    Abstract

    This paper presents the early development of a coupled neutron / photon transport mode in the Serpent 2 Monte Carlo code. The methodology covers the production of prompt secondary gammas emitted in neutron interactions, using the ENDF reaction sampling laws in ACE format cross section libraries. The new transport mode is developed mainly to account for the effect of gamma heating in multi-physics simulations. Other potential applications include radiation shielding and fusion neutronics. The work is still under way, and at the time of this writing the distributed version of Serpent 2 lacks the capability to transport both neutrons and secondary photons simultaneously. The methodology is instead tested and demonstrated by dividing the simulation in two parts, and the results are compared to reference MCNP calculations. The test cases include a simple broomstick problem for the comparison of photon emission spectra, and gamma flux and heating calculations in an infinite BWR fuel lattice.
