8.8 Magnitude Earthquake hit Japan

Random dude on the site. There are quite a few knowledgeable people on there though, and it wouldn't surprise me if some in that thread are in the nuclear power industry.

It's pronounce nu-cu-lar.

i was on a nuclear sub in the navy and i know how important the primary and secondary cooling loops are to a reactor

the diesels were the 2nd to last resort as far as keeping the reactor cool(to my knowledge), last option is batteries but they can only run those big pumps for so long. if those diesels got swamped while running they are most likely trashed

In other news, Sushi reaches an all time high. Plan to shell out over $100 for a single meal.

I thought the same but check this thread. It's the 7th post down that says the same thing and it hasn't been edited.

They decided to F it and fill the reactor w/ seawater.

Japan to fill leaking nuke reactor with sea water

TOKYO, March 12 (Reuters) - Tokyo Electric Power Co plans to fill a leaking reactor at the Fukushima Daiichi power plant with sea water to cool it down and reduce pressure in the unit, Japan's top government spokesman said on Saturday.

"The nuclear reactor is surrounded by a steel reactor container, which is then surrounded by a concrete building," Chief Cabinet Secretary Yukio Edano said.

"The concrete building collapsed. We found out that the reactor container inside didn't explode."

Japan earlier in the day warned of a meltdown at the reactor at the plant, damaged when a massive earthquake and tsunami struck the northeast coast, but said the risk of radiation contamination was small.

"We've confirmed that the reactor container was not damaged. The explosion didn't occur inside the reactor container. As such there was no large amount of radiation leakage outside," he said.

"At this point, there has been no major change to the level of radiation leakage outside (from before and after the explosion), so we'd like everyone to respond calmly," Edano said.

"We've decided to fill the reactor container with sea water. Trade minister Kaieda has instructed us to do so. By doing this, we will use boric acid to prevent criticality."

Edano said it would take about five to 10 hours to fill the reactor core with sea water and around 10 days to complete the process.

Edano said due to the falling level of cooling water, hydrogen was generated and that leaked to the space between the building and the container and the explosion happened when the hydrogen mixed with oxygen there.

glad we dont have to deal with any of that shit here in texas

We think we're so big and bad as a species..

(CNN) -- The powerful earthquake that unleashed a devastating tsunami Friday appears to have moved the main island of Japan by 8 feet (2.4 meters) and shifted the Earth on its axis.

"At this point, we know that one GPS station moved (8 feet), and we have seen a map from GSI (Geospatial Information Authority) in Japan showing the pattern of shift over a large area is consistent with about that much shift of the land mass," said Kenneth Hudnut, a geophysicist with the U.S. Geological Survey (USGS).
Reports from the National Institute of Geophysics and Volcanology in Italy estimated the 8.9-magnitude quake shifted the planet on its axis by nearly 4 inches (10 centimeters).
The temblor, which struck Friday afternoon near the east coast of Japan, killed hundreds of people, caused the formation of 30-foot walls of water that swept across rice fields, engulfed entire towns, dragged houses onto highways, and tossed cars and boats like toys. Some waves reached six miles (10 kilometers) inland in Miyagi Prefecture on Japan's east coast.

The quake was the most powerful to hit the island nation in recorded history and the tsunami it unleashed traveled across the Pacific Ocean, triggering tsunami warnings and alerts for 50 countries and territories as far away as the western coasts of Canada, the U.S. and Chile. The quake triggered more than 160 aftershocks in the first 24 hours -- 141 measuring 5.0-magnitude or more.
The quake occurred as the Earth's crust ruptured along an area about 250 miles (400 kilometers) long by 100 miles (160 kilometers) wide, as tectonic plates slipped more than 18 meters, said Shengzao Chen, a USGS geophysicist.
Japan is located along the Pacific "ring of fire," an area of high seismic and volcanic activity stretching from New Zealand in the South Pacific up through Japan, across to Alaska and down the west coasts of North and South America. The quake was "hundreds of times larger" than the 2010 quake that ravaged Haiti, said Jim Gaherty of the LaMont-Doherty Earth Observatory at Columbia University.
The Japanese quake was of similar strength to the 2004 earthquake in Indonesia that triggered a tsunami that killed over 200,000 people in more than a dozen countries around the Indian Ocean. "The tsunami that it sent out was roughly comparable in terms of size," Gaherty said. "[The 2004 tsunami] happened to hit some regions that were not very prepared for tsunamis ... we didn't really have a very sophisticated tsunami warning system in the Indian Ocean basin at the time so the damage was significantly worse."
The Japanese quake comes just weeks after a 6.3-magnitude earthquake struck Christchurch on February 22, toppling historic buildings and killing more than 150 people. The timeframe of the two quakes have raised questions whether the two incidents are related, but experts say the distance between the two incidents makes that unlikely.
"I would think the connection is very slim," said Prof. Stephan Grilli, ocean engineering professor at the University of Rhode Island.

Some more good perspective:

You know, the crazy thing is we (and the MSM) are focusing on the nuke plant. Obviously some of us have a particular interest in that.

But the number of injuries and deaths from the problem at that plant will be insignificant, literally round off error to the death toll, compared to the inahalition of the coastal cities in Northern Japan.

Maybe because the earthquake destruction, the Tidal Wave destruckion is so had to mentally get around, it is easier to focus on the nuclear "oh no the sky is falling" coverage. But that isn't the major, or important story out of Japan today.

"At the Fukushima plant, the amount of radiation reached around 1,000 times the normal level in the control room of the No. 1 reactor, and 140 times the normal level near the main gate of the plant at one point. It was the first time an external radioactive leak had been confirmed since the disaster."

Normal background is 2.4 mSv/yr = 0.24 REM/yr =0.66 mREM/day = 0.0274 mREM/hr.

At the main gate of the plant the radiation was 140 x 0.0274 = 3.836 mREM/hr = 0.00386 REM/hr = 0.0386 mSv/hr = 38.6 uSv/hr

Meh...........not even sunburn



I really, really wish I had accurate up to date info, so I could say for sure, but as i have said numerous timesI this is bad, but not life threatening IF it's going as advertised. Other than the talking heads spewing filth, the news reports are consistent with what would likely happen in an accident like this.

I'm just trying to stay independent, unbiased, as much as I can for a guy who has spent his entire life in the nuclear industry, then try to filter through the garbage pit that is the information being put out, and give you guys some type of sensible opinion on what is going on.

I could be waaaaaaaaaaaaaaaay wrong on all of it. For the sake of everybody, I hope I'm not.

I'm using news release directly from TEPCO and World Nuclear News. They are a million times more reliable than mainstream media. To someone who works in a nuke, the detail in the TEPCO press releases are enough for me to see what is going on.

Let's hope they are being honest. They can't get out of this, if it's a lie. It will be there for all to see. We have US Navy off the coast monitoring things. They can't get away with too much without somebody knowing.

Media skewing things. What else is new.

Counterpoints:


1.
"For comparison, a 1 megaton surface blast will produce 3000 Rem fallout at 30 miles and 90 Rem at 250 miles.
The US west coast will see radiation levels nowhere near that amount.
miles."

2.
"For you guys in WA/OR, just a point of reference. The Chinese above ground bomb tests (including their H bomb tests) were readily detectable (surface deposition) above US regulatory limits on the West Coast. And this fact is pretty much "meh" and noone knows it.
If, and I emphasize if, there is a substantial release it may be detectable, but the effect several thousand miles away will be negliable to nonexistant. The distance is just too too far."
