief aid for Japan

BANGKOK, March 14, Kyodo News

Thailand's Cabinet on Monday approved the release of 200 million baht (some $6.5 million) in support for relief operations in Japan.

Ongart Klampaiboon, a minister attached to the Prime Minister's Office, told reporters the funds will be used to buy relief materials and to cover the expense of relief missions.

Prime Minister Abhisit Vejjajiva said in his weekly Cabinet meeting Monday that Thailand must do its best to help Japan since the two countries are good friends.

He noted that Japan contributed aid to Thailand during the quake and tsunami disaster here in December 2004.

Thai government spokesman Panitan Watayakorn said relief materials, including rice, blankets and food, will be dispatched to Japan later Monday, while the medical personnel will depart for affected areas early Tuesday.

FWIW, after seeing the Kyodo News report on this, I went searching the U.S. DOD and Navy media web sites, and could find nothing posted there on the subject.... nothing on radiation exposure, nothing on a halt to aide ops by the Ronald Reagan carrier...

If anyone finds anything from the U.S. military on the current status of the Ronald Reagan, please post it here.

Japan Police Site Starts Reporting Quake Damage in English

Tokyo, March 14 (Jiji Press)--Japan's National Police Agency on Monday started releasing on its Web site English-language information about damage resulting from Friday's devastating earthquake in the country, including the number of people killed or missing.

The agency decided on the move because the disaster has been drawing strong interest from abroad, an agency official said.

Japanese-language information has been provided on the site since immediately after the 9.0-magnitude quake jolted northern and eastern Japan and triggered massive tsunami waves on Friday afternoon.

In addition to casualty figures, the English-language page offers prefecture-by-prefecture data on landslides as well as damage to buildings, roads and bridges.

Jfchandler note: Unfortunately, the JiJi Press story above contains no link to the web site in question.

USS Carrier Ronald Reagan Moved After Detecting Radioactive Plume Off Japan

Ship's Crew Was Exposed to Low Level of Radiation

By LUIS MARTINEZ

March 14, 2011 The aircraft carrier USS Ronald Reagan and other US Navy ships in the waters off the quake zone in eastern Japan were repositioned after the detection of a low-level radiation plume from the troubled Fukushima nuclear plant located 100 miles away

According to 7th Fleet Commander and Spokesman Jeff Davis, the ships were moved away from the downwind direction of the plant as a precautionary measure on Sunday.

The carrier is one of seven US Navy ships that were quickly moved to the eastern coast of Japan to assist with relief operations after Friday's earthquake and tsunami.

The ship's crew was exposed to a very low level of radiation.

"The maximum potential radiation dose received by any ship's force personnel aboard the ship when it passed through the area was less than the radiation exposure received from about one month of exposure to natural background radiation from sources such as rocks, soil, and the sun," Davis said.

According to Davis, the radiation was first detected by air particulate detectors aboard three helicopters located 60 miles away from the shoreline.

The helicopters were returning to the carrier from a relief mission to the quake and tsunami ravaged city of Sendai.

Detectors aboard the USS Ronald Reagan also sounded while it was located 100 miles north east of the Fukushima Daiichi Nuclear Power Plant. Low amounts of radioactive materials have been released into the atmosphere as plant officials desperately try to prevent a meltdown of the nuclear cores at two of the plant's reactors.

Davis said the source of the radiation was a radioactive plume emitted by the plant.

After the helicopters landed on the carrier, radioactive contamination was found on the exterior surface of three aircrafts

Following decontamination protocols, the 17 crewmembers aboard and the three helicopters were tested and found to have been exposed to low levels of radiation.

Most of the radiation was found on the crewmembers clothes, but radiation was detected on the skin of one of the crewmembers.

The low level radioactivity from affected personnel was removed by washing with soap and water. Their clothes were also discarded.

They were subsequently surveyed and no further contamination was detected.

A US official said the ship has now moved north, away from where the radiation was detected and the ship's helicopters are not flying until a mitigating strategy to reduce exposure to the ships' crews is determined. Davis stressed that the commitment to the relief mission will continue.

"We remain totally committed to our mission of providing assistance to the people of Japan," he said.

Directy from http://www.c7f.navy....3-march/026.htm

USS BLUE RIDGE, At Sea - The U.S. 7th Fleet has temporarily repositioned its ships and aircraft away from the Fukushima Dai-Ichi Nuclear Power Plant after detecting low level contamination in the air and on its aircraft operating in the area. The source of this airborne radioactivity is a radioactive plume released from the Fukushima Dai-Ichi Nuclear Power Plant.

For perspective, the maximum potential radiation dose received by any ship's force personnel aboard the ship when it passed through the area was less than the radiation exposure received from about one month of exposure to natural background radiation from sources such as rocks, soil, and the sun.

The ship was operating at sea about 100 miles northeast of the power plant at the time.

Using sensitive instruments, precautionary measurements of three helicopter aircrews returning to USS Ronald Reagan after conducting disaster relief missions near Sendai identified low levels of radioactivity on 17 air crew members. The low level radioactivity was easily removed from affected personnel by washing with soap and water. They were subsequently surveyed, and no further contamination was detected.

As a precautionary measure, USS Ronald Reagan and other U.S. 7th Fleet ships conducting disaster response operations in the area have moved out of the downwind direction from the site to assess the situation and determine what appropriate mitigating actions are necessary.

We remain committed to our mission of providing assistance to the people of Japan.

US pulls ships, aircraft from Japan nuke plant

AP - TOKYO -- The U.S. Seventh Fleet said Monday it had moved its ships and aircraft away from a quake-stricken Japanese nuclear power plant after discovering low-level radioactive contamination.

The fleet said that the radiation was from a plume of smoke and steam released from the crippled Fukushima Dai-Ichi Nuclear Power Plant, where there have been two hydrogen explosions since Friday's devastating earthquake and tsunami.

The aircraft carrier USS Ronald Reagan was about 100 miles (160 kilometers) offshore when its instruments detected the radiation. The fleet said the dose of radiation was about the same as one month's normal exposure to natural background radiation in the environment.

OK, so the ABC News report above confirms the earlier Kyodo News report about the suspension of air aid operations from the Ronald Reagan carrier......but you had to go to the very end of the ABC News report to find it...

the ship's helicopters are not flying until a mitigating strategy to reduce exposure to the ships' crews is determined.

If containment vessel is damaged at Fukushima nuclear plant it could be major disaster, but it hasn't happened yet: Japan's ambassador to UK /BBC

It would be nice if the authorities started publishing useful information instead of brain-dead statements like this.
