SOMA, Japan

— Radiation is spewing from damaged reactors at a crippled nuclear power plant in tsunami-ravaged northeastern Japan in a dramatic escalation of the 4-day-old catastrophe. The prime minister has warned residents to stay inside or risk getting radiation sickness. Radiation is spewing from damaged reactors at a crippled nuclear power plant in tsunami-ravaged northeastern Japan in a dramatic escalation of the 4-day-old catastrophe. The prime minister has warned residents to stay inside or risk getting radiation sickness.

Chief Cabinet Secretary Yukio Edano said Tuesday that a fourth reactor at the Fukushima Dai-ichi complex was on fire and that more radiation was released.
Prime Minister Naoto Kan warned that there are dangers of more leaks and told people living within 19 miles (30 kilometers) of the Fukushima Dai-ichi complex stay indoors.

A third explosion in four days rocked the earthquake-damaged plant early Tuesday.

Two sources told NBC News' Robert Bazell that the blast breached the containment
structure and that radiation had leaked out.

The agency said the explosion may have damaged the reactor's suppression chamber, a water-filled tube at the bottom of the container that surrounds the nuclear core, said agency spokesman, Shinji Kinjo. He said that chamber is part of the container wall.

The suppression chamber is used to turn steam back into water to cool the reactor and also plays a role in removing radioactive particles from the steam.

Radiation levels measured at the front gate of the Dai-ichi plant spiked following Tuesday's explosion, Kinjo said.

Detectors showed 11,900 microsieverts of radiation three hours after the blast, up from just 73 microsieverts beforehand, Kinjo said. He said there was no immediate health risk because the higher measurement was less radiation that a person receives from an X-ray. He said experts would worry about health risks if levels exceed 100,000 microsieverts.
The blast at Dai-ichi Unit 2 followed two hydrogen explosions at the plant — the latest on Monday — as authorities struggled to prevent the catastrophic release of radiation in the area devastated by a tsunami.

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

The latest explosion was heard at 6:10 a.m. local time on Tuesday, 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.

Radiation levels in the air surrounding the plant had risen four-fold after a fresh explosion at the site on Tuesday, the plant operator said.

The radiation reading at 08:31am local time (2331 GMT) climbed to 8,217 microsieverts an hour from 1,941 about 40 minutes earlier, Tokyo Electric Power Co said.
The company said some employees of the power plant were temporarily evacuated following Tuesday morning's blast.

The accidents — injuring 15 workers and military personnel and exposing up to 190 people to elevated radiation — have compounded the immense challenges faced by the Tokyo government as it struggles to help hundreds of thousands of people affected by twin disasters that flattened entire communities and may have left more than 10,000 dead.

The latest explosion came as Japanese engineers pumped seawater into Unit 2 of the Fukushima Dai-ichi plant after coolant water levels there dropped, exposing uranium fuel rods.

The water drop left the rods no longer completely covered in coolant, thus increasing the risk of a radiation leak and the potential for a meltdown at the Unit 2 reactor, Tokyo Electric Power Co. said.

3 reactors 'likely' melting
Workers managed to raise water levels after the second drop Monday night, but they began falling for a third time, according to Naoki Kumagai, an official with Japan's Nuclear and Industrial Agency.

It now seems that the nuclear fuel rods inside all three functioning reactors at the Fukushima Dai-ichi
complex are melting, a senior government official said.

Advertise | AdChoices"Although we cannot directly check it, it's highly likely happening," Edano said.

Some experts would consider melting fuel rods a partial meltdown. Others, though, reserve that term for times when nuclear fuel melts through a reactor's innermost chamber but not through the outer containment shell.

Officials held out the possibility that, too, may be happening. "It's impossible to say whether there has or has not been damage" to the vessels, Kumagai said.

If a complete reactor meltdown — where the uranium core melts through the outer containment shell — were to occur, a wave of radiation would be released, resulting in major, widespread health problems.

Also unknown was the status of any nuclear waste that might be stored at the site, and whether the pools housing used fuel were still being cooled to prevent a radiation release.

The cabinet secretary's comments followed a hydrogen explosion at Unit 3 on Monday that injured 11 workers and was heard 25 miles away. A similar explosion happened at Unit 1 on Saturday.

Japanese Prime Minister Naoto Kan later said the government was setting up a joint response headquarters with TEPCO to better manage the crisis.
Of all these troubles, the drop in water levels at Unit 2 had officials the most worried.

"Units 1 and 3 are at least somewhat stabilized for the time being," said Nuclear and Industrial Agency official Ryohei Shiomi. "Unit 2 now requires all our effort and attention."

The blast occurred as authorities tried to cool the reactor with seawater.

"It's like a horror movie," said 49-year-old Kyoko Nambu as she stood on a hillside overlooking her ruined hometown of Soma, about 25 miles from the plant. "Our house is gone and now they are telling us to stay indoors.
"We can see the damage to our houses, but radiation? ... We have no idea what is happening. I am so scared."Authorities said operators knew an explosion was a possibility as they struggled to reduce pressure inside the reactor containment vessel, but apparently felt they had no choice if they wanted to avoid a complete meltdown. In the end, the hydrogen in the released steam mixed with oxygen in the atmosphere and set off the blast.

