文摘
- •
MLOCA scenarios with multiple types of variabilities were simulated in a DET model.
- •
For quantification, an alternative to coupling fault trees to a DET is presented.
- •
The generated DET sequences are represented one‐to‐one with event and fault trees.
- •
DET quantification is compared to estimates based on bounding success criteria.
- •
Both the estimated MLOCA risk and dominant contributors were impacted.
