Experimental investigation on ex-vessel debris bed formation using low melting-point melt of binary metals

Yan Xiang et al.

Summary: During severe accidents in a light water reactor, the relocation of core melt to the lower head and failure of the reactor pressure vessel (RPV) may occur. If the reactor cavity is flooded with water, the ejected corium will undergo melt coolant interactions (FCI). This study focuses on characterizing the debris bed formed from FCI of metal-rich corium failing into a deep water pool. Experimental results reveal the FCI phenomena and debris bed characteristics under different parameters.

Experimental investigation on debris bed formation from metallic melt coolant interactions

Yan Xiang et al.

Summary: A series of experiments was conducted to investigate the characteristics of metallic melt-water interactions. The results showed that water pool depth significantly influenced steam explosion and debris bed formation characteristics, and jet breakup length was sensitive to jet diameter and free fall height. Additionally, the features of metallic debris beds were compared with those of oxidic ones in terms of configuration, porosity, and particle morphology and size distribution.

Ruiyu Sun et al.

Summary: This study reviews and summarizes the experimental and theoretical research on the fuel-coolant interaction phenomenon in nuclear reactor accidents, describing the behavior of the melt throughout the entire evolution process. Models for each stage are classified based on formation mechanisms and applicable conditions, with future development directions proposed based on previous research findings.

Metallic melt jet fragmentation in a water pool: Experiments and numerical simulations

Sachin Thakre et al.

Summary: This study investigates experimental and numerical simulation of metallic melt jet fragmentation, showing the influence of Weber number on the fragmentation patterns. The experiments reveal that the jet fragmentation follows R-T instability at lower Weber numbers and K-H instability at higher Weber numbers. Measurement challenges at larger scales lead to the use of different methods for estimating jet breakup lengths. Numerical simulations considering hydrodynamic effects only underestimate the jet breakup lengths as they do not consider the presence of a vapor film.

A scoping study on debris bed formation from metallic melt coolant interactions

Yan Xiang et al.

Summary: This study focuses on the formation and characteristics of debris during a severe accident in a light water reactor, analyzing the debris bed formed by a metal-rich corium jet falling into a water pool. Experimental results show the influence of parameters like superheat and subcooling on the characteristics of the debris bed, including configuration, porosity, particle morphology, and size distribution. Preliminary comparison between metallic and oxidic debris beds was also provided.
