Implementation of reactor kinetic model using labview program code on functional simulator of Kartini reactor operation and control

Implementation of the reactor's kinetics model is an attempt to create a functional design of the Kartini reactor simulator. The intended implementation is to improve the results of the development of the previous reactor kinetics model, where there are still deficiencies in reactivity modeling, and the results have not been validated. This implementation is expected to realize a software simulator to describe the operation of the Kartini reactor clearer in accordance with actual conditions. The implementation of the reactor kinetics model was done using LabVIEW software with control rod reactivity, temperature, and product poisoning variables. Then parameter values were varied to obtain the results of modeling implementation by Kartini reactor operation data. Experimental data were obtained by varying the three independent parameters, namely the initial neutron density (N₀), the fraction of the passive neutron group (β), and the mass of the reactor fuel (m). The results showed that the change in free parameters is proportional to the parameters of the power and reactor period. The best modeling implementation occurs in an operation experiment with a value of N₀= 0.004; β = 0.0014 and m = 2563 grams. These results are validated by measuring reactor power parameters with three operating data and have an average accuracy of 86.0 %, and reactor period parameters with two operating data have an average accuracy of 56.6 %.
