title = "Development of two-step reactor physics analysis procedure for advanced high temperature reactors",
abstract = "This paper presents the investigation and development of an adapted lattice physics-to-core simulator two-step procedure based on the SERPENT and NESTLE neutronics codes for the rapid analysis of the Advanced High Temperature Reactor (AHTR). AHTR-specific characteristics such as a longer neutron diffusion length and double heterogeneity of TRISO fuel particles were taken into consideration when adapting the traditional light water reactor (LWR) lattice to the nodal diffusion procedure for AHTR applications. The procedure was tested against SERPENT-based high fidelity reference benchmark models and was deemed to provide reasonably accurate results, with the exception of some peripheral radial power discrepancies attributed to the inadequacy of the 1-D radial reflector model to capture a 1/2 symmetric and cyclic power tilt unique to the AHTR fuel assembly design and core layout.",
