We applied the two-dimensional lattice Boltzmann method (2DLBM) to the simulation of solution chemistry for crevice corrosion. The 2D distributions of pH and electric potential were obtained by the numerical simulation. The critical value of pH which brings about the rapid crevice corrosion and the incubation period until the solution reaches this pH were estimated from the simulation results. It was found that the estimated pH and incubation period were in nearly agreement with experiment.

The whole monitoring system including a data acquisition system and the advisory displays has been tested by an on-line simulator of pressurized water reactor. From the testing results, it was shown that the neural network in the monitoring system successfully modeled the plant dynamics and detected the symptoms of anomalies earlier than the conventional alarm system. The real-time expert system also worked satisfactorily in diagnosing and displaying the system status by using the outputs of neural networks and a priori knowledge base.
