Can a nuclear reactor explode as a nuclear bomb?
Highly unlikely if not altogether impossible. In a core meltdown, you might see a steam explosion if the core melts and breaches the containment structure and hits say cooling water. But even a runaway chain reaction in a reactor would not cause a nuclear explosion like a bomb.
What is a dangerous conditions caused by overheating inside of reactor called?
A dangerous condition caused by overheating inside a reactor is known as a meltdown. This occurs when the core of the reactor becomes so hot that it melts, potentially leading to a breach of containment and release of radioactive material.
In a nuclear reactor meltdown what melts?
The short answer is that at least the fuel melts, but if it can melt anything else, it does, including concrete. There are different types of meltdowns. At Three Mile Island, the meltdown happened when hot steam reacted with the zirconium cladding of reactor rods. This allowed uranium fuel pellets to come into contact and melt together. Upwards of half of the fuel in the reactor melted. A worse case is if the reactor itself melts, so the nuclear fuel can go through it. In Chernobyl, the reactor was opened by a series of explosions caused by steam and chemical reactions. Molten fuel escaped the reactor, and there was a threat that when it melted through the concrete floor the reactor stood on, it would fall into a water containment below. If this had happened it almost certainly would have caused another explosion and a much worse disaster. Fortunately for all of us who are alive, a number of people went into the area of the disaster, knowing they would be killed as a result, to get the water out of the containment under the reactor. The molten fuel combined with other materials, and was diluted in the process, finally solidifying in the area under the reactor. As a matter of interest, other people also worked to contain the radioactive material, knowing the work would kill them. Some of these people lived as long as six weeks in the hospital, and some hospital workers came down with radiation poisoning as a result of this exposure. The disaster workers who died were buried in graves over 300 feet deep to isolate the radiation in their bodies.
What is a radioactive meltdown?
A radioactive meltdown occurs when the core of a nuclear reactor overheats and melts due to a loss of cooling capacity, releasing large amounts of radioactive materials into the environment. This can lead to severe environmental contamination and health hazards for nearby populations.
What happens when a nuclear reactor core overheats and melts?
the coolant is contaminated with fission productsif the coolant is water and the fuel pellets are canned in zirconium a chemical reaction may occur that could generate large amounts of hydrogen gasif enough core is exposed without coolant, the molten core material could melt through the reaction vessel and eventually the floor of the containment building (this is very unlikely unless there was a severe loss of coolant accident and the emergency coolant system was disabled)

What does the term melt down refers during a nuclear disaster?
The term melt down is a fairly literal description of what can happen when the cooling systems of a nuclear reactor fail; the reactor core becomes so hot that the whole thing literally melts into a puddle of radioactive slag.

What changes when ice cubes melts?
a ice cube melts when it heats up

What going to happen if the nuclear power plant melts down?
A meltdown is both good and bad:Good reactor design uses the meltdown to disassemble the fuel into a subcritical mass, causing the reactor to automatically shutdown.Bad reactor design can allow the fuel to enter places it should not go, possibly causing steam explosions, contamination outside the reactor containment, etc.
How did the earthquake in Japan affect the people in Canada?
A lot more Canadians than you think live in Japan and there are Canadian deaths and if the nuclear reactor melts down then the radiation may travel here.
What are the causes of nuclear disaters?
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.
Why does butter melt?
Butter is a water-in-fat emulsion, when it heats up the fat melts.

What is a core meltdown?
A core meltdown is a severe nuclear accident that occurs when the fuel rods in a reactor reach a temperature high enough to cause the nuclear fuel to melt, potentially breaching the containment structure. This can lead to the release of radioactive material into the environment with serious consequences for public health and the environment.
