In an interview with Mark Hibbs, a Berlin-based senior associate at the Carnegie Endowment for International Peace, a nonprofit think tank, Newsmax magazine asks – what happens next at the Fukushima Nuclear Power Plant. The answer according to the nuclear expert, is that as Fukushima is now well on its way to a full core-melt nuclear accident, a worst case scenario could possibly lead to the same results last seen in 1986 Chernobyl.
Below we present a brief overview of the Fukushima plant from Wikipedia:
The Fukushima I Nuclear Power Plant (Fukushima I NPP, 1F), often referred to as Fukushima Dai-ichi, is a nuclear power plant located in the town of Okuma in the Futaba District of Fukushima Prefecture. With six separate units located on site with a combined power of 4.7 GW, Fukushima I is one of the 25 largest nuclear power stations in the world. Fukushima I is the first nuclear plant to be constructed and run entirely by The Tokyo Electric Power Company (TEPCO).
Fukushima II Nuclear Power Plant, 11.5 kilometres (7.1 mi) to the south, is also run by TEPCO.

“What happened in Japan is very alarming because it would appear . . . that about 2:30 this afternoon Japan time, when the earthquake struck . . . three of the reactors that were operating were disenabled because of a loss of offsite power that was caused by the earthquake.”
The Japanese situation appears to be roughly analogous to the Three Mile Island incident in the United States, where authorities struggled for days to contain an improperly cooled reactor core but were able to avert a widespread release of nuclear material.
“We were in a situation as I recall then very similar to where we are now, where we were told by news media in 1979 that there was a core melt accident unfolding, we didn’t know how serious it would become, and what would happen,” Hibbs tells Newsmax.
They have 24 hours or so to avoid a core meltdown, he says. But if one occurs, two scenarios could follow: The good outcome would mirror what happened at Three Mile Island, while the bad one could involve what he called a “Chernobyl scenario, where the damage to the reactor was such that the integrity of the structures were damaged.
“So that is the ultimate worst-case scenario. Nobody is saying that’s going to happen. Nobody is even saying we’re going to have a core meltdown. But we have a window of time now. We don’t know how much is left — but the Japanese authorities and the government and all the agencies that they can muster are working overtime to get cooling systems on that site powered and working.”
