Nuclear fuel is a substance that can produce practical nuclear energy through nuclear fission or nuclear fusion in a nuclear reactor. Heavy nuclear fission and light nuclear fusion are two main ways to obtain practical uranium rod nuclear energy.
Uranium 235, uranium 238 and plutonium 239 are nuclear fuels that can undergo nuclear fission, also known as fission nuclear fuels. Among them, uranium 235 exists in nature, while uranium 233 and plutonium 239 are artificial nuclides formed by thorium 232 and uranium 238 absorbing neutrons respectively.

After Villa captain Strian Petrov announced that he had hung up his boots because of acute leukemia, his team doctor in Bulgaria broke the news to The Sun yesterday, saying that the real reason for Petrov's illness was the Chernobyl nuclear accident!
1On April 26th, 986, the Chernobyl nuclear power plant in Ukraine exploded, and a large amount of high-radiation materials were thrown out and scattered by the wind, which seriously affected the countries around Ukraine. Sofia, the capital of Bulgaria, is only 1046 km away from Chernobyl, so the country has become one of the most polluted countries.
Petrov was born in Montana in northern Bulgaria. He was only 6 years old when the Chernobyl accident happened. "At that time, the nuclear radiation index in the area where his home was located had exceeded the normal value 1000 to 1300 times."
Dr. Mikhail Ilief, who has been the team doctor of the Bulgarian national team for 20 years, said in an interview with The Sun a few days ago that Petrov probably suffered from acute leukemia because of high-intensity radiation or eating contaminated food.
