Nuclear Energy Pros & Cons: Is it Safe & Renewable?

Nowadays, nuclear energy is a hot topic all over the world.

In order to meet the population’s large-scale energy requirements, renewable energy sources such as solar and wind have not yet proven themselves to be viable alternatives.

It is critical that we investigate nuclear energy as a dependable energy source in order to meet the world’s constantly increasing energy demands.

Fission is the term used to describe the process by which nuclear energy is produced. A nuclear fission event occurs when the atom of a nucleus splits, releasing enormous amounts of energy in the process.

Atoms are continuously split in nuclear power plants, resulting in chain reactions that produce large amounts of sustainable energy over a long period of time. Nuclear power plants are used to generate electricity in the United States.

Nuclear energy, like all other energy sources, has its advantages and disadvantages. Nuclear energy is no exception.

The disposal of radioactive waste, the high up-front construction costs, and the general public’s safety are all important considerations that must be considered.

Let’s take a closer look at some of the major pros and cons of nuclear energy.

Advantages of Nuclear Energy (Pros)

After the meltdown at Three Mile Island in 1978 and the explosion at Chernobyl in 1986, the nuclear industry went into hibernation for nearly two decades.

A number of power plants were forced to shut down, and the construction of new power plants was put on hold as a result.

Since then, there has been a resurgence of interest. Energy demands are at an all-time high in this technological age, and nuclear energy had to be considered as a viable source of energy.

The benefits of nuclear energy are listed below, along with some of the arguments in favor of its revival.

Low Greenhouse Gas Emissions.

Nuclear power emits the least amount of greenhouse gases when compared to coal, natural gas, and other types of electric-generating plants.

Carbon dioxide and other greenhouse gases, which are known for depleting the Earth’s atmosphere, have long been a source of contention in the climate change debate. As a result, nuclear energy has once again been considered for use in the generation of electricity.

It is estimated that nuclear energy generates more clean-air energy than any other source, according to the Nuclear Energy Institute (NEI). It accounts for 62 percent of all emission-free electricity generated in the United States.

A common misconception about nuclear reactors, particularly those that employ large cooling towers, is that pollution is released in large quantities into the atmosphere. The massive clouds of vaporized water that you see rising from the smoke stacks are nothing more than that.

We have written an article discussing the actual causes of air pollution and their consequences, which can be found here – the third item on our list is the most intriguing.

High Power Output.

One of the most compelling arguments in favor of nuclear energy is the extremely high fuel-to-power output ratio that it provides. It has the capability to meet the needs of cities and industries with a single reactor, let alone multiple reactors.

A relatively small amount of uranium can be used to fuel a 1000 Megawatt electric plant, which can generate enough electricity to power a city of about half a million people with a relatively small amount of fuel.

Renewable energy sources, such as solar and wind, can only provide enough electricity to meet the needs of a single household or office. In order to meet large-scale energy demands, particularly in the manufacturing sector, they do not yet have the capacity that nuclear does.

Inexpensive Electricity.

Initial construction costs for nuclear power plants are high, as we will discuss further in the cons section. Having said that, once nuclear power is up and running, it produces electricity at a very low cost.

Electricity generated by nuclear reactors is significantly less expensive than electricity generated by natural gas, coal, or any other fossil fuel plant. Furthermore, uranium is a relatively inexpensive fuel source, and we have already discussed how little of it is required to generate massive amounts of energy.

The low operating costs far outweigh the high initial construction costs when all of this is taken into consideration, as well as the average lifecycle of 40-60 years.

Nuclear Energy Doesn’t Rely on Fossil Fuels.

The fact that nuclear energy does not rely on fossil fuels is perhaps the most significant advantage of the technology. This means that it is not affected by fluctuations in the price of oil and natural gas.

It also means that we will not be depleting the Earth’s supply of resources at nearly the same rate as we have in the past. Nuclear power uses significantly less fuel to produce a greater amount of energy than other sources.

With the current supply of uranium, it is estimated that we will have at least another 80 years before a shortage of the element arises, if not longer. There are also other forms of uranium that can be used if necessary, which could further extend the timeline. If alternative energy sources (such as nuclear fusion, the holy grail of energy) are required, there will be plenty of time to do so.

Economic Impact.

There are numerous economic benefits to be gained from nuclear power generation. Local communities are more often than not pro-nuclear because of the number of jobs and economic opportunities that a new nuclear power plant brings.

According to the Nuclear Energy Institute, a new nuclear plant generates between 400 and 700 permanent jobs, not to mention thousands of additional jobs during the construction phase. The majority of nuclear power plants have at least two reactors. Compared to a coal plant, which employs 90 people, and a natural gas plant, which employs 50 people, this is a significant increase.

