Total energy storage of nuclear fission elements in the world

How much energy does a nuclear fission release?

In general, nuclear fission results in the release of enormous quantities of energy. The amount of energy depends strongly on the nucleus to be fissioned and depends strongly on an incident neutron’s kinetic energy. The total energy released in a reactor is about 210 MeV per 235 U fission, distributed as shown in the table.

Can nuclear fission be stored long-term?

The byproducts of nuclear fission are highly radioactive and must be secured away from people for hundreds of thousands of years. There are currently no proven long-term solutions for storage of this radioactive waste.

How much radioactivity is released in a fission?

This radioactivity (by definition!) decreases with time. The total binding energy released in fission of an atomic nucleus varies with the precise break up, but averages about 200 MeV* for U-235 or 3.2 x 10 -11 joule. This is about 82 TJ/kg. That from U-233 is about the same, and that from Pu-239 is about 210 MeV* per fission.

How much energy does a fission fragment produce?

In most cases, the resultant fission fragments have masses that vary widely, but the most probable pair of fission fragments for the The largest part of the energy produced during fission (about 80 % or about 170 MeV or about 27 picojoules) appears as kinetic energy of the fission fragments.

How does nuclear fission occur?

Nuclear fission is the process of splitting a large atom into two smaller atoms. This process releases a significant amount of heat, which is then used to boil water, make steam, turn a turbine and generator, and ultimately produce electricity. Most nuclear power plants today use enriched uranium 235 as fuel, providing non-renewable, carbon-free, and 24/7 electricity.

What is a fission product?

The fission products are only four percent of the total volume of spent nuclear fuel, and represent the nuclear waste, which is stored long-term until it loses its radioactivity.
