Before transferring fuel rods from the reactor core to the spent fuel pool, the state of the fuel rods after operation should be determined. The state of a fuel rod could be estimated by employing deterministic analysis. In this work, the state of the RBMK-1500 fuel rod after normal operation was evaluated using the numerical method.
Recently, analysis of the processes in RBMK-1500 fuel rods has been performed only by RBMK designers. In the last years, specialists of the Lithuanian Energy Institute started modelling the process in fuel rods of the Ignalina Nuclear Power Plant (NPP) as well, using the FEMAXI-6 code adapted to the specific features of the RBMK-1500 fuel rod. The calculation results obtained using the adapted FEMAXI-6 code were compared with calculations performed by specialists from the Kurchatov Institute. A comparison of the results shows that the adapted FEMAXI-6 code is suitable for the analysis of processes in fuel rods of the RBMK-1500.
The processes during the whole life of fuel rods were analyzed using the adapted FEMAXI-6 code. For this analysis, a fuel rod from the fuel channel with an average initial power (2.5 MW) was selected. The state of a fuel rod after operation was evaluated using numerical analysis. The obtained results can be used for the analysis of processes in fuel rods stored in spent fuel pools.
