None /process/inactivate nFission neutron

Good day. I try to check the results from interaction protons of 200-1000 MeV with U238 material of Target without fission. For this i inactivate nFission procces by input file, but as I can see - the results have the same value (nFission was not inactivated or was activated double ), later i tried to simulate neutron with 1-2 Mev in average energy of reactor core with same idea - but I had given neutrons from fission processes. How I can inactivate fission in macro input file with initialisation bash commands or it's easy to prevent fission by changing C source?

Input:

Thanks, Best regards, Aleksey
