At its birth, nuclear power was a closely guarded national enterprise, only accessible to the most prosperous nations. But over the last 50 years it has evolved into a robust international market with a global supply chain. Not only are more countries starting or considering new nuclear plants, a great many more countries are contributing to their construction.
According to data from the International Atomic Energy Agency (IAEA) 64 nuclear reactors are under construction around the world. Dozens more are in various stages of planning.
