1 00:00:01,296 --> 00:00:04,561 The process of creating electricity using nuclear power 2 00:00:04,599 --> 00:00:08,180 begins with splitting of uranium atoms in the reactor. 3 00:00:08,505 --> 00:00:11,428 This process called fission, produces heat. 4 00:00:11,724 --> 00:00:13,731 In a pressurized water reactor, 5 00:00:13,760 --> 00:00:16,245 the heat from the water surrounding the nuclear fuel 6 00:00:16,298 --> 00:00:19,000 is kept under pressure to prevent it from boiling. 7 00:00:20,169 --> 00:00:23,834 The hot water is piped from the reactor vessel to a steam generator, 8 00:00:23,877 --> 00:00:28,877 where it transfers its heat to boil water and make steam in a second system. 9 00:00:29,500 --> 00:00:31,444 After transferring its energy, 10 00:00:31,499 --> 00:00:34,796 the water is pumped back to the reactor vessel to be reused. 11 00:00:36,400 --> 00:00:39,213 The non-radioactive steam from the steam generator 12 00:00:39,258 --> 00:00:43,230 spins turbines that drive the generator to produce electricity. 13 00:00:44,890 --> 00:00:49,018 After the steam is used in the turbines it is drawn into a condenser, 14 00:00:49,078 --> 00:00:51,474 where it is cooled and condensed back in the water 15 00:00:51,515 --> 00:00:55,274 and pumped back to the steam generator to be heated and reused.
