JAPAN: SECOND BLAST AT FUKUSHIMA—BLAST IN REACTOR No3—-REACTOR No2 LOST ITS COOLING CAPACITY AND HAD EXPOSED FUEL RODS—TEPCO SAIS PARTIAL MELTDOWN IN REACTOR 1 HAS BEGUN–News about the general situation in Japan.

U P D A T E : THIRD BLAST WAS HEARD IN FUKUSHIMA JUST MINUTES AGO, I MIGHT HAVE CAPTIONED THE THIRD BLAST UNAWARE WHAT IT WAS. SCROLL DOWN TO SEE THE PHOTOS AND A “WEIRD” SMOKE AS I HAD DESCRIBED IT.

INCOMING NEWS!!!: THE THIRD BLAST HAS CONFIRMED AND IT HAPPENED AT REACTOR No2 —

From Yahoo News

By ERIC TALMADGE and MARI YAMAGUCHI, Associated Press – 14 mins agoThe blast at Dai-ichi Unit 2 followed two hydrogen explosions at the plant — the latest on Monday — as authorities struggle to prevent the catastrophic release of radiation in the area devastated by a tsunami.
The latest explosion was heard at 6:10 a.m. Tuesday (2110 GMT Monday), a spokesman for the Nuclear Safety Agency said at a news conference. The plant’s owner, Tokyo Electric Power Co., said the explosion occurred near the suppression pool in the reactor’s containment vessel. The pool was later found to have a defect.
International scientists have said there are serious dangers but not at the level of the 1986 blast in Chernobyl.
Japanese authorities said there have been no large-scale radiation releases, but have detected temporary elevations in levels, and have evacuated tens of thousands of people from around affected reactors. Prevailing winds were pointing out to sea, and U.S. ships assisting tsunami recovery moved further way to avoid potential danger.

 

 

TOKYO officially admitted that they can’t control the situation in the nuclear station of Fukushima. They asked for IAEA (International Atomic Energy Agency) to help.

NUCLEAR STATION:

Blast in No3 reactor occurred this Monday in Fukushima Daiichi nuclear station.

No2 lost all its cooling capacity and a partial meltdown might already be underway.

It had already lost its electricity powered cooling system when the earthquake hit  but now it lost it’s third safety backup cooling system (the other two safety systems failed as well) that was needed to cool the core down.

MONDAYS BLAST

They started injecting seawater and boron in No2 but it got evaporated and had its fuel rods exposed at least twice for some significant period of time (two hours), so the fuel rods may have already started melting inside the reactor and that could reach the zirconium that surrounds the fuel rods which would lead to a complete meltdown. They have opened vents in the containment vessel, which could release small amounts of radiation… Radioactive materials have been found in the area in small numbers. The normal temperature that a reactor needs to have is 270 degrees Celsius. But with exposed fuel rods and no cooling system, the temperature may rise to 2,000 Celsius! After that, the super-duper-hot core will penetrate the vessel and …hit the floor. Imagine a hot coal burning a plastic grocery bag.

Fuel Rods: Geometrical form in which nuclear fuel surrounded by cladding material is inserted into a reactor. Several fuel rods are normally compiled into a fuel element. In the Krümmel Nuclear Power Plant with a boiling water reactor, 72 fuel rods form a fuel element, in the pressurized water reactor of the Emsland Nuclear Power Plant a fuel element contains 300 fuel rods.

(while I was checking out the camera too, I noticed a smoke coming out although the two blasts have already happened. Maybe it's the steam they release to low the pressure in the vessel? I had taken one snapshots in one hour difference.Notice the second pic and the smoke.)

Japanese agency: Explosion heard at nuclear plant

– 22 mins ago

TOKYO – Japan’s nuclear safety agency says an explosion has been heard at Unit 2 of the Fukushima Dai-ichi nuclear plant. An agency spokesman speaking Tuesday on national television said the explosion was heard at 6:10 a.m. (2110 GMT).

No other details were immediately announced.

