Abstract Scope |
Obtaining a license for a new nuclear reactor requires assessment of the potential consequences of specified accident scenarios. Sparse experimental data on molten salt reactor accidents limits the development of accident scenario models. This work emulates potential atmosphere and temperature variation in a molten salt reactor accident scenario to analyze the resulting salt splatter distribution and aerosol products. A 10g batch of FLiNaZr eutectic salt mixture (LiF-NaF-ZrF, 26.0-37.0-37.0 mol%) was heated to 500-800˚C in an argon atmosphere furnace then poured into a salt spill containment box in air with RH 20-80%. Splatter distribution, particle size, and composition of detected aerosols were impacted by the salt temperature and relative humidity inside the spill box. Additionally, the composition and thermal properties of a FLiNaZr eutectic salt containing surrogate fission products has been studied for use in future salt spill tests. These results are essential for molten salt reactor accident model development. |
