Yesterday, HP line, Trains & buses was down.
building was shaking in tokyo..
road and street was packed with ppl.
I have to walk abt 3 hrs to reach home as by taking train only need 20mins.
The news was all over the channel.....
Today everyone is starting to buying and store their foods, water and etc supply....
They are worry the electric, water and foods supply will be cut.

I read a report that the nuclear power plant works are attempting to cool the reactors by feeding it with a mixture of both sea water and boric acid. The boric acid will supposedly counteract the sea water and ensure that the salt from within will not react to produce a working circuit.
In all fairness, i think most of the Japanese are more concerned about the state of the nuclear power plants. Food, water and electrical shortages can be dealt with in time, but if lethal amounts of radiation start leaking from the nuclear power plants. it can take up to years or generations for the radiation levels to subside. Not to mention that leaking radiation will directly affect what remains of Japan's food and water supplies.
Let's hope the Japanese can work quickly to secure the nuclear plants for any further mishaps within the next 24-72 hours.

Yes... they are working very hard on it now....
The 13 backup diesel plants failed. Supposed to pump coolant. It is a lesson for nuclear plant designers. A rethink for those countries thinking of setting up a nuclear power plant. Everyone thinks 13 backups sure fail-safe. Well, think again. Think Chernobyl and before that, 3MileIsland.

In just a few weeks, this disaster will simply become a distant memory in the minds of many people unaffected around the world.
Who still recall the Haiti earthquake that took the lives of over 300,000 souls just a year ago?

Don't compare Japan's nuclear plants to Chernobyl.
Chernobyl was a completely different system as opposed to Japan's plants. Japan's nuclear plants are what is known as light water plants, and their radioactivity levels are regulated by the introduction of water into the system.
In the worst case scenario of a nuclear reactor core explosion., the superheated water merely vapourizes into a gigantic cloud of radoactive steam which can be quickly dispersed by air currents.
Chernobyl, on the other hand, uses graphite to contain radioactivity levels. When the incident at Chernobyl took place, the explosion blasted the graphite into ultra fine particles, which, unlike steam, tend to linger in the air a lot longer and settle in at much higher concentrations. That explains why Chernobyl remained radioactive for so long.

Not exactly, it was the explosive ejection of nuclear fuel debris and resulting fire in the exposed core of the No. 04 reactor which had then resulted in large quantity of radioactive isotopes being released into the atmosphere that constitute the majority of fallout contamination in the Chernobyl nuclear meltdown accident.
... and neither was the graphite moderator "blasted into ultra fine particles".
Grigorii Khmel said:
We arrived there at 10 or 15 minutes to two in the morning ... We saw graphite scattered about. Misha asked: "What is graphite?" I kicked it away. But one of the fighters on the other truck picked it up. "It's hot," he said. The pieces of graphite were of different sizes, some big, some small enough to pick up ...

well. then if we wanna realllllly see....... have to look at the respective halflifes and try to figure out when they decay until a relatively safe level.
i'm suspecting that steam would actually decay faster compared to the carbons.

In an unlikely event of a breech in the Unit 01 Boiling Water Reactor (BVR) reactor vessel of the Fukushima I Nuclear Power Plant and its surrounding containment structure following a meltdown will eventually result in the release and dispersion of primarily Iodine-131, Strontium-90 and Caesium-137 radiacotive isotopes with a half-life of 8.02 days, 28.8 years and 30.1 years respectively into the environment.
Iodine-131 is the deadliest of the three and may result in thyroid cancer thus the stocking up of potassium iodide tablets by the Japanese government as a countermeasure but it has a relatively short half-life of only 8.02 days. It is Strontium-90 and Caesium-137 that will be of a major concern as they will eventually be deposited back into the earth, reintroduced into the food chain and accumulate within the bodies of the local populace - irradiating them from within.

Boron, not boric acid.
Fate is kind to Libya's current rulers. Now the world's media got a bigger and more sensational Japan earthquake and damaged nuclear reactor story to chase, to fill the TV screens with breaking news and to have full day non-stop news coverage. Suddenly, no one cares about the Libya situation anymore. So now, he can wipe them out quietly. That's how fickle news hounds can be.

good analysis.
it would take abt.......... i think a good month before iodine levels go back to safe lvls. on the other hand. strontium and caesium looks really heavy...
