Two nuclear industry organizations provide a wealth of information about nuclear energy on their Web sites. The UK-based World Nuclear Association, a group composed mostly of nuclear power companies, offers detailed and comprehensive information about nuclear power generation and all aspects of the nuclear fuel cycle. The US-based Nuclear Energy Institute, another industry group, also provides information about nuclear power, as well as information on the medical and food-safety uses of nuclear energy.
