Nuclear power pros and cons: Here we take a closer look at the benefits and drawbacks of the power source
Nuclear power is regarded as one of the prominent sources of energy in the world today but like any other it has a wide range of pros and cons.
As nuclear plants emit low greenhouse gas emissions, the energy is seen as environmentally friendly.
Using a nuclear fission reaction, the power plants produce high amount of electricity with uranium as fuel, making them a productive addition to any grid.
Here we break down the main benefits and drawbacks of the power source.
Nuclear power pros and cons: Advantages
Low harmful emissions
Electricity produced from nuclear power plant emits fewer greenhouse gas emissions compared to those released by coal power plants and other traditional power generation sources.
Nuclear energy generation does not lead to releases of methane and carbon dioxide, which are greenhouse gases responsible for global warming.
Taking this into account, the environmental damage caused by nuclear energy sources is considered minimal.
When compared to renewable sources of energy such as solar and wind, power generation from nuclear power plants is more reliable.
While electricity production in the case of renewable sources depends on climatic conditions, there is no such hurdle in nuclear energy.
Nuclear power units can produce power continuously for several months without any interruption.
In addition, with uranium reserves expected to last for more than 70 years from now, nuclear energy offers higher reliability compared to other energy sources.
Low operational expenses
Though setting up nuclear power plants requires huge initial investment, the costs associated with operating them thereafter are low.
The fuel costs of a nuclear power plants are also low and the electricity produced from them is also not expensive.
Considering their typical lifetime, which is about 40-60 years, the overall expenses involved in producing power from nuclear power plants are comparatively minimal.
Moreover, fluctuations in uranium price will not have much impact on the costs to generate electricity from a nuclear power plant.
High energy density
Nuclear energy sources have higher density than fossil fuels and release massive amounts of energy.
Due to this, nuclear power plants require low quantities of fuel but produce enormous amounts of power.
The energy produced by a nuclear fission process is one million-times more than that of a thermal power plant.
Nuclear power pros and cons: Disadvantages
One of the major negatives of nuclear energy is the impact of uranium on the environment.
While transportation of nuclear fuel to a power plant can cause pollution, the process involved in mining and refining uranium is also a concern.
Also, the used uranium can pose risks, as the fuel is radioactive.
Fuel waste disposal concerns
The vast amount of nuclear waste created by power plants can lead to high radiation and raise temperature levels.
The transmission of this radiation can cause a potential damage to the surrounding atmosphere.
The cost of managing the nuclear waste is also high.
Limited uranium reserves
Similar to fossil fuels, uranium reserves are limited and present in few nations.
The processes carried out to mine and refine uranium involve huge costs.
Transporting refined uranium for use in nuclear power plants will also need huge spending.
As large amounts of waste are created during the refinement of uranium, any mishandling of the processes can affect the environment and pose health risks to human beings.
Long construction time-frame
The construction of nuclear power plants usually take several years to complete as they require large infrastructure.
The difficulties in producing power from a nuclear plant in a short period of time makes them less favourable compared to building electricity plants that run on traditional sources.
Also, massive investments are required to build a nuclear power plant, as costs involved in installing radiation containment systems are high.
