Two workers missing at plant, crack in reactor building’s roof

Japan nuclear safety agency says two workers are missing after at the stricken Fukushima nuclear reactor after yesterday’s explosion, Reuters reported.

The employees have not yet been identified, but they are believed to have been in the turbine area of the No.4 reactor when a fire broke out, according to Al Jazeera.

An agency official also said there is now a crack in the roof of the reactor building, where workers are desperately trying to prevent the radioactive cores of the plant's reactors from overheating. If the reactor overheats, dangerous radioactive material could be released into the atmosphere.

Go to sleep, Mount Fuji!

After yesterday’s trending Twitter hashtags #edano_nero, which urged overworked government spokesman Yukio Edano to go to sleep, and #kan_okiro, which told Prime Minister Naoto Kan to wake up, Japanese twitter users have riffed on those hashtags to create another clever one: #fujisan_nero, which means “Go to sleep Mount Fuji”.

The epicenter of the 9.0 magnitude quake was very close to the active volcano Mount Fuji, which has not seen activity since the year 1707.

Here’s a picture users have drawn on Twitter to go with #fujisan_nero:

Radiation plume could reach Tokyo

A larger radiation plume from the stricken Fukushima nuclear power plant could reach Tokyo, a U.S. scientists' organization said on Tuesday, Reuters reported.

The Union of Concerned Scientists also said the cooling system at the stricken Fukushima Daiichi plant would be hard to maintain if all workers there were evacuated from the facility.

A crack in the containment vessel could allow radiation to exit the reactor in case of a core meltdown, the scientists warned. They also said the Japanese government should extend the evacuation zone around the troubled plant.

U.S. radiation monitoring equipment to arrive in Japan soon

The Obama administration’s most vocal advocate for nuclear power, U.S. Energy Secretary Steven Chu, says American radiation monitoring equipment will arrive in Japan in two hours, Reuters reported.  

Chu says the Obama administration is still committed to having nuclear power, because the country "needs a diverse supply of energy." Chu also told a House Appropriations subcommittee that America will learn from the crisis in Japan whether safety improvements are needed at U.S. nuclear power plants.  WATCH:

Wall Street expected to tumble after Japan’s stock average plummets

The Dow Jones has opened down 152.88 points, or 1.27 percent, Reuters reported, tracking global equities sharply lower as fears of a nuclear crisis look as if they could send financial markets into a period of turmoil, Reuters reported.

The damage wrought by the earthquake in Japan has disrupted production of automobiles, computer chips and other goods, Neil Irwin reported.  

Japan’s benchmark Nikkei 225 stock average plummeted 10.6 percent to 8,605.15 Tuesday, after declining as much as 14 percent during the day. Tuesday’s precipitous fall followed a 6 percent drop Monday. 

Those declines occurred despite an infusion of yen Monday and Tuesday by the Bank of Japan to try to prop up the nation’s financial system. Analysts estimated that the damage will cost about $180 billion.

Water may be poured through holes in reactor building

Japan reactor operator says workers may pour water through holes in the reactor building into a spent fuel pool, Reuters reported.

Conditions had deteriorated further earlier Tuesday at the troubled Fukushima Daiichi plant when a Japanese nuclear safety official said that the water inside the waste fuel storage pool for a damaged reactor may be boiling.Boiling water could evaporate, exposing the rods, and increasing the likelihood a nuclear meltdown could occur.

Radiation risks for plant workers and Tokyo residents

After fire broke out at a reactor Tuesday, there were fears that emergency crews faced 'very acute' radiation levels. After the rest of the 1,400 employees evacuated the Fukushima Daiichi plant, 50 workers remained in a desperate effort to keep the cores of three stricken reactors cooled.

But radiation levels at the reactor have now become too high for normal work in the control room, Reuters reported.

Outside the plant, radiation levels have risen around Tokyo, with readings up at least nine times higher than normal 15 miles from the capital, Kyodo News reported. Tokyo metropolitan government said it had detected a small amount of radioactive materials in the air, and some residents have fled the capital.  Government spokesman Yukio Edano said the radiation readings had fallen significantly by the evening.

IAEA says Japan has monitored 150 people for radiation levels, and carried out decontamination measures on 23, according to BBC.

Number dead or unaccounted for exceeds 6000

The number of those confirmed dead or who remain unaccounted has exceeded 6,000, a police tally showed Tuesday, Kyodo News reported.

The National Police Agency said 2,475 people were confirmed dead while 3,611 were missing as of noon.

The agency has identified 1,060 bodies so far. 420 of those have been returned to their families.

Thousands of survivors are believed to have taken refuge at places difficult to locate, including 1,300 found stranded on the island of Oshima, Miyagi prefecture, according to local authorities.

Some 7,000 to 8,000 who that have taken shelter at schools have been unable to receive relief goods, they said.

Explosion and fire at plant raise risk of nuclear disaster

Japan’s nuclear emergency became more dire Tuesday after the third explosion in four days hit the troubled Fukushima Daiichi complex, Steven Mufson and Chico Harlan reported. Fire briefly raged in a storage facility for spent fuel rods at a fourth, previously unaffected reactor.

Three hours after the explosion, the radiation level at the plant measured 11,930 micro sieverts per hour. That level is several times the amount a person can safely be exposed to in one year.

But radiation levels shrank dramatically within the next six hours, to 496 micro sieverts per hour. Government spokesman Yukio Edano called it “much higher than the normal level ... but one that causes no harm to human health.”

Tokyo Electric, which over the weekend said it had 1,400 people workingat the complex, evacuated all but 50 workers after the explosion, who remained in a desperate effort to keep the cores of three stricken reactors cooled.


Read more on the explosion and radiation levels here.

Conditions deteriorated further Tuesday when a Japanese nuclear safety official said that the water inside the waste fuel storage pool for a damaged reactor may be boiling.

Boiling water could evaporate, exposing the rods. The fuel rods are encased in safety containers meant to prevent them from resuming nuclear reactions, nuclear officials said, who downplayed the risk of that happening.

But officials acknowledged that there could have been damage to the containers and confirmed that the walls of the storage pool building were damaged.
