What is fission explain with example?
many single celled organisms like protozoa and bacteria just splits into 2 identical halves during cell division leading to the creation of new organisms. this is called fission. fission is of two types : binary fission – eg: amoeba, paramecium , multiple fission – eg: plasmodium.
Where is fission used?
Uranium and plutonium are most commonly used for fission reactions in nuclear power reactors because they are easy to initiate and control. The energy released by fission in these reactors heats water into steam. The steam is used to spin a turbine to produce carbon-free electricity.
Is the sun fission?
Fusion is what powers the sun. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of energy.
What are 3 advantages of nuclear power?
What are the advantages of nuclear energy?
- One of the most low-carbon energy sources.
- It also has one of the smallest carbon footprints.
- It’s one of the answers to the energy gap.
- It is essential to our response to climate change and greenhouse gas emissions.
- Reliable and cost-effective.
Is nuclear energy safe?
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.
Is nuclear energy expensive?
Nuclear power plants are expensive to build but relatively cheap to run. In many places, nuclear energy is competitive with fossil fuels as a means of electricity generation. Waste disposal and decommissioning costs are usually fully included in the operating costs.
What companies use nuclear energy?

The United States
How many countries use nuclear power?
Nuclear power currently provides about 11% of the world’s electricity, with 12 countries using nuclear power for at least 30% of their national electricity generation. As of today, there are 449 operational nuclear power reactors in 30 countries, with 56 others under construction in 15 countries.
Why nuclear energy is not good?
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 India a nuclear power country?
Last Updated: November, 2019. India possesses both nuclear weapons and extensive nuclear fuel cycle capabilities. India tested its first nuclear device in May 1974, and remains outside both the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) and the Comprehensive Nuclear Test Ban Treaty (CTBT).