The primary reason that local communities are ecstatic about nuclear plants is that each facility generates close to $500 million in sales of goods and services each year, according to industry estimates. There are more people working in plants, which means there are more people who need lunch and more people who have money to spend.

Disadvantages of Nuclear Energy (Cons)

Nuclear energy has a number of advantageous characteristics that are attracting the attention of more and more countries around the world. However, as with all energy sources, it has its drawbacks.

Many people are apprehensive about nuclear power as a result of the few, but extremely significant, accidents that have occurred over the course of history.

Furthermore, while nuclear energy produces little pollution to the environment, it is not without its own environmental consequences.

Consider some of the disadvantages of nuclear power in more detail now.

Back-end Environmental Impact.

The environmental impact of uranium as a fuel source is perhaps the most significant source of concern among nuclear energy supporters.

A typical nuclear power plant generates about 20 metric tons of spent nuclear fuel per year, according to the Nuclear Energy Institute. The problem is that this spent fuel is extremely radioactive and therefore potentially hazardous.

It is not a fuel source that can be disposed of in a landfill without causing concern. Heavily corrosive materials must be handled and stored with care (which is extremely expensive), and they require a significant amount of specially designed storage space.

It takes hundreds of years for spent nuclear fuel to decompose to the point where it is no longer a threat to public safety. For this reason alone, it becomes a problem that other forms of energy do not have to deal with at all.

Past History of Nuclear Accidents.

Originally, I listed these as numbers 1 and 2, but if I had the option, I would have listed them as numbers 1 and 1. In contrast to scientists in the nuclear industry, the general public is terrified of the possibility of a nuclear disaster.

Safety is a major concern in the nuclear industry these days, and with good reason: accidents can happen. Significant accidents are extremely rare in the modern era; however, the past must not be forgotten. And when they do occur, it causes a significant problem.

The Fukushima disaster in Japan in 2011 served as a timely reminder to the world’s population that nuclear power still has its drawbacks. However, even though the number of deaths was low, the environment continues to be a concern today.

Chernobyl is widely regarded as the worst nuclear accident in the history of the industry. It occurred on April 26, 1986. However, despite the fact that it occurred more than 30 years ago, the negative consequences are still felt today.

High Up-Front and End Stage Cost.

We’ve already talked about how nuclear power plants generate electricity at a low cost and with high efficiency while they’re in operation. Generally speaking, the advantages outweigh the disadvantages; however, the cost of new plants can be a significant deterrent for countries considering new plant construction.

Construction of a new plant can take anywhere from 5 to 10 years and cost billions of dollars, depending on the size of the facility. Much of that, and even more, is recouped over the course of the plant’s lifetime, but it’s understandable why some countries might be hesitant to pursue it.

Moreover, high fuel handling and decommissioning costs are not to be taken lightly on the back end. Nuclear energy, on the other hand, almost always pays off in the long run, if you can stomach it over time.

Target for Terrorism.

When most people hear the word “nuclear,” they immediately conjure up images of the nuclear bomb and the city of Hiroshima. While nuclear power generation is distinct from the production of weapons of mass destruction, it does pose a threat to national security if it is exposed to potentially dangerous individuals.

The uranium used to power nuclear power plants is of a different grade than the uranium used to make nuclear weapons; however, it is possible to synthesize weapons-grade uranium from it.

When nuclear technology falls into the wrong hands, it poses a threat to the majority of the free world. Despite the fact that security is tight and the likelihood of an event is low, it is something to consider that you do not necessarily have to be concerned about with other forms of energy.

Not a Renewable Fuel Source.

Lastly, but certainly not least, nuclear energy does not qualify as a renewable energy fuel.

The element uranium, contrary to popular belief, is in limited supply (although it is currently abundant). Despite the fact that it is not a fossil fuel, we still run the risk of running out at some point.

Solar and wind energy, for example, are both infinitely abundant sources of renewable energy. Uranium must be mined, synthesized, and then activated in order to be used as a source of energy, and this is a time-consuming and expensive process.

This alone is one of the primary reasons why people are attempting to make renewable energy sources acceptable for use in meeting our world’s energy needs.


When it comes to nuclear energy, the advantages far outweigh the disadvantages the vast majority of the time.

In addition to having extremely low operating costs and producing enough energy to meet demand, it also has a slew of other economic benefits that can’t be overlooked.

While accidents and the environmental impact of spent fuel must be taken into consideration, we simply do not have any better options for long-term mass energy production than nuclear power and nuclear power plants.

If more effective alternatives are discovered, the future of nuclear energy will have to be re-examined.

People with exceptional intelligence, such as Elon Musk, are working tirelessly to ensure that renewable energy sources (such as solar, wind, and geothermal) are included in the discussion about long-term sustainable power. New and exciting technology is introduced on a daily basis, and this trend is expected to continue.

For the time being, however, nuclear energy remains one of the only viable options for meeting the world’s growing energy demands.
