According to the power generation process of a nuclear power plant, the energy transfer and conversion process of nuclear power generation is: nuclear energy → internal water and steam energy → mechanical energy of the generator rotor → electrical energy therefore; The energy conversion of the ACD in the option is done during nuclear power generation.
So choose ACD.
A method of producing electricity using thermal energy released by nuclear fission in a nuclear reactor. It is very similar to thermal power generation, except that nuclear reactors and steam generators are used to replace thermal power boilers, and nuclear fission energy is used to replace thermal power. chemistry of fossil fuels. Except for boiling water reactors, other types of power reactors heat the coolantement through the reactor core, transfer heat to the water in the steam generator, and then form steam to drive the turbogenerator. In a boiling water reactor
The coolant is heated through the reactor core and transformed into supersaturated steam with a pressure of about 70 atmospheres. Once the steam and water are separated and dried, it directly drives the turbogenerator. /p>
Use of nuclear power generation The heat generated by the nuclear fission chain reaction of uranium fuel heats water to high temperature and high pressure, and uses the generated water to produce steam
rotate the steam turbine and drive the generator. The heat released by nuclear reactions is much greater than the energy released by burning fossil fuels (the difference is about a million times). In comparison, the volume of fuel required is welllower than that of thermal power plants. Uranium 235 used in nuclear power production is only 3% pure. 4%, and the rest is uranium 238 which cannot produce nuclear fission.
For example, a nuclear power plant uses 80 tons of nuclear fuel each year, and only 2 standard containers can transport it. If it were to be powered by coal, it would require 5.15 million tonnes and 20 tonne trucks to transport 705 cars per day. If natural gas is used, 1.43 million tons are required, which is equivalent to burning 10,000 barrels of domestic natural gas every day.
