The result of GEANT4 simulation of neutron photoproduction on deuterium and oxygen-16 is presented below:

Neutron yield ($4\pi$) from $D_2O$ (90%$D_2$ concentration) in reaction $O16(\gamma,n)O15$ is presented below. 410 neutrons initially produced got absorbed in the target (E=0MeV) and 2509 neutrons will likely escape the target:

Neutron yield ($4\pi$) from $D_2O$ (90%$D_2$ concentration) in reaction $D_2(\gamma,n)p$ is presented below. 857 neutrons initially produced got absorbed in the target (E=0MeV) and 17656 neutrons will likely escape the target:
