Why is differential neutron flux commonly used in nuclear reactors?

[oksuz_]

Hi,

Below are the neutron flux spectra of a nuclear reactor. In the first spectrum, y-axis is differential flux and in the second spectrum, y-axis is flux (created by multiplying differential flux by energy in MeV). As far as I have seen so far, differential flux is used commonly. I am just wondering that why it is like that. Is there an advantage for using differential flux instead of just flux?

Thank you.

Off hand, I would say it depends on what information you are looking for.

Hi
It permits to compare the spectra even if the sampling (delta E) is different

Hello, I have seen also in some papers Integral neutron flux. I am trying to obtain it just as unfolding codes as SANDP or STAYS´L do. If somebody knows how to do that calculations I will appreciate it. The behavior in the integral neutron flux is also different from those shown previously. Thank you very much
