Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

By solving the transport equation in multi-group form, then you can get the solution. or using MCNP-like code and tally the flux at defined component as you wish

Naïma Amrani

Dear Youqi

Are you able to suggest me documents to help me to create adequate MCNP file for flux calculations

Best Regards

Weixiong Zheng

Take a look at this techreport from LANL, it should help you out:

Dear Amrani,

Please see the cell calculation theme in the neutronic calculation area.

Egon János Szondi

In case of "sodium fast reactors" the whole neutron spectrum is part of the "fast spectrum". Nevertheless, the energy grid depends on the use of the results. Example: the neutron irradiation damage exposition of a certain steel can be treated as the fluence of the neutrons above 0.5 MeV, while for another steel the limit may be 1 MeV, and for the third kind the dpa (displacement per atom). You should first define the purpose of the calculational results, thereafter set up the energy grid.
