Nuclear powered satellite

Japanese: 原子力衛星 - げんしりょくえいせい(英語表記)nuclear powered satellite
Nuclear powered satellite
These are nuclear reactor satellites equipped with small nuclear reactors and satellites that use nuclear batteries. Nuclear batteries use the radiation energy of plutonium 238. Since 1962, the Soviet Union has launched more than 30 satellites, either the Romashka type with a thermal output of 40 kW or the Topaz type with a thermal output of 130-150 kW, which use a thermocouple inside the reactor to generate electricity. The United States has launched 22 nuclear battery satellites since the 1960s. The nuclear reactor satellite SNAP-10A (thermal output 34 kW) was launched in 1965. Because cooling is difficult in space, the output of satellite reactors up to that point was around 5 kW, but in the 1980s, the United States developed the SP-100 nuclear reactor with an electrical output of 100 kW as part of the SDI project.
