Claim: Next generation thorium reactors would be safer than current reactors. True but misleading. Nuclear energy is already very safe, and Yang is correct about that. The current US nuclear fleet generates about 20 percent of all electricity in the United States and has an excellent safety record—despite accidents such as Three Mile …

The state of nuclear energy today. Around the world, 440 nuclear reactors currently provide over 10 percent of global electricity. In the U.S., nuclear power plants have generated almost 20 percent of electricity for the last 20 years. Indian Point near New York City will shut down by 2021. Photo: Tony Fischer.

Thorium is able to "breed" U-233. It's the ability to separate the U-233 from the thorium that sets it apart from U-235 and U-238. We end up with a vast amount of waste from today's reactors that needs to be stored safely. The waste from a thorium reactor is radioactive for about 500 years compared to up to 10,000.

Check. Thorium reactors have efficiency levels as high as 98% compared to 5% for current uranium-based technologies, placing them well above fossil fuel and renewables systems in this area. The same analysis points out that pound for pound, thorium produces twice as much energy as uranium fission processes.

The advantage is one of the key properties of thorium reactors, as the vast amount of nuclear waste created by power plants can lead to high radiation and raise temperature levels.It also avoids a need to have a huge storage facility. Besides, the radioactivity levels of thorium waste are found to fall in a much shorter period than in …

Thorium reactors, some say, can provide limitless energy; with a fuel that's cheap, safe, and abundant; using reactors that can't melt down, can't be used for nuclear weapons production, and produce almost no appreciable waste. Such a system would seem to be a virtual miracle. So today we're going to examine these claims, and see if we can …

There are several ways thorium could be applied to energy production. One way under investigation now is to use solid thorium/uranium-232 fuel in a conventional water-cooled reactor, similar to modern uranium-based power plants. In fact, more than 20 reactors world-wide have been operated with fuel made of thorium and uranium-233.

Thorium reactors require an initial "seed" of U-233 to start the chain reaction to generate energy. China, whose thorium ambitions have expanded to include development of aircraft carriers, has little if any U-233. However, it has plenty of thorium, which is a byproduct of rare-earth mining on which China enjoys an uncontested monopoly.
