1/7/2024 0 Comments Nuclear fission power plantMany people are familiar with the way a nuclear power plant works on Earth: a reactor heats up water from the heat generated by fission in fuel elements (rods, bundles, or pellets, usually), which then goes through a steam generator. ![]() So how is nuclear electricity generated in space? When these designs were first flown, photovoltaic panels were not nearly as efficient as they are today, so they weren’t considered a practical option, or the altitude of the satellite was so low that the air resistance on the panels would cause it to deorbit too soon to be useful. Radar is a notorious power hog, since resolution and power supply are directly proportional to each other. In the case of the US it was an experimental version of the Agena spacecraft and for the USSR and Russia, it was used for RORSATs (Radar Ocean Reconnaissance SATellites). All of these systems were designed to provide electrical power for a satellite. The US has flown one nuclear reactor (SNAP-10a) and the USSR and Russia have flown over thirty, using two different designs. Most people that have looked into in-space nuclear power know that using a nuclear reactor for electrical power is nothing new. This does not directly using the heat of the reactor like in a nuclear thermal rocket. Let’s look at the most popular way to use nuclear power in space.

Scientists ordinarily performed this task by blasting a large isotope with a second, smaller one - usually a neutron. In the 1930s, scientists determined that some nuclear reactions can be launched and regulated. The quantity of energy discharged during nuclear fission is millions of times more effective per mass than that of coal, assuming that only 0.1 percent of the original nuclei is transformed to energy. The fission of heavy particles is extremely exothermic than burning coal, releasing about 200 million eV. Nuclear Fission BasicsĪs mentioned before, fission is the splitting of a nucleus that delivers free neutrons and lighter nuclei. France produces over 75% of its electricity with nuclear power, while the US has 104 running reactors giving 20% of its electricity. ![]() In 2019 nuclear plants provided 2657 TWh of electricity, up from 2563 TWh in 2018. According to the World Nuclear Association, about 50 more reactors are under development, equivalent to around 15% of current capacity. Have you ever been interested in Guest Posting on Linquip?

Global warming has caused nuclear power as a viable and attractive energy alternative to fossil fuels. ![]() Hundreds of nuclear fission power plants worldwide attest that controlled fission is possible and economical. Controlled fission is a fact whereas controlled fusion is a dream that may be reached in the future. Nuclear Fission Equation – Nuclear fission is a reaction in which a nucleus is split.
