How does nuclear energy work?
At nuclear power plants, the heat to make the steam is created when uranium atoms split. Pressurized Water Reactors keep water under pressure so that it heats, but doesnt boil.

How can nuclear energy be used?
Nuclear energy can be used to create electricity, but it must first be released from an atom. In nuclear fission, atoms are split to release the energy. A power plant, is a series of machines that can control nuclear fission to make electricity.

What effects does nuclear energy have on the environment?
Nuclear power plants do not emit carbon dioxide, sulfur dioxide, or nitrogen oxides as part of the power generation process. However, fossil fuel emissions are combined with the uranium mining and uranium enrichment process.

Is nuclear energy accepted today? Why or why not?
There are over 435 commercial nuclear power reactors operable in 31 countries, with over 375,000 miles of total capacity. About 70 more reactors are under construction. Nuclear energy is being used even more than ever. It conducts energy for people. And it helps us live the lives we live, it helps power plants, radiation therapy, and many more.
