Microscopic Cross Section Generation of Generation IV Nuclear Reactors for VISTA Project

摘要

Nuclear Fuel Cycle Simulation System (VISTA) is a scenario based computer model for the estimation of fuel cycle service requirements. It has been developed by the IAEA. The model has been designed to estimate fuel cycle requirements and actinide arisings. The microscopic cross section evaluation for the generation Ⅳ nuclear reactors must be carried out for the future development of VISTA. In this study, microscopic cross sections were generated for Pebble Bed Modular Reactor (PBMR) and Gas Turbine Modular Helium Reactor (GT-MHR) by using Monte Carlo code MCNP-4B and depletion code BURN-HUNEM to use in VISTA.
