    Abstract

    This paper presents the photonuclear physics model implemented in Serpent 2 Monte Carlo code. The model is based on cross section data with the addition of relativistic collision kinematics and frame of reference transformation. Forced photonuclear collision mode has also been developed for efficient calculations. Photoneutron production yield calculated with Serpent 2 is compared to ENDF/B-VII.1 photonuclear data, showing excellent agreement. Serpent 2 is also compared to MCNP6 and TRIPOLI-4 by calculating photoneutron production in tungsten, lead and heavy water. The results show good agreement with TRIPOLI-4 and MCNP6 when the physics models and data used in the codes are comparable. Problems in the photoneutron production in MCNP6 and TRIPOLI-4 are also addressed.
