In this paper we have analyzed energy transport by relativistic neutrons from the core of active galactic nuclei (AGNs). Two models of AGNs have been considered: accretion of matter onto a supermassive black hole, and supernova-like expanding shocks produced by numerous destructive stellar collisions. It is shown that, assuming efficient acceleration of heavy nuclei in the acceleration region of AGNs, about half of the acceleration power of the nucleus is transferred to relativistic neutrons, which then escape from the region of the strong magnetic field. The process of photodisintegration (A gamma) of nuclei has been considered. The neutron luminosity can be 1.5 times greater than that expected from p-p and gamma-p interactions.
