How is nuclear fission converted into usable energy?

Answer 1

Mass is converted to energy when nuclei rearrange themselves from a form with extra nuclear binding energy to a form with less nuclear binding energy. This is true whether the reaction is nuclear fusion, nuclear fission, or nuclear decay. This energy appears mostly as heat.

In nuclear power plants this energy must be converted to a usable form, usually electricity. Most plants use the heat to make steam (just as in fossil fueled plants) to turn turbines which turn generators. In small SNAP power plants (portable or used in spacecraft) the heat is used directly to generate electricity using thermocouples.

Answer 2

Mass is destroyed. E=MC squared, E being given in the form of radiation.

The radiation absorbed typically by water jacket, causes the water to heat, generate steam and drive a turbine.

Answer 3

In nuclear fission, atoms of fissionable material split after absorbing a neutron. The atom splits approximately into two equal pieces, and those two pieces, called fission fragments, recoil from the event. As the nuclear fuel is metal and is held in a metallic crystal matrix, when the fission fragments recoil, they can't get very far. But their tremendous kinetic energy will result in a large increase in the thermal energy of the metal at the site of the fission. Nuclear energy (a nuclear reaction) has been expressed as thermal energy, and it is the heat that we draw out of the fuel elements by passing coolant of some kind over them to carry away that heat.

Answer 4

The energy created from a nuclear chain reaction is distributed to the compound heavy water (2h20) in the form of thermal energy. The heavy water serves two purposes, to cool the reactor, and also to distribute the thermal energy. the heavy water is then piped to a steam turbine, where the heavy water filled pipes will boil regular water (h2o). the steam power turns the turbine, which will then generate electricity. The heavy water will then circulate back to the reactor, to continue cooling and transporting more thermal energy. the regular water is usually obtained from a near-by water source, and released in the form of steam. the electrical energy created form the turbine is stored in sent through the grid system.

Answer 5

The isotopes uranium-235 and uranium-233 are fissionable with thermal neutrons; the energy of the nuclear fission is converted in electricity or heat.
The fission energy is huge: 24 000 000 kWh for 1 kg uranium-235.

Answer 6

In a nuclear power plant? Gernerally the radioactive material is used to heat water, the water boils to create steam, then the steam pressure is used to drive turbines.

Answer 7

Nuclear reactors operate by producing a fission chain reaction in U235, which releases heat, which is used to raise steam to drive a turbine/generator set.

Answer 8

All current power reactors use the reaction heat to make steam and then the process is identical to conventional combustion power plants.
