One material that can be used to cool down a nuclear meltdown is water. It is commonly used as a coolant in nuclear reactors to absorb excess heat. Other materials like liquid sodium or helium may also be used in some reactor designs.
The largest nuclear plant meltdown happened at the Chernobyl Nuclear Power Plant in Ukraine on April 26, 1986. The explosion and subsequent fire released large amounts of radioactive material into the atmosphere, resulting in one of the worst nuclear disasters in history.
If water stopped flowing through a nuclear reactor, the cooling system would fail, leading to a buildup of heat. This could result in the fuel rods overheating and potentially melting down, causing a severe nuclear accident like a meltdown. Cooling water is essential for regulating the temperature and preventing the reactor from overheating.
A partial meltdown is a term for a type of severe nuclear reactor accident. In this situation, the cooling and safety systems of a reactor have failed to the point where the core overheats severely. In this instance, the nuclear fuel, which is welded inside tubes or plates, becomes so hot that it melts its way through the metal (called cladding) encasing it. This contaminates the whole reactor with highly radioactive material. A partial meltdown is generally contaned within the reactor vessel or the containment structure. But the reactor and associated cooling systems will end up highly contaminated with radioactive materials and be unusable.
NRX was a heavy water moderated, light water cooled, nuclear research reactor at the Canadian Chalk River Laboratories, which experienced one of the world's first major reactor accidents on 12 December 1952. The reactor began operation on 22 July 1947 under the National Research Council of Canada, and was taken over by Atomic Energy of Canada Limited (AECL) shortly before the 1952 accident. The accident was cleaned up and the reactor restarted within two years. NRX operated for 45 years, being shut down permanently on 8 April 1993[3]. It is currently undergoing decommissioning at the Chalk River Laboratories site.
Water is commonly used to cool the reactor in nuclear power stations. This water absorbs the heat generated by the nuclear reactions and carries it away, preventing the reactor from overheating. The cooled water is then circulated back to the reactor to continue the cooling process.
Meltdown is a term that describes the melting of a nuclear-reactor core as a result of a nuclear accident

Yes it can. If a nuclear power plant melts down radioactive material is put into the atmosphere, land, water. A good example of this is in Russia where Chernobyl had a meltdown. Nothing can live there today and won't for another 100 years.
because, the nuclear reactors in the facility need to be cooled with water but since the power went out they cant cool it down and if they don't, it could cause an explosion causing radiation to spread across the area like in chernobyl and it will have to stay uninhabited because the radiation will stay for thousands of years
It might be possible to avoid a nuclear meltdown using liquid nitrogen, but you'd have to have an ocean of it. Liquid nitrogen is very cold (obviously), but it does not have a high heat capacity and you'd boil it off very quickly. This means you'd have to have a zillion gallons of LN2 to make a stand to head off a meltdown. Water is a better choice, and there is plenty of it around.To use water, all you have to do is have plumbing and electricity to deliver it. Which can be a problem if a natural disaster occurs, like it did in Japan. Fukushima 1 has three reactors that have melted down. We'll have to wait a while to see what the full effects will be.
Fission products and unused fuel were lofted by the smoke of the burning graphite moderator. This fell back down as fallout (not much different from fission bomb fallout, although no nuclear explosion was involved).
Lead graphite is a suitable material for use in nuclear reactors due to its ability to slow down neutrons, which is important for sustaining nuclear reactions. Lead also has good heat transfer properties, helping to cool the reactor. Additionally, graphite is a stable and strong material that can withstand high temperatures and radiation levels in a reactor environment.

Cooling water is essential for regulating the temperature and preventing the reactor from overheating.
Water is used in nuclear REACTORS both as the heat energy carrier and as a coolant to prevent overheating. Proper cooling is required or the reactor will overheat, causing a meltdown. This is not the same as a nuclear explosion since all that will happen is the extreme heat will melt or destroy the reactor or its containment, but due to the design of reactors it is impossible to have a nuclear explosion similar to nuclear weaponry in a reactor. A notable reactor meltdown was Chernobyl where the nuclear reaction was allowed to generate too much excess heat and the heat caused melting of reactor components and eventually a steam explosion (water vapour explosion) due to overheating. The main concern for a reactor meltdown is not the immediate destruction of everything in a certain radius but the spraying of highly radioactive materials found only in a reactor over a large radius since this radioactive waste cannot be cleaned effectively and will render the surroundings uninhabitable for decades.

The opposite of telophase is prophase. In prophase, the genetic material condenses and the nuclear envelope breaks down, while in telophase, the genetic material decondenses and the nuclear envelope reforms.
