Nuclear reactors are, fundamentally, large kettles, which are used to heat water to produce enormous amounts of low-carbon electricity. They come in different sizes and shapes, and can be powered by a variety of different fuels.(从根本上说,核反应堆是一个大水壶,用来加热水,产生大量的低碳电力。
The fuels for reactors are usually radioactive isotopes of uranium and plutonium. When these materials undergo fission, they break down into smaller elements and release energy and subatomic particles. Importantly, neutrons released by fission are used to generate the fission of additional atoms and ...

These are also known as CANDU type reactors. These reactors signify about 12% of the nuclear reactors globally. These are mainly used at all Canadian nuclear stations. These reactors use heavy water like both coolant & moderator. As a fuel, it uses natural uranium because, in a pressurized w...
With government regulators looking over their shoulders, engineers have spent a lot of time over the years designing reactors for optimal safety -- not just so they work properly, but so there are backup safety measures in place when something breaks down. As a result, year in and year out...

How do nuclear reactors start up? A neutron collides with a Uranium-235 atom. This extra neutron creates unstable Uranium-236 isotopes, which split almost instantly. This splitting produces heat, which is converted into energy for power, and it produces two neutrons which continue the process, ...
Have you ever wondered how a nuclear power station works? This lively book will answer that question. It’ll take you on a journey from the science behind nuclear reactors, through their start-up, operation and shutdown. Along the way it covers a bit of the engineering, reactor history, ...
Nuclear power stations and reactors operational around the world: listed and mapped: Where are all the world's nuclear power plants? What type of reactor do they use? When were they first opened? This March 2011 article from The Guardian presents a list of all the world's (non-scientific)...
"The U.S. government is pouring billions of dollars into their development and demonstration in the anticipation that they will work, be less expensive than large reactors, and provide the U.S. with a larger market for their export," Luongo told CNBC. "We'll see where we are by 2027...