The troubles at the Fukushima Dai-ichi complex began when Friday’s massive earthquake and tsunami in Japan’s northeast knocked out power, crippling cooling systems needed to keep nuclear fuel from melting down.

A typical nuclear plant has about as much radioactive material as about 1,000 bombs that were dropped on Hiroshima in Japan during World War II, said Ira Helfand, a board member with Physicians for Social Responsibility.

*     *     *     *     *     *     *     *     *     *     *     *

Vladivostok, Russia: Scientists monitoring every hour the levels of any possible radiation coming from Japan. But there was no leak or irregularities that they could spot (yet).

The U.S. Seventh Fleet said that some of its personnel, who are stationed 100 miles (160 kilometres) offshore from the Fukushima Daiichi plant, had come into contact with radioactive contamination. The airborne radioactivity prompted the fleet to reposition its ships and aircraft.

Using sensitive instruments, precautionary measurements were conducted on three helicopter aircrews returning to USS Ronald Reagan after conducting disaster relief missions near Sendai. Those measurements 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, and later tests detected no further contamination.

Japanese scientists reassure people that the radiation that has leaked (because of the blasts and the method of taking the pressure out of the reactors to calm them down and avoid a meltdown, which released a small cloud/steam of radioactive elements) are in very low levels, which equals to the normal radiation a person experiences in one month of normal everyday living.

ELECTRICITY BLACKOUTS:

Power is cut very often sometimes up to 3 hours at a time. At the iconic crosswalk in front of Tokyo’s Shibuya train station – usually a riot of lights and noise – massive video screens were turned off, and pedestrians moved in silence. Many stores and company buildings have reduced their hours. Trains ran on limited schedules.

People are buying generators and the companies that sell generators have a hard time to catch up.

EARTHQUAKE/TSUNAMI:

There is a 40 per cent of 5 or more magnitude aftershocks are expected to happen in the next three days. Major aftershocks like that, could cause new tsunamis.

*     *     *     *     *     *     *     *     *     *     *     *

Japanese are trying to fix the roads but it’s a hard job because of the constant aftershocks.

*     *     *     *     *     *     *     *     *     *     *     *

PEOPLE:

People are filling up their cars with gas just in case there will be a sudden running out of gas. Authorities ask people to stop buying unnecessary products. There were few customers that complain about the limit of the amount of the products they can buy. Food supplies in supermarkets are running out and the owners do not know when the next supplies will come. The supermarkets even charge their products in much lower prices, so they can help a little their fellow compatriots in these hard times.

*     *     *     *     *     *     *     *     *     *     *     *

The official death toll from the earthquake and the tsunami is up to 1,900

10.000 people are missing in just one prefecture (more than half of the population of that prefecture)

*     *     *     *     *     *     *     *     *     *     *     *

Bodies found in hundreds every day close to the shores where the tsunami hit

*     *     *     *     *     *     *     *     *     *     *     *

Half a million people live in evacuation facilities. Shelters are running out of water, food, heat or fuel.

WORLD FOR JAPAN:

30 countries are to assist Japan with rescue teams

*     *     *     *     *     *     *     *     *     *     *     *

A French team is expected to arrive in Japan to treat and decontaminate people that might have been exposed to any level of radiation.

*     *     *     *     *     *     *     *     *     *     *     *

USA “takes a break” over building 20 new nuclear stations in USA after what happened in Japan. Germany and France think the same.

*     *     *     *     *     *     *     *     *     *     *     *

Independent Sen. Joe Lieberman on Sunday called for a temporary moratorium on the construction of nuclear power plants in the U.S. in the aftermath of Japan’s devastating earthquake and tsunami, which damaged two reactors at a nuclear facility in the country’s northeast.

“This is obviously a significant setback for the so-called nuclear renaissance,” said Peter Bradford, a former commissioner of the U.S. Nuclear Regulatory Commission. “And significant radiation releases… cannot be good things for an industry that’s looking for votes in the Congress and in the state legislatures,” Bradford added.
