I would love to hear from anyone with a real clue about what will happen as a likely outcome once the reactor(s) melt(s) down. As with other atomic disasters there is collateral damage. What makes Japan unique? Thanks in advance
The Chernobyl disaster was a nuclear accident that occurred on 26 April 1986, at the Chernobyl Nuclear Power Plant in Ukraine (then in the Ukrainian Soviet Socialist Republic, part of the Soviet Union). It is considered the worst nuclear power plant accident in history and is the only level 7 event on the International Nuclear Event Scale. The disaster occurred on 26 April 1986, at reactor number four at the Chernobyl plant, near the town of Pripyat in the Ukrainian Soviet Socialist Republic, during a systems test. A sudden power output surge took place, and when an attempt was made for emergency shutdown, a more extreme spike in power output occurred which led to a reactor vessel rupture and a series of explosions. This event exposed the graphite moderator components of the reactor to air and they ignited; the resulting fire sent a plume of radioactive fallout into the atmosphere and over an extensive geographical area, including Pripyat. The plume drifted over large parts of the western Soviet Union, Eastern Europe, Western Europe, and Northern Europe. Large areas in Ukraine, Belarus, and Russia had to be evacuated, with over 336,000 people resettled. According to official post-Soviet data, about 60% of the fallout landed in Belarus.
Hmmm, well I don't know about that, I studied the mechanics of a nuclear reactor and radiation in high school physics classes, but I don't know much about the results of a meltdown. Wouldn't it be some what similar to the Chernobyl disaster? My guess is radiation would devastate the surrounding areas and the fallout would also be quite deadly within a reasonable radius. The hardest hit area would remain a waste land for decades.
Basically the meltdown will escape containment, melt through the floor and supposedly down through to the core of the earth - meaning - bye bye!

Shiomi said that even if there was a meltdown, it wouldn't affect humans outside a six-mile (10-kilometer) radius.
An official with Japan's nuclear safety commission says that a meltdown at a nuclear power plant affected by the country's massive earthquake is possible.
Ryohei Shiomi said Saturday that officials were checking whether a meltdown had taken place at the Fukushima Daiichi power plant, which had lost cooling ability in the aftermath of Friday's powerful earthquake.
If the fuel rods melted or are melting, a breach could develop in 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, experts said.
