Is nuclear power a safe energy source?

Nuclear energy is a dream, which is why more and more countries are and should be using this energy source. We know its benefits – an affordable, available and reliable source of electricity that doesn’t generate greenhouse gases. One uranium pellet, can deliver over 17 MBTU of heat energy, which is equivalent to 1780lbs of coal, 17,000 cubic meters of natural gas, or 149 gallons of oil. In a different light, nuclear power generation is unique in how the amount of energy that is contained in a relatively small amount of volume. Burning fossil fuels for energy is dangerous to our environment for many reasons.
These include the ash, air pollution, ecosystem destruction from mining, water pollution, and etcetera. Nuclear energy doesn’t cause any type of greenhouse gases when it is running correctly. Also it causes a smaller effect on ecosystems when the uranium is mined because there is a smaller necessity for it. Uranium also heats water longer, about a few months, which is more sustainable than the short-term burning of fossil fuels, which usually lasts about a half hour.
Even though there are positive factors to nuclear energy, there are also some cons. Once certain fuels are used up it’s not a problem anymore, but in the case of nuclear energy, that is not the case. Since the fuel is both radioactive and fissionable is still concern about how the waste should be handled. Most nuclear waste remains radioactive for thousands of years. Human exposure to radiation can happen through nuclear power plant meltdowns as well as mistakes in the storage of nuclear waste.
Once radioactive contamination is started, there is a variety of different ways that it can contaminate the human body. The largest concern for safety will always be a major impediment in the progress of promoting nuclear power plants. The worst-case scenario for any nuclear power plant is the risk of a meltdown, which has proven to be very deadly in past disasters. A meltdown can be caused from a variety of human errors along with a variety of mechanical failures. Which proves: nuclear power can end catastrophic if not correctly monitored. Nuclear power can also end in a catastrophic end with the threat and chance of a terrorist attack.
Also nuclear power isn’t renewable. Renewable sources are a much better way to make energy for our planet because they are more sustainable and they can be used over and over again without causing much of a problem to ecosystems. Renewable energy sources, including wind, solar, geothermal, biomass, and water power. Some renewable energy resources, such as water, may cause ecosystems to be destroyed or changed. This would be due to dams being built that will destroy surrounding areas’ ecosystems and destroying the biodiversity of the water’s ecosystem.
