Abstract

TRISO-coated particle fuel is extensively utilized in high-temperature gas-cooled reactors and other advanced reactors. The performance of these coated fuel particles is crucial for reactor safety. It^s essential to assess and determine the failure probability of coated fuel particles using appropriate fuel performance models and methods under both normal and accident conditions. To enhance the design process of coated particle fuel, a new TRISO fuel performance code-named TRIAC-BATAN was developed. This code is designed to calculate internal gas pressure, mechanical stress, and failure probability of coated fuel particles. This paper introduces TRIAC and benchmarks it against IAEA CRP-6 (tecdoc IAEA 1674 chapter 9) benchmark cases for analyzing coated particle failure, especially for tangential stress maximal. TRIAC-BATAN^s results align well with benchmark values, demonstrating its accuracy and applicability, particularly for tangential stress maximal. This work establishes a reliable foundation for the application of TRIAC-BATAN.
