With four nuclear reactors, Hungary derives about 37 percent of its electricity from nuclear power. It brought its first reactor online in 1982. One reason Hungary supports nuclear is its price. In 2007, according to the World Nuclear Association, the price was below 5 cents per kilowatt hour. Another is diversification. The former Soviet satellite is heavily dependent on Russian natural gas deliveries.
