The nuclear cycle is a complex loop of mining, research, international deals, refinement, and energy. In the past, a good deal of this energy was released in explosions in New Mexico, Semipalatinsk, the Algerian desert, et. al. Since most countries, excluding the US and China, have signed and ratified the Comprehensive Nuclear-Test-Ban Treaty, testing and development of nuclear weapons has decreased. The increasing output of nuclear fuel, however, can enter homes and businesses through electricity. If China has its way, it will be the leading producer of nuclear energy by 2040. Goals such as these, not just in China but in many other countries including India and South Korea have created a demand in nuclear fuels from countries like Canada, accustomed to supplying nuclear products, and also from new entries to the nuclear market like Tanzania. Furthermore, the material of nuclear cores once used for bombs are now being converted to work within nuclear reactors. In the rush to power our lives, it is important to consider security and toxicity issues.
