The number of neutrons existing in the critical core of the reactor must be steady or increasing, if it is decreasing the reaction will reduce and eventually stop. When a nucleus fissions (ie one of U-235) roughly 2.5 neutrons are produced, on average. Some of these are absorbed by the moderator and other incore materials, and some are lost at the core boundaries, but if for every nucleus that is fissioned, one neutron is then absorbed into another U-235 nucleus causing another fission, then the process will continue at a steady rate and we can call that a chain reaction. If there is a surplus of neutrons the population will increase and this could go on exponentially increasing, but this is contolled by the neutron absorbing control rods so that the neutron flux, or reactor power, is maintained at a steady level, for normal steady operation. In order for a nuclear chain reaction to take place, each nucleus must produce an average of one neutron that causes fission of another nucleus.
a long time, high temperature, and high density. If you need this for quest, the answer is "ALL OF THESE"
In a chain reaction, neutrons released during the splitting of an initial nucleus trigger a series of nuclear fissions.
bombardment with neutrons
Radioactive material
The excess energy is transferred to the particles as kinetic energy.
air pollution and hazardous wastes
Energy is formed and released following destruction of mass, E=mc2
Nuclear fission and reaction, intense heat.

SONE stands for Supporters Of Nuclear Energy. They are an organization that want to promote nuclear energy as not only an acceptable means of energy production, but a necessary one in order to face the future energy demands of the world. They feel nuclear energy would help developed countries to keep a sustainable economy.

Uranium is important in nuclear energy.

nuclear energy
Uranium is a radioactive substance. Nuclear power production is carried out by the energy supplied by nuclear reactors. Nuclear reactors control the energy emission by nuclear fission reaction in radioactive substance when bombarded by neutrons.
In the future the uses remain the same: production of electrical and thermal energy and nuclear weapons.
For electricity production, just under 20 percent
Only electricity production
The same as it is used now, for electricity production, plus nuclear weapons
Bcoz production of nuclear energy form harmful radioactive elements.
