The term 'KIND OF POWER PLANT' can be answered with the 7-letter word 'NUCLEAR'. NUCLEAR power plants are a type of power plant that use NUCLEAR fission to generate electricity. NUCLEAR fission is the process of splitting atoms to release energy, which is then used to heat water and create steam. The steam is then used to turn turbines, which generate electricity. NUCLEAR power plants are one of the most efficient sources of energy, but they also come with a number of safety concerns due to the radioactive materials used in the process.
