A dataset for thermal stratification phenomenon in lead-cooled fast reactors

The system integrates experimental and numerical simulation data from 32 publicly published literature at home and abroad, including data from different reactors under typical accident conditions such as steady-state, transient, and unprotected loss of heat trap (ULOHS), protected loss of flow (PLOF), etc.

The data was digitally extracted from literature curve graphs using Origin software, and its reliability was ensured through three independent extraction verifications. It was classified and stored using a structured metadata framework (including identification traceability, geometric space, physical conditions, and nine core fields of data content), with unified physical quantity units (temperature in Kelvin K, time in seconds, etc.) and standardized output in CSV format.
