Disponível em: http://repositorio.ipen.br/handle/123456789/28191.http://repositorio.ipen.br/handle/123456789/28191The objective of this paper is to verify the validity and accuracy of the results provided by programs FRAPCON-3.4a and FRAPTRAN behavior of Pressurized Water Reactors (PWR) fuel rods, in steady conditions at high burnup. To achieve this goal, the results provided by these computer simulations are compared with experimental data available in the database FUMEX III. found that the computer programs used have a good ability to predict the operational behavior of PWR fuel rods in high burnup steady Accident (RIA).openAccessaccuracyburnupcomputerized simulationf codesfuel rodsirradiationnuclear fuelspwr type reactorsreactivity-initiated accidentssteady-state conditionstransientsuranium oxidesvalidationzircaloy 4Texto completo de eventohttps://orcid.org/0000-0002-7308-5784
