Abstract

This study introduces a leakage area estimation model based on multi-objective optimization and the development of a CONTAM-Python integration. The tool automates the adjustment process of assumptions and enables efficient search for leakage areas to validate pressure difference models. The model is applied to a reference-based model that exhibits over-pressure. The proposed approach successfully reduces errors compared to the traditional method using reference values. By refining input parameters in Stage 1 to Stage 3, the performance of the model is further enhanced, indicating the potential for establishing a more detailed and accurate validation model.