In some ways, the explosion at Unit 3 was not as dire as it might seem.

The blast actually lessened pressure building inside the troubled reactor, and officials said the all-important containment shell — thick concrete armor around the reactor — had not been damaged. In addition, officials said radiation levels remained within legal limits, though anyone left within 12 miles of the scene was ordered to remain indoors.

"We have no evidence of harmful radiation exposure" from Monday's blast, Deputy Cabinet Secretary Noriyuki Shikata told reporters.

On Saturday, a similar explosion took place at the plant's Unit 1, injuring four workers and causing mass
evacuations. A Japanese official said 22 people had been confirmed to have suffered radiation contamination and up to 190 may have been exposed. Workers in protective clothing used hand-held scanners to check people arriving at evacuation centers.

While four Japanese nuclear complexes were damaged in the wake of Friday's twin disasters, the Dai-ichi complex, which sits just off the Pacific coast and was badly hammered by the tsunami, has been the focus of most of the worries over Japan's deepening nuclear crisis. All three of the operational reactors at the complex now have faced severe troubles.
The length of time since the nuclear crisis began could indicate that the chemical reactions inside the reactors were not moving quickly toward a complete meltdown.

"We're now into the fourth day. Whatever is happening in that core is taking a long time to unfold," said Mark Hibbs, a senior associate at the nuclear policy program for the Carnegie Endowment for International Peace. "They've succeeded in prolonging the timeline of the accident sequence."

He noted, though, that Japanese officials appeared unable to figure out what was going on deep inside the reactors. In part, that was probably because of the damage done to the facility by the tsunami.

"The real question mark is what's going on inside the core," he said.

sounds like maybe 5 reactors are now in trouble.

How much radiation is dangerous?

Radiation is measured using the unit sievert, which quantifies the amount of radiation absorbed by human tissues. One sievert is 1,000 millisieverts (mSv). One millisievert is 1,000 microsieverts.

The average person in the United States is exposed to about 6.2 millisieverts a year, mostly from background radiation and medical tests.

Some facts about radiation exposure:

•A person would need to be exposed to at least 100 mSv a year to have an increase in cancer risk. Exposure to 1,000 mSv (1 sievert) over a year would probably cause a fatal cancer many years later in five out of every 100 people who receive that much radiation.

•A total body CT scan exposes a person to about 10 mSv.
•A mammogram exposes a woman to about 0.7 mSv.
•CT colonography is about 5 to 8 mSv.
•A CT heart scan is about 12 mSv.
•A typical chest X-ray involves exposure of about 0.02 mSv
•A dental X-ray can be 0.01 mSv.
•Coast-to-coast airplane flight exposes a person to about .03 mSv. Airline crews flying the New York-Tokyo polar route are exposed to 9 mSv a year.

Here's some food for thought.

ABWRs are at work here in the US.

Near fault lines.

"Of the 110 active nuclear power reactors in the United States, thirty-five are boiling-water reactors (BWR)."
NRG, Toshiba to promote ABWRs | Homeland Security News Wire

More good news.

If there is a breach, and the fallout from this hits the Jet Stream, it will hit the west coast of the US in a few days.

Can't cover up all the crops and animals. Or the water supply.

And a little more news. Old, but news never the less.

GE Hitachi Nuclear Energy?s ABWR Renewal Application Formally Accepted by the NRC | Business Wire

They got that done just in time.


Because....

"In 1997, GEH's ABWR became the first Generation III model certified for U.S. construction, but more than 13 years later, most utilities are still deciding whether to begin building new nuclear power plants. With a single nuclear power plant project representing an investment of billions of dollars, NRC-certification status is among the key factors a utility considers in selecting a reactor model."

that paragraph pretty much defines exactly my rage at listening to people discuss such things. i couldn't have said it so eloquently, because i would most likely have been spewing obscenities and insults along with my nuclear physics diatribe.

about shooting shit into space, ya itll be expensive now... thats why i said not untill we discover a cheap way to break atmosphere.

and as an equivalent to polluting our own earth... hardly. Yes the same concept but its on such a bigger scale that it is completely different. It would take thousands and thousands and thousand of years at a minimum for whatever waste to hit anything if aimed correctly, even if aimed shittily it would still take that long.
Seems doubtfull that we will be around that long anyway...

it is BY FAR the best possible way that we could "dispose" of waste that we know of and imo should be a major goal we work on...the ability to break atmosphere cheaply.


nothing is ever fully "disposed" of anyway, its just changed. Some things we are unable to change into harmless things still...

Might as well get them the fuck off the planet that we need.

id love to hear why you think its a bad idea, because it seems the most logical thing to do atm to me.
What other options do we have?

can you imagine if we could stop polluting our earth with wastes? The change would be DRASTIC. .. we still have yet to even experience the long term effects of most pollutants as they havent been around that long. Shits gonna be FUCKED in less we do something.

eliminating waste would free up many people to put there environmentally friendly brains elsewhere for the good of mankind.

so yeah shooting shit into space isnt perfect, but we arent even close to a perfect solution if its even possible at all, and while not perfect.. sending waste into space is a damn good idea IMO

definitely something we should be working towards big time. Not far fetched at all really.


also why the fuck arent space ships nuclear powered? is there something i am unaware of about that?
