Which is not a disadvantage of nuclear energy?

Which is NOT a disadvantage of nuclear energy? Air pollution occurs while the nuclear plant is active. Nuclear power plants are very difficult to build. Acquiring nuclear fuel requires mining.

Which of the following is a disadvantage of using nuclear energy as a source of electricity quizlet?

Nuclear energy produces no greenhouse gases, does not contribute to acid deposition, and is highly concentrated. Disadvantages of nuclear energy include the high cost of building a power plant and safety concerns about the operation of the plant and disposal of spent fuel rods.

Is nuclear energy good for the environment?

Nuclear is a zero-emission clean energy source. … According to the Nuclear Energy Institute (NEI), the United States avoided more than 476 million metric tons of carbon dioxide emissions in 2019. That’s the equivalent of removing 100 million cars from the road and more than all other clean energy sources combined.

Does nuclear energy cause global warming?

Nuclear power plants produce no greenhouse gas emissions during operation, and over the course of its life-cycle, nuclear produces about the same amount of carbon dioxide-equivalent emissions per unit of electricity as wind, and one-third of the emissions per unit of electricity when compared with solar.

Why should we not use nuclear energy?

National security. Nuclear power plants are a potential target for terrorist operations. An attack could cause major explosions, putting population centers at risk, as well as ejecting dangerous radioactive material into the atmosphere and surrounding region.

What is environment and environmental pollution?

Environmental pollution is defined as “the contamination of the physical and biological components of the earth/atmosphere system to such an extent that normal environmental processes are adversely affected.

What is nuclear pollution causes and effects?

Any adverse impact caused by radioactive contaminants or radiation to the atmosphere is called nuclear contamination. There are various causes of nuclear pollution. Nuclear power plants are without a doubt are the main source of causing pollution. This kind of emissions can also be caused by radiation emission.

What are the effects of radiation on the environment?

Even sunlight, the most essential radiation of all, can be harmful in excessive amounts. Most public attention is given to the category of radiation known as “ionizing radiation.” This radiation can disrupt atoms, creating positive ions and negative electrons, and cause biological harm.

Why is nuclear waste so polluting?

At present, radioactive waste is generated in Canada from a variety of activities, including: uranium mining, milling, refining and conversion; nuclear fuel fabrication; nuclear reactor operations; nuclear research; facility decommissioning; and the remediation of contaminated sites.

How does nuclear energy affect the economy?

The nuclear industry supports nearly half a million jobs in the United States and contributes an estimated $60 billion to the U.S. gross domestic product each year. U.S. nuclear plants can employ up to 700 workers with salaries that are 30% higher than the local average.

What are the cons of nuclear fusion?

It is extremely difficult to achieve. In stars, strong gravitational forces and high temperatures naturally create a fusion environment. …
It produces radioactive waste. …
More research and brainpower is needed to solve its issues. …
Its practical energy returns are still quite unreachable.

What are the advantages and disadvantages of nuclear energy Class 10?

Advantages of Nuclear Energy

It produces a large amount of energy for a small amount of fuel.
Once we put the nuclear fuel in the reactor, it can produce energy for 2 or 3 years continuously, we do not need to put fuel again and again.
No greenhouse gas is emitted while producing Nuclear Energy.
