A nuclear explosion cannot occur because the fuel is not compact enough to allow an uncontrolled chain reaction. The MIT reactor has a large amount of water and core structural materials that slow down neutrons before they reach other fissile atoms. There have been only two major accidents at nuclear power plants, and their impacts have been much less serious than previously feared. Nuclear energy is the safest source of energy we use anywhere in the world.
A nuclear power plant uses uranium fuel to produce steam to generate electricity. This process converts uranium into other radioactive materials. If an accident occurs at a nuclear power plant, heat and pressure build up and steam, along with radioactive materials, can be released. So can this type of nuclear catastrophe happen again? Yes.
As long as we try to harness the power of the atom, the odds will fall in favor of disaster. But should we stop trying to do it? Not. Harnessing the power of the atom and mitigating the risks of nuclear energy to the best of our ability is one of the ways to achieve a cleaner energy future. Nuclear reactors can operate for long periods of time without human interference, but they are not designed to do so.
In the event of a natural disaster or power outage, backup systems would activate to keep the reactor stable until the fuel runs out. However, if backup power is also compromised, the reactor would eventually heat up and explode or melt through the reactor chamber. Studies conducted by, for example, the World Health Organization have concluded that the health effects of nuclear accidents from radiation have been very small. In early March, when Russia began bombing Europe's largest nuclear power plant, Zaporizhzhia, concerns grew about a possible nuclear fusion.
These days, citizens have become very aware of waste pools and have questioned their presence in populated areas, yet environmental activists have long tried to keep nuclear waste in power plants, insisting that its disposal poses serious dangers. Last winter's “bomber shoe” tried to detonate not a nuclear device, but rather a relatively available and very dangerous chemical compound hidden in its shoes. This resulted in the melting of three reactors of the nuclear plant and the release of enormous amounts of radioactivity. In a reactor, neutrons collide with other atoms, dividing them and generating heat in a process known as nuclear fission.
The first is that senior officials had ordered engineers to turn off security systems before investigating a power outage late at night. Russian troops captured the Chernobyl nuclear power plant at the beginning of the invasion and have now taken control of the Zaporizhzhia nuclear power plant, the largest in Europe. As a result, three cores largely melted over the next three days and there were several hydrogen explosions, as well as the release of nuclear material into the environment. The fire was extinguished and the nuclear plant is still under Russian forces and Ukrainian personnel keep the installation online and prevent the disaster.
Ukraine has 15 active nuclear reactors spread across the country and four dismantled in Chernobyl. Should the Zaporizhzhia nuclear power plant melt, the radiation would travel with the winds. It is not a nuclear explosion, but a steam explosion, caused by the enormous build-up of pressure inside the core. It was one of the largest nuclear power plants of its time and had the best engineers working to maintain it.
Even in the worst case scenario, a rupture of the reactor vessel would not entail any nuclear explosion, only a limited dispersion of radioactive materials. .
