Fission neutron classification

Scission neutrons are specifically the subset of prompt neutrons that are emitted at the time of scission, which is when the nucleus splits into two fission fragments. These neutrons have a lower yield, estimated to be between 10%-20% of all prompt neutrons, and also have a lower energy and more isotropic emission compared to other prompt neutrons. In summary, scission neutrons are a type of prompt neutrons that are specifically emitted at the time of scission during the fission process and have a lower yield and different energy and angular emission spectrum compared to other prompt neutrons.

"Looking at time behaviour of neutrons in a reactor on time scales of both ~sec and ~days/months
Start with fission process
e.g. 235U + n -> 236U ->fission
Usually divide into 2 Fission Fragments
10%-20% of fission emit a scission neutron
(i.e. at time of scission)"

I've heard about prompt neutrons and delay neutrons, but what is scission neutrons?
By means of scission I think it's prompt neutrons, but I don't think the yield of prompt neutrons is that low.
Does anyone know any thing about scission neutrons?

1. What is fission neutron classification?

Fission neutron classification is a process used to categorize neutrons produced during nuclear fission reactions. This involves classifying neutrons based on their energy levels, as well as their likelihood of causing further fission or being absorbed by other materials.

2. How are fission neutrons classified?

Fission neutrons are typically classified into three categories: slow, thermal, and fast neutrons. Slow neutrons have low energy levels and are more likely to cause further fission, while thermal neutrons have a slightly higher energy and are more easily absorbed by other materials. Fast neutrons have the highest energy levels and are less likely to cause further fission or be absorbed.

3. Why is fission neutron classification important?

Fission neutron classification is important because it helps scientists understand and control nuclear reactions. By knowing the energy levels and behavior of different types of neutrons, scientists can design reactors and nuclear processes more effectively and safely.

4. How is fission neutron classification used in nuclear power?

In nuclear power plants, fission neutron classification is used to control the reaction rate and maintain a steady flow of energy. By controlling the types of neutrons present in the reactor, engineers can regulate the rate of fission and ensure safe and efficient energy production.

5. Are there any other applications of fission neutron classification?

Yes, fission neutron classification is also used in nuclear weapons development, as well as in medical and research applications. In these fields, scientists may intentionally produce and manipulate specific types of neutrons for various purposes.
