Abstract

Uncertainty analysis was developed in the TRISO TRIAC-BATAN fuel performance code including the Latin Hypercube Sampling (LHS) and Standard Random Sampling (SRS). The study of the comparison of the two uncertainty analyses was also carried out. One of the main challenges for improving the performance of Tristructural-Isotropic (TRISO) fuels is the ability to accommodate uncertainties related to TRISO fuel design. In addition to SRS, the LHS method was added because it allows for the extraction of information in sufficient quantities with a relatively small sample size that is suitable for challenges in analysing the performance of TRISO fuels. In this study, LHS and SRS are used as sampling methods, while uniform and triangle probability density (PDF) functions are used to represent the characteristics of uncertainty from design data. It was found that LHS was better than SRS in terms of representing PDF uncertainty. However, in the TRISO fuel performance analysis, the LHS results with a higher standard deviation compared to the SRS method.
