Nuclear Fission Chain Reaction Equation

Nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions thus leading to the possibility of a self propagating series of these reactions.

In a nuclear reactor a neutron is absorbed into a nucleus typically uranium 235. This chain reaction depends on the release of more neutrons than were used during the nuclear reaction.

If you were to write the equation for the nuclear fission of u 238 the more abundant isotope of uranium youd use one neutron and only get one back out. The fission process often produces free neutrons and photons in the form of gamma rays and releases a large amount of energyin nuclear physics nuclear fission is either a nuclear reaction or a radioactive decay processthe case of decay process is called spontaneous fission. If an least one neutron from u 235 fission strikes another nucleus and causes it to fission then the chain reaction will continue.

In a typical nuclear fission reaction more than one neutron is released by each dividing nucleus. It was pointed out in the preceding articles that the neutron induced fission reaction is the reaction in which the incident neutron enters the heavy target nucleus fissionable nucleus forming a compound nucleus that is excited to such a high energy level e excitation e critical that the nucleus splits into two large fission fragments. Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts lighter nuclei.

If the reaction will sustain itself it is said to be critical and the mass of u 235 required to produced the critical condition is said to be a critical massa critical chain reaction can be achieved at low concentrations of u 235 if the neutrons from. Nuclear fission nuclear fission fission chain reactions and their control. For u 235 on average 25 neutrons are emitted starting on average two more fission reactions.

Below is a simple fission process. The nuclear chain reaction releases several million times more energy per reaction than any. This causes the nucleus to.

The emission of several neutrons in the fission process leads to the possibility of a chain reaction if at least one of the fission neutrons induces fission in another fissile nucleus which in turn fissions and emits neutrons to continue the chain. The process may be controlled nuclear power or uncontrolled nuclear weapons. If more than one neutron is effective in inducing fission in other.

When these neutrons collide with and induce fission in other neighboring nuclei a self sustaining series of nuclear fission reactions known as a nuclear chain reaction can result figure 2162. One of the most well known and useful examples of a chain reaction is of u 235 which is used to harness nuclear energy. You cant have a chain reaction with u 238.

Nuclear fission is the splitting of a large atomic nucleus into smaller nuclei.
