One worst case scenario would be a meltdown in which an explosion puts the entire contents of the reactor into the atmosphere. As bad as the Chernobyl disaster was, only a part of the material in the reactor got into the atmosphere. This was in large part because several people went into a water pool below the reactor to drain it, knowing the job would quickly kill them. If the molten metals in the reactor had got into the water, the steam explosion would have sent a large part of it into the air.
We know there were agricultural losses as far away (and upwind) as Scotland, and complete losses of herds in Finland, many hundreds of miles from the plant. We know that thousands of square miles of land were rendered unfit for use for years, and many square miles almost permanently. Estimates for the economic loss from Chernobyl run as high as a trillion 1995 dollars. Twenty years after the event, Belarus was still putting 20% of its money into cleanup. Clearly, a worse disaster would be very bad. An equivalent failure in the US would cost a multiple of the amount of money.
The spent fuel pools of US reactors are considered a weak part of plant design and cause considerable anxiety over security. Of the 103 plants currently operating, only six have spent fuel pools hardened against impact of a six ton aircraft, and only one is hardened against impact of a large commercial airliner. The US has not decided how to deal with nuclear waste, and, as a result, most of the waste is in spent fuel pools. Impact of a large commercial airliner into one of these structures might cause a "worst case scenario" of scale similar to Chernobyl. This is an object of widespread discussion in public forums on nuclear energy, such as town meetings currently happening in Vermont over whether the Vermont Yankee plant should have its license renewed. There have been rumors that the 9-11 terrorists considered hitting such a plant, but decided against it because it would cause to much harm to their cause.
In the 1980s, a nuclear reactor exploded and burned near the town of Chernobyl in the former Soviet Union, now located in Ukraine. The Chernobyl disaster on April 26, 1986, is considered one of the worst nuclear accidents in history.
The nuclear reactor that exploded and burned in the 1980s was located near the town of Chernobyl in Ukraine. The Chernobyl disaster, which occurred in 1986, released a significant amount of radioactive material into the environment and is considered one of the worst nuclear accidents in history.
The Chernobyl Nuclear Power Plant underwent a level 7 event - the worst accident so far. The plant, located in the Soviet Union near Pripyat in Ukraine lost its number four reactor on 26 April 1986. A link to the Wikipedia article on the accident is provided.
Nuclear energy can be considered one of the worst sources of energy due to the potential for catastrophic accidents, long-term environmental impact from radioactive waste, and concerns about nuclear proliferation.
Accidents in nuclear reactors can include events like meltdowns, core breaches, and radiation leaks. These accidents can lead to the release of radioactive material into the environment, posing serious health and environmental risks. Safety measures and protocols are in place to prevent such accidents and minimize their consequences.
the reactor accident at the chernobyl nuclear power plant.
In the 1980s, a nuclear reactor exploded and burned near the town of Chernobyl in the former Soviet Union, now located in Ukraine. The Chernobyl disaster on April 26, 1986, is considered one of the worst nuclear accidents in history.
The #4 reactor is the reactor at the Chernobyl Nuclear Power Plant (Pripyat, Ukraine) that exploded on April 26, 1986. It is still the worst nuclear accident to ever take place anywhere.
The nuclear reactor that exploded and burned in the 1980s was located near the town of Chernobyl in Ukraine. The Chernobyl disaster, which occurred in 1986, released a significant amount of radioactive material into the environment and is considered one of the worst nuclear accidents in history.

The answer your probably looking for is 'melt down' however a melt down is a very rare event and the worst form of 'nuclear accident'.
Worst reactor accident to that date. The Japanese 2011 accident may turn out to be worse however.
A nuclear reactor exploded in 1986 at the Chernobyl Nuclear Power Plant in Ukraine. The explosion released a large amount of radioactive material into the atmosphere, making it one of the worst nuclear disasters in history.
The Chernobyl disaster was a nuclear accident that occurred on April 26, 1986, at the Chernobyl Nuclear Power Plant in Ukraine (then part of the Soviet Union). It is considered the worst nuclear disaster in history. The explosion and resulting fire released large amounts of radioactive particles into the atmosphere, causing widespread contamination and significant health and environmental impacts.
Nuclear energy can be considered one of the worst sources of energy due to the potential for catastrophic accidents, long-term environmental impact from radioactive waste, and concerns about nuclear proliferation.
Three mile island was the site of the worst nuclear 'accident' in america's history. The reactor went into meltdown - releasing radioactive material into the atmosphere.
A nuclear disaster would be the melt down of a nuclear power plant, possibly resulting in an explosion. A melt down is exactly what it sounds like it means, when a critical component of the reactor literaly melts, buckles or bends from the strain and heat, and fires are usually started as a result. This can cause other structural failures, which can ultimately lead to either complete structural failure or, in a worst case scenario, if the safety backups fail to trigger, the loss of control of the reactor, which may lead to the reactor exploding.
