Moderator heat sources in TEPLATOR district heating SMR

Original language description

Moderator temperature needs to be maintained below safe values in reactors with separated moderator and coolant volumes. For reactor during full power operation, main heat sources relevant to moderator volume temperature are heat transfer from nuclear fission source and radiation heating caused by various nuclear reactions. These reactions include radiation heating from fission neutrons, secondary photons from (n,γ) reactions, fission photons, spent nuclear fuel neutrons, spent nuclear fuel photons and Co-60 photons from activated steel components. Although the radiation heating can represent less intensive heat source, it is a direct source in the moderator volume and it can affect moderator volume temperature more than relatively distant heat sources in the fuel. For reactor during outage before core unloading, heat transfer from nuclear fission is replaced by heat transfer from spent nuclear fuel decay heat. In the paper, radiation heating and its components along with SNF decay heat for TEPLATOR district heating SMR is calculated by MCNP and SCALE codes
