In the case of Chernobyl the reactor core exploded, and at Three Mile Island it partially melted.
Both Chernobyl and Three Mile Island are well-known nuclear disasters that caused widespread environmental and health impacts. Both incidents resulted in the release of radioactive materials into the environment and raised concerns about nuclear safety and regulation. Additionally, they both led to significant changes in the nuclear industry and a reassessment of nuclear power plants' safety measures.
In brief, both accidents involve gross failure of a nuclear reactor. The two reactors are of different types, so there are some things that are unique to each plant. Both had the reactor cores damaged catastrophically. And in both cases, radiation was released ourside fuel element cladding and outside containment barriers. What is different is that in the Chernobyl disaster, the atomic pile caught fire. I was built using graphite blocks for moderators. At Three Mile Island (TMI), there was no fire. The radiation released at TMI was some nasty stuff including fission fragments from failed fuel element cladding, but it was released in limited quantities. TMI was an accident. In Russia, things were different. It was a disaster. At Chernobyl, as the core burned, massive clouds of highly radioactive fission byproducts (from the failed fuel elements) were caught up in the fire column and swept aloft with the smoke and heat. This caused the surrounding area to have to be evacuated and some of it was actually abandoned. The small city of Pripyat became a ghost town. This newly constructed community of about 50,000 or so was abandoned. People just walked away. They literally left everything behind and departed with just the clothes on their backs. There were a number of fatalities at Chernobyl, and none at TMI. Some reactor workers and a number of emergency personnel responding to the fire died of radiation sickness. And a number of civilians lost their lives within a few weeks of the accident. One account logged by a helicopter pilot (several choppers dumped water on the fire from aloft) said that in the night, the column of smoke and debris from the fire glowed in the darkness due to the radioactivity. Helicopter pilots were among those who died as a result of their heroic efforts to douse the flames. Links are provided to relevant Wikipedia articles.
The incident is called the XYZ Affair. It took place in 1797 when three French agents, identified only as X, Y, and Z, demanded a bribe and a loan from American diplomats in exchange for stopping French attacks on American ships.
The three main islands of the Italian Peninsula are Sicily, Sardinia, and Capri. Sicily is the largest in the Mediterranean Sea, while Sardinia is the second-largest island and Capri is a smaller island located off the southern coast.
The label given to the offer made by three French ministers in 1798 to renew diplomacy with the US in return for a bribe is known as the XYZ Affair. This incident strained relations between the two countries and led to an undeclared naval war known as the Quasi-War.
The United States had an incident in the Three Mile Island and Ukraine had one in Chernobyl but the results were not compared as the results reached on Japan in world war two.
The primary impact of the three mile island incident was to increase nuclear safety. This has had lasting effects on the industry.

No, not according to an Forbes article that states Chernobyl disaster (level 7 on International Nuclear and Radiological Event Scale) was magnitudes worse than the 2011 Fukushima nuclear disaster in Japan, which was a level 4 and likely be upgraded to a level 5.
The nuclear accident at Chernobyl was more severe and resulted in widespread radioactive contamination and long-term health effects, whereas the accident at Three Mile Island resulted in a partial core meltdown that was contained within the reactor. Additionally, the Chernobyl disaster led to multiple immediate fatalities and a significant evacuation of nearby residents.
Chernobyl has three syllables: cher-no-byl
The president at the time of the Three Mile Island nuclear incident was Jimmy Carter.

1979. You call it disaster, and it was for the plant owners as they lost their investment, but it was not in the same class as the Chernobyl disaster, which really was a disaster.
The reason Chernobyl failed is because the plans used to design the plant were old and out of date. The technology was years behind. Where as Three Mile Island has multiple fail safes. All nuclear reactors have these. If something fails they have a fail safe to stop it, and if that fails there is another; and so on and so on. Three Mile has 4 fail safes, two of which failed and the third caught it preventing disaster.
The incident at Three Mile Island in 1979 involved a partial meltdown of one of the reactors. It was caused by a combination of mechanical malfunctions and human errors. While there was no direct fatalities, the accident led to heightened concerns about nuclear safety in the United States.
