Topaz nuclear reactor for powering satellites
Numéro d’image : 11889048
| Satellite reactor. Topaz thermionic nuclear reactor used to power satellites and spacecraft. Thermionic reactors generate electricity by using heat to "boil" electrons from a cathode which then cross a short space to an anode. Nuclear reactors can provide a steady power over a long life. However,they are expensive,heavy,and can lead to environmental pollution if the spacecraft re- enters the atmosphere. First designed in 1958,Topaz reactors were used in Soviet Cosmos satellites. A development of the original design is scheduled for use in American spacecraft in the twenty-first century | |
