What is the equation for the neutron diffusion?
The continuity equation involves both neutron current J(r,t) and neutron flux ϕ(r,t) , where the relationship between current and the flux can be shown using Fick's law, which is given in the following mathematical equation: J(r,t)=u221.
- D∇ϕ(r,t), where D is the diffusion coefficient
What is the neutron transport algorithm?
The neutron transport equation is a balance statement that conserves neutrons.
Each term represents a gain or a loss of a neutron, and the balance, in essence, claims that neutrons gained equals neutrons lost.
It is formulated as follows: Average number of neutrons produced per fission (e.g., 2.43 for U-235)..
What is the neutron transport problem?
The neutron transport equation with boundary conditions defines an initial value problem.
If the neutron angular density at t = 0 is given, the expected density at any later time can be found, in principle, by solving the neutron transport equation..
What is the transport theory of the neutron?

Each term represents a gain or a loss of a neutron, and the balance, in essence, claims that neutrons gained equals neutrons lost.
It is formulated as follows: Average number of neutrons produced per fission (e.g., 2.43 for U-235)..
What is the transportation of neutrons?
The neutron transport equation (NTE) is a conservation equation that describes how many neutrons enter or leave a phase space defined by the position, angles of motion, energy, and time of a neutron..
- Neutron is diffused from high to low concentration area according to Fick's law of. diffusion.
While going through the moderator medium fast neutron are slowed down.
It is found that Fermi age and thermal diffusion length of neutron is smaller in light and heavy water than graphite or beryllium. - The Boltzmann transport equation describes the transport of neutral particles from one collision with an atom to another.
It is a 'balance' statement that accounts for additions to and subtractions from the radiation in a given increment of space, energy, direction and time. - The continuity equation involves both neutron current J(r,t) and neutron flux ϕ(r,t) , where the relationship between current and the flux can be shown using Fick's law, which is given in the following mathematical equation: J(r,t)=u221.
