The worst nuclear accident in the United States occurred at the Three Mile Island nuclear power plant in Pennsylvania on March 28, 1979. A partial meltdown of one of the reactors resulted from a combination of mechanical failures, design deficiencies, and operator errors. While there were no immediate injuries or deaths, the incident raised significant concerns about nuclear safety and led to widespread public anxiety regarding the safety of nuclear power.

Due to an accident that began at 4 a.m. on Wednesday, March 28, 1979, Three Mile Island Nuclear Power Plant was Condemned and permanently shut down.
Why did the US slow it's construction of nuclear power plants in the 1980's?
Americans felt less safe after the accident at Three Mile Island.
What event caused the US to slow its construction of nuclear power in the 1980s?
The accident at Three Mile Island on March 28, 1979. Also, storage of the leftover nuclear materials became a problem as no state wanted it stored within their borders.

Was there an Atomic Bomb dropped by accident in the US?
actually many. look up broken arrow, the US codename for a nuclear weapon accident. none had a nuclear explosion, although many had explosions or fires of chemical explosives.
Did a nuclear plant ever exploded in the US?
Yes, the Three Mile Island nuclear power plant in Pennsylvania experienced a partial core meltdown in 1979, which resulted in the most serious accident in the history of the US commercial nuclear power generating industry. However, the reactor did not explode like a nuclear bomb.
How many years passed from the first controlled nuclear reaction to the first nuclear meltdown in US history?
The first controlled nuclear reaction took place in 1942, and the first nuclear meltdown in US history occurred in 1979, marking a span of 37 years between these two events.

What is the ultimate heat sink for nuclear reactors?
"Ultimate Heas Sink" is a vitrually unlimited supply of water that can be used by nuclear reactors to cool vital systems and their primary containment during worse case (design basis) accidents. The US Nuclear Regulatory Commission requires all nuclear plants operating in the US to maintain emergency systems that can remove heat from vital systems in the event of a design basis worse case accident. Designers of nuclear reactors have determined what kind of accident would be the worse possible accident to happen, and they have designed systems to mitigate those accidents. These systems must operate independent of external sources of electricity, or other resources. These systems include (but are not limited to) emergency generators (usually diesel powered), emergency sources of pneumatics, containment structures and suppression pools capable of receiving and suppressing the energy that could be released from the reactor vessel if it ruptured. All of the systems mentioned above either generate heat, or remove heat from other systems and components . This heat must be removed in order for these systems to continue to function. Therefore, each plant must have an "Ultimate Heat Sink" capable of removing heat from the primary containment and other vital systems necessary to mitigate a worse case accident. Usually, the ultimate heat sink is a large body of water such as a river or a lake. If the water level or temperature of the "Ultimate Heat Sink" for a nuclear plant drops to a pre-defined level, or if other conditions exist to where the "Ultimate Heat Sink" cannot provide the required heat removal function, then the nuclear plant is bound by regulation to shut down. The water from the "Ultimate Heat Sink" is passed through large heat exchangers where it cools other mediums. For this reason, the water from the ultimate heat sink does not become contaminated with radioactivity from the nuclear plant.
