WebThe MCNP5 model of the NuScale reactor module comprised several units: the core, reflector, barrel, and reactor pressure vessel. The core was modeled as an 11 x 11 lattice, and each core lattice element is a 17x17 fuel/fuel-control assembly, an assembly (no fuel or control segment) with only upper and lower core plates, a reflector or coolant. WebMCNP also uses the concept ofSEGMENT in geometry definition. A seg ment is a portion ofa cell or a surface used for tallying purposes. The FS card is used to divide a eelI or a surface into segments.
