    Same. But there was similar optimistic reports earlier today that proved false.

    News I've been watching has a big helicopter over the reactor lowering something in. Still over 800 people missing and the body count is rising. If any radiation makes it to PRK, their dictator could do something stupid to retaliate against Japan. Final report on our tsunami here: 20-22 cm (less than a foot).
    Godzilla is extremely pertinent; but if a movie is made, the monster causing all this devastation will be defeated by Godzilla, saving Japan and the world.

    Ever since the events in Egypt, I've been checking up on Al Jeezera a lot, they've been really great in their coverage of multiple events-unlike American news agencies.

    Japan authorities: TEPCO plant fuel rods may have melted -Jiji

    http://www.reuters.com/article/2011/...00707420110312

    March 12 | Sat Mar 12, 2011 12:38am EST

    March 12 (Reuters) - Japanese nuclear authorities said that there was a high possibility that nuclear fuel rods at a reactor at Tokyo Electric Power's Daiichi plant may be melting or have melted, Jiji news agency reported.

    Experts have said that if the fuel rods have been damaged, it means that it could develop into a breach of the nuclear reactor vessel and the question then becomes one of how strong the containment structure around the vessel is and whether it has been undermined by the earthquake.

    BBC is reporting that Fukushima Prefecture is being evacuated but they're not sure if a meltdown occured. Cell phone companies are giving free calls to help out. The GOJ now says probably more than 1000 deaths. There are two plants with big problems. This according to BBC and their sources (except the phone deal, which I saw on TV).

    Hopefully the containment structure will be able to help..

    Or:

    "No Chernobyl is possible at a light water reactor. Loss of coolant means a temperature rise, but it also will stop the reaction," Naoto Sekimura, a professor at the University of Tokyo, said.

    "Even in the worst-case scenario, that would mean some radioactive leakage and equipment damage, but not an explosion. If venting is done carefully, there will be little leakage. Certainly not beyond the 3 km radius."

    The article says plant 2.

    The cooling system failed at three reactors of the quake-hit Fukushima No. 2 nuclear power plant Saturday, the operator Tokyo Electric Power Co. said.

    The company, which has already scrambled to deal with radiation leaks at its Fukushima No. 1 plant, notified the industry ministry that the failsafe system at the No. 2 plant stopped functioning as the temperature of coolant water has topped 100 C.

    Factbox: What happens when a reactor loses coolant

    http://www.reuters.com/article/2011/...1?pageNumber=1

    (Reuters) - Several nuclear power reactors in Japan shut as designed following the massive earthquake off the nation's northwest coast, but the failure of a back-up power generator at one unit risks a radioactive leak.

    Operators at Tokyo Electric Power Co (Tepco) are still working to control the situation at one of their plants.

    Tepco said at about 2:46 p.m. local time Units 1, 2 and 3 at its Fukushima Daiichi plant -- three of six at the plant -- shut following the earthquake. All are boiling water reactors.

    Tepco said the reactors shut due to the loss of offsite power due to the malfunction of one of two off-site power systems. That triggered the emergency diesel generators to startup and provide backup power for plant systems.

    About an hour after the plant shut down, however, the emergency diesel generators stopped, leaving Units 1, 2 and 3 with no power for important cooling functions.

    Nuclear plants need power to operate motors, valves and instruments that control the systems that provide cooling water to the radioactive core.

    Tepco declared an emergency and the government ordered thousands to evacuate the area, while engineers worked to restore power. The company is bringing in mobile generators to restore the power supply, but pressure inside the containment of Unit 1 continued to increase.

    Early on Saturday Tepco said it had lost the ability to control pressure at the No. 1 and 2 reactors.

    -----------------------------------------------------

    NORMAL OPERATIONS

    * In a reactor operating normally, pumps circulate water through the reactor core to keep the rods from overheating. The temperature inside a reactor operating normally is about 550 degrees F (285 C).

    See www.nrc.gov/reactors/bwrs.html on the U.S. Nuclear Regulatory Commission site for diagrams on how water moves through a boiling water reactor operating normally.

    ORDERLY SHUT DOWN

    * When a reactor shuts, pumps continue to move water over the fuel rods. The electricity to run the pumps usually comes from off-site power supplies brought in by transmission lines.

    But, if the power lines fail, the plants have redundant on-site power sources, including backup diesel generators and batteries.

    BLACK-OUT

    When all sources of power fail like at the Fukushima Daiichi plant, coolant begins to boil off, exposing the fuel rods. It would likely take several hours to boil off enough coolant before the core is hot enough to damage it.

    If the fuel rods became damaged they would release radioactive material into the remaining coolant.

    - Hours beyond that the metal surrounding the ceramic

    uranium fuel pellets could potentially start

    melting if temperatures reach well beyond 1000 F as

    occurred at Three Mile Island. The ceramic fuel

    pellets would not melt until temperatures reached

    about 2000 degrees F.

    - Hours after the fuel rods started to melt, the heat

    could potentially melt through the reactor vessel,

    which is made of high tensile steel four to eight

    inches thick

    - It would take even more time before the containment

    fails, which could result in radioactive releases

    to the environment. The containment is an air tight

    steel or reinforced concrete structure with walls

    between four to eight feet thick.

    As the Three Mile Island accident showed, operators can regain control of the situation if they can get the coolant flowing again.

    A boiling water reactor works at temperatures and pressures similar to a normal steam boiler, 500-600 degrees and probably about 1200 PSI.

    Now, in a closed loop, single system like a BWR, the steam is condensed back to water, it cannot be released because it's radioactive.

    The feed pumps to pump the water back into the system or add water must be able to pump at a pressure greater than the normal operating boiler pressure.

    If the pressure in the steam loop rises higher than what the feed pump can pump against, you cannot get any more water into the system.

    Thus you start losing cooling water, which makes the problem worse by increasing the pressure as more water flashes off to steam.

    I'd say it's very similar to a crown sheet failure/boiler explosion that happened to steam locomotives from time to time.

    Al Jazera's take on it.

    Supposedly if it's "handled carefully" and vented "properly" there isn't a "chance" of an explosion and the leak would be contained to a 3km radius.

    We'll see how it turns out; hopefully that's correct.
    Nope. No explosion.....except the one CNN just reported at that same power plant.

    Will a government of any country ever tell the truth??

    A ton of marines arrived from Okinawa a month early where I live, they were flown back ASAP. Not sure why, one of them was my co-workers husband.

    Edit: Why no explosion? I'm hearing reports of explosion, do you have a source that goes against this?
