- It also has one of the smallest carbon footprints.
- It’s one of the answers to the energy gap.
- It’s essential to our response to climate change and greenhouse gas emissions.
- Reliable and cost-effective.
What are the disadvantages of nuclear energy Class 10?
Disadvantages of using nuclear energy are: Radioactive waste that results from nuclear power plants and nuclear reactions are a big threat to the environment. It involves huge investment and is not economical. Requires skilled labourers to construct, maintain and monitor the nuclear plant.

- Reliable. ...
- Zero carbon emissions. ...
- Promising future energy supply. ...
- High energy density. ...
- Environmental impact. ...
- Water intensive. ...
- Risk of nuclear accidents.
Why nuclear energy is bad?
Nuclear energy has no place in a safe, clean, sustainable future. Nuclear energy is both expensive and dangerous , and just because nuclear pollution is invisible doesn’t mean it’s clean. ... New nuclear plants are more expensive and take longer to build than renewable energy sources like wind or solar.
Is nuclear energy the best?
Nuclear power releases less radiation into the environment than any other major energy source. Second, nuclear power plants operate at much higher capacity factors than renewable energy sources or fossil fuels. ... Nuclear is a clear winner on reliability .
What is the biggest problem with nuclear energy?
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes . These materials can remain radioactive and dangerous to human health for thousands of years.
Is nuclear energy pros and cons?
| Pros of nuclear Cons of nuclear | Carbon-free electricity Uranium is technically non-renewable | Small land footprint Very high upfront costs | Reliable baseload electricity source Nuclear waste |

How safe is nuclear energy?
The evidence over six decades shows that nuclear power is a safe means of generating electricity . The risk of accidents in nuclear power plants is low and declining. The consequences of an accident or terrorist attack are minimal compared with other commonly accepted risks.
Why is nuclear energy cheap?
Despite some recent enthusiasm for smaller plant designs, evidence shows that nuclear plants with higher output produce cheaper electricity than ones with lower output . This is mostly because the additional workers required to produce power from bigger reactors are outweighed by the higher output.
What is the main use of nuclear energy?
Nuclear energy, which uses radioactive materials , has a variety of important uses in electricity generation, medicine, industry, agriculture, as well as in our homes.
Do we need nuclear energy?
Nuclear advocates claim nuclear is still needed because renewables are intermittent and need natural gas for backup. However, nuclear itself never matches power demand so it needs backup. ... Today, in fact, batteries are beating natural gas for wind and solar backup needs throughout the world.
Is nuclear energy renewable?
Nuclear energy is usually considered another non-renewable energy source . Although nuclear energy itself is a renewable energy source, the material used in nuclear power plants is not. ... Uranium is a non-renewable resource. Nuclear energy is a popular way of generating electricity around the world.
What are the limitations of nuclear energy?
Because nuclear power stations generate such a huge amount of electricity , when a nuclear power station goes offline it puts huge pressure on the grid. Even worse, nuclear power stations are often built using the same design and a problem identified at one could require all similar stations to be shut down for safety.
What are the advantages of nuclear Class 10?
A large amount of energy is produced per unit mass . It does not produce smoke. It is a clean energy. Fission of one atom of uranium produces 10 million times the energy released by burning of one atom of carbon.
