also their are gen1, gen2, and gen3 reactors for a reason... they improve over time.
we had to start somewhere, and they are only getting better.
i hope that the engineers who built these power plants will study everything that has happened from this disaster to make the next generation even better, as well as upgrading all of the current power plants.

Update: Here is a little information on what we really know has happened regarding the nuclear reactors in Fukushima.
There is a possibility that one or more of the reactors will meltdown. A meltdown does not mean that radiation will fly all over the place Chernobyl-style. Reports indicate that the primary containment vessel remains intact.
A small amount of radiation leaked this morning. It is only apparently enough to be dangerous to people in the immediate area, but residents within 30-kilometers have been evacuated as a precaution.
Chief Cabinet Secretary Yukio Edano said a fourth reactor at the complex was on fire and more radiation had been released.
He said the reactor, even though it was unoperational, was believed to be the source of the elevated radiation release because of the hydrogen release that triggered the fire.
“Now we are talking about levels that can damage human health. These are readings taken near the area where we believe the releases are happening. Far away, the levels should be lower,” he said.
“Please do not go outside. Please stay indoors. Please close windows and make your homes airtight. Don’t turn on ventilators. Please hang on your laundry indoors,” he said.
“These are figures that potentially affect health, there is no mistake about that,” he said.
He said a reactor whose containment building caught fire Monday has not contributed greatly to the increased radiation. The radiation level around one of the reactors stood at 400,000 microsiverts per hour, four times higher than the safe level.
Officials said 50 workers are still there trying to put water into the reactors to cool them. They say 800 other nonessential staff were evacuated.
The 400,000 microserverts (400 millisieverts) per hour reading was taken right next to the reactor in question. What does that mean? Here is a very good explanation from Gakuranman, who has been updating a very informative liveblog on the subject: http://gakuranman.com/great-tohoku-earthquake/
Remember, although these figures may suggest that the level of radiation being recorded at Fukushima is not extremely high, the danger is constant exposure over a period of time. For this reason, people within the 20km evacuation zone are at high risk of serious harm.
7,000-10,000 millisieverts – Person dies from radiation poisoning. (Full body exposure).
1,000 – Nausea and vomiting (Full body exposure).
500 – Will reduce levels of peripheral blood lymphocytes (white blood cells that defend your body) (Full body exposure).
200 – No clinical conditions confirmed below this number
10 – Radiation from the sun
6.9 – CT scan
2.4 – 1 year’s worth of natural radiation
0.6 Stomach X-ray
0.2 – A return air trip from Tokyo to New York
0.05 – Chest X-ray (or the level of radiation expected to be maintained around a nuclear power plant)
At this point, there is nothing indicating that anything close to a dangerous amount of radiation is being blown towards Tokyo.

i think this one may be a little higher right now...
Is anyone else confused

Probably that's sun radiation outside the atmosphere.Is anyone else confused
On another note, my country is neighbouring Ukraine and Chernobyl is around 800Km from here. The 1986 disaster's effects are visible if you pay attention even if nobody bothered to run a full study, the numbers of cases of leukemia and thyroid disfunctions/cancer have increased in the last 2 decades; and we weren't even in the way of radioactive winds. Water is usually the way radiation enters the body, either as rain or contaminated drinking water.

1,000mSv – Nausea and vomiting (Full body exposure).
500mSv – Decrease of lymphocytes in peripheral blood (white blood cells that defend your body) (Full body exposure).
200mSv – No clinical conditions confirmed below this number
10mSv – 1 year’s worth of natural radiation (Brazil)
6.9mSv – CT scan
2.4mSv – 1 year’s worth of natural radiation (world average)
1mSv – Limit of one’s year’s exposure to non-natural radiation (excluding medical examinations)
0.6mSv – Stomach X-ray
0.2mSv – A return air trip from Tokyo to New York
0.05mSv – Chest X-ray (or the level of radiation expected around a nuclear power plant – in practice it is much lower than this)

le sigh.
There is a big difference between a hydrogen/oxygen explosion that has banged up some piping and blown the walls off the structure versus the week long burn of the graphic moderator at Chernobyl. The plume from the burning core was what spread all the isotopes across the globe. A quick explosion might scatter some material around the immediate vicinity but it won't create a several kilometer plume to lift such nasty crap into the air.
I've read here and there people saying these particular reactors didn't have the gigantic concrete catch can sitting below the containment vessel to catch the melting core. I don't know if this is true or not but if it is true it means the core could melt through the bottom of pressure vessel, containment vessel and the foundation of the building. If this happens then there is risk of groundwater contamination which is very bad. Still won't affect you in Taiwan
well, that was before the news section crackdowns
i gotta say tho, the stricter moderation does work...
xs is one of the most civil forums i know of... the worst ive seen here is debating each others iq and calling each other doo-doo-heads ^^
yeah well, we are all geeks after all
EDIT: so the worst thing that could happen, as a meltdown core breach is supposedly impossible, is that the cores still get breached somehow... right?
that would result in radioactive material escaping the core... sounds just like chernobyl to me, just not as severe and more slowly like a cracked pressure cooker...
and other than chernobyl there are 4 reactors which, COULD, all crack and release radioactive material...
im really a little nervous about this...
better safe than sorry...
This. People are now judging nuclear power by the gradual failure of this plant that was designed half a century ago. In my book the designed facility did a damn good job of gradually failing when mother nature threw a 8.9 magnitude earthquake, hundreds of aftershocks, oh.. and thating 30 foot tall wall of water. Yeah, I'd say they did a pretty good job all things taking into account. Now I just hope the next set of generators at a coastal plant will be waterproof
