Dear FLUKA experts,
During the setup process of the fixed neutron source in the PWR core, I hope to turn off the secondary fission neutrons in the core simulation. When I intend to use the user routine to turn off the secondary fission neutrons in the core, I can only find the secondary neutron identifier kpart related to hadron events. Could you please tell me if there is a symbol that can accurately identify the fission secondary neutrons and inform me of its source?
Any guidance or reference to the relevant manual sections would be highly appreciated.
Best regards,
Yingming
