What are the pros and cons of fusion power?
Pros
- Clean energy.
- Virtually limitless fuel available.
- No chain reaction. Easier to control or stop than fission.
- Little or no nuclear waste. Core remains radioactive for only 100 years.
- Very low fuel cost.
Which of the following is a disadvantage of a nuclear fusion over nuclear fission?
Nuclear fission power plants have the disadvantage of generating unstable nuclei; some of these are radioactive for millions of years. Fusion on the other hand does not create any long-lived radioactive nuclear waste. A fusion reactor produces helium, which is an inert gas.
Is nuclear fusion bad for the environment?
Fusion is among the most environmentally friendly sources of energy. There are no CO2 or other harmful atmospheric emissions from the fusion process, which means that fusion does not contribute to greenhouse gas emissions or global warming.
Why is nuclear fusion so difficult?
Without the electrons, atoms have a positive charge and repel. This means that you have to have super high atomic energies to get these things to have nuclear fusion. High energy particles are the problem. This is why fusion is difficult and fission is relatively simple (but still actually difficult).
Why do we still need nuclear power?
Safer and Cheaper. The tsunami that hit Japan in March marked the first time that an external event led to a major release of radioactivity from a nuclear power plant.
What are the negatives of nuclear energy?
Negative effects of Nuclear Energy Difficult to manage: Nuclear energy can have a great negative impact on the environment. Disposal of radioactive waste: Nuclear energy may be a great source of energy but the tons of waste produced after the usage of this energy is liable to add to the high temperature and transmitting harmful radiations.
Why is energy released in nuclear fusion?
Fusion is the mechanism by which active stars are powered, releasing vast amounts of energy. The basis of the energy produced in the fusion of light elements is due to the interplay of two competing forces: the nuclear force, which draws protons and neutrons together and the Coulomb force, which repels each other by triggering protons.
What is Fusion vs fission?
Fission is the splitting of the nucleus, whereas fusion is the joining of two nuclei. Fission requires considerably less energy than fusion to carry out, but also releases less energy than fusion. Both are used in nuclear weaponry. Fission refers to splitting or breaking apart.
