Abstract: One of the tasks of the Brazilian Nuclear Energy Commission (CNEN) is to perform independent calculations related to the thermo-mechanical behaviour of the fuel elements used in the Angra I and Angra II nuclear power plants. For this purpose, well-established computer codes are used to ensure that the safety analysis reports submitted by the operator do not violate any aspect related to plant safety. In this paper, the eighth reload cycle of the Angra I Power Plant was simulated using the Brazilian Code of Reactor Physics (CNFR), a neutronic simulation code developed in Brazil specifically for nuclear power plants in operation in the country and made available for use by the CNEN. This cycle was chosen because the loading of nuclear fuel used took place entirely with fresh fuel. The fuel burnup simulated with the CNFR code and the power history considered were coupled to the FRAPCON code to simulate the thermo-mechanical behaviour of the fuel rod considered. The results obtained were consistent with those reported by the operator using the Alpha/Phoenix-P/Anc (APA) methodology.
