In this video Paul Andersen explains how nuclear energy is released during fission of radioactive uranium. Light water reactors, nuclear waste, and nuclear accidents are also discussed along with the future of nuclear energy.

Nuclear weapons are some of the most powerful tools of destruction on Earth, and the full scope of a nuclear detonation is almost unimaginable. However, there is a scientifically supported plan of action that could save thousands of...

The face of nuclear terror has changed since the Cold War, but disaster-medicine expert Irwin Redlener reminds us the threat is still real. He looks at some of history's farcical countermeasures and offers practical advice on how to...

Nuclear power is one of the safest, cleanest forms of energy -- yet to most people, it might not feel that way. Why is that? Isabelle Boemeke, the world's first nuclear energy influencer and creator of the social media persona Isodope,...

In a nuclear explosion, how close you are impacts your chance of survival. But who you are also has more influence than you might think. If everyone on Earth were equidistant from the bomb, here's the last person...

Our ability to mine great amounts of energy from uranium nuclei has led some to bill nuclear power as a plentiful, utopian source of electricity. But rather than dominate the global electricity market, nuclear power has declined from a...

We're not in a clean energy revolution; we're in a clean energy crisis, says climate policy expert Michael Shellenberger. His surprising solution: nuclear. In this passionate talk, he explains why it's time to overcome longstanding fears...

There are more than 10,000 nuclear weapons in existence today, each one capable of causing immense destruction. Why don't we talk about this threat as much as some other major issues? In this practical talk, nuclear security expert Emma...

Nuclear power: the energy crisis has even die-hard environmentalists reconsidering it. In this first-ever TED debate, Stewart Brand and Mark Z. Jacobson square off over the pros and cons. A discussion that'll make you think -- and might...

Kirk Sorensen shows us the liquid fuel thorium reactor -- a way to produce energy that is safer, cleaner and more efficient than current nuclear power.

Taylor Wilson was 14 when he built a nuclear fusion reactor in his parents' garage. Now 19, he returns to the TED stage to present a new take on an old topic: fission. Wilson, who has won backing to create a company to realize his...

Before the Orion of today, the Orion of the 1950s was propelled by nuclear bombs exploding behind it.

Fusion power is supposed to save us from fossil fuels, so when is nuclear fusion going to be a viable option and why has it been so elusive?

Hidden beneath Greenland’s ice and powered by a nuclear reactor, Camp Century made for an interesting US military base. But life under the ice came with unique struggles; and although it wasn’t mainly constructed for science, the base...

Nuclear war is a terrifying existential threat, but we shouldn't only fear the blasts because the ensuing smoke is the real killer.

Continuing our look at Nuclear Chemistry, Hank takes this episode to talk about Fusion and Fission. What they mean, how they work, their positives, negatives, and dangers. Plus, E=mc2, Mass Defect, and Applications of Fission and...

Carl Sagan predicted some amazing things including the aftermath of nuclear war.

Nuclear power may not be as bad as you think. If we used Thorium instead of Uranium, we could greatly decrease dangerous radioactive by-products. There is enough Thorium in the world to meet all our energy needs...

Nuclear fission is the process used in nuclear power plants, which creates radioactive nuclear waste that is hazardous to humans. Discover how this nuclear waste is disposed of and stored. Earth Science - Earth's Resources - Learning...

Examine the aftermath of the Cuban Missile Crisis and its impact on global nuclear policies. Learn how the United States and the Soviet Union removed missiles from Cuba and established a hotline for direct communication. Understand the...

We aren’t using nuclear fusion to generate power yet because it is incredibly difficult to sustain a fusion reaction. The energy requirements are very high, and it is hard to find materials that can withstand such high temperatures. For...

This video explains the process of nuclear fission and how it powers nuclear reactors to produce electricity. Learn how uranium atoms are split to create heat, which then drives steam turbines to generate energy, all while avoiding...
