how is this power used in space ?
Both fission and fusion appear promising for space propulsion applications, generating higher mission velocities with less reaction mass. This is due to the much higher energy density of nuclear reactions: some 7 orders of magnitude more energetic than the chemical reactions which power the current generation of rockets.
Nuclear power
Both fission and fusion appear promising for space propulsion applications, generating higher mission velocities with less reaction mass. This is due to the much higher energy density of nuclear reactions: some 7 orders of magnitude (10,000,000 times) more energetic than the chemical reactions which power the current generation of rockets.
where can the resource for nuclear energy be found It is produced by nuclear fission of uranium and plutonium. what is nuclear power ? It is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. which was the first nuclear reactor ? Chicago Pile-1 does this power produce any waste ? Yes, spent nuclear fuel is the waste generated. what are different types of waste ? Low-level radioactive waste, is one type of nuclear waste. It is found in the form of contaminated items like clothing, hand tools, water purifier resins, and the materials of which the reactor itself is built. what is nuclear fusion ? It is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. how is the waste disposed off ? There are no commercial scale purpose built underground high-level waste repositories in operation. Presently, waste is mainly stored at individual reactor sites and there are over 430 locations around the world where radioactive material continues to accumulate. the first nuclear reactor you mentioned above where is located ? Stagg Field what was  its significance ? The successful test of CP-1 not only proved that a nuclear reactor was feasible, it demonstrated that the "k" factor was larger than originally thought. It removed the objections to the use of air or water as a coolant rather than expensive helium. It also meant that there was greater latitude in the choice of materials for coolant pipes and control mechanisms. how was it developed ? In August 1941 Fermi began to plan the building of a sub-critical assembly to test with a smaller structure whether a larger one would work. The pile was built in September 1941 from graphite blocks and tinplate iron cans of uranium oxide. did it have any government support ? Yes, the "Einstein–Szilard" letter resulted in the establishment of research into nuclear fission by the U.S. government. regarding the energy above were there any accidents ? Yes, one of them was the Chernobyl accident in 1986. It caused approximately 50 deaths from direct and indirect effects, and some temporary serious injuries. what happened at this accident ? UNANSWERABLE the power you mentioned above is it a renewable energy ? Several studies suggest that it might be theoretically possible to cover a majority of world energy generation with new renewable sources. The "Intergovernmental Panel on Climate Change" has said that if governments were supportive, renewable energy supply could account for close to 80% of the world's energy use by 2050. what is the type of waste you mentioned above ? "Spent nuclear fuel", occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor.

Nuclear power [SEP] Use in space
Both fission and fusion appear promising for space propulsion applications, generating higher mission velocities with less reaction mass. This is due to the much higher energy density of nuclear reactions: some 7 orders of magnitude (10,000,000 times) more energetic than the chemical reactions which power the current generation of rockets. Radioactive decay has been used on a relatively small scale (few kW), mostly to power space missions and experiments by using radioisotope thermoelectric generators such as those developed at Idaho National Laboratory.
