研究目的
Investigating the visualization of corium fragments in sodium during Fuel Coolant Interaction (FCI) using high energy X-ray imaging to understand the three-phase distribution within the system.
研究成果
The study concludes that while individual corium particles are smaller than the detection limit of the X-ray system, clouds of particles can be visualized. The contrast to noise ratio improves with higher mass of corium in the cloud. Future work includes manufacturing physical phantoms based on these simulations for experimental validation.
研究不足
The small size of corium particulates (around 1 mm) poses a challenge for detection with the X-ray system. The study relies on simulating clouds of particles rather than individual particles due to detection limits.
1：Experimental Design and Method Selection:
The study involves the development of a high energy X-ray imaging system to visualize the interaction between corium and sodium. The methodology includes the use of MODHERATO, an in-house tool for simulating radiographic images.
2：Sample Selection and Data Sources:
The study reviews past experiments on corium-sodium interaction to estimate particle size and shape. Data from these experiments are used to simulate expected images.
3：List of Experimental Equipment and Materials:
The equipment includes a 15 MeV Linear accelerator, GADOX screen, and CMOS camera. Materials involved are corium, liquid sodium, and vapor sodium.
4：Experimental Procedures and Operational Workflow:
The procedure involves simulating clouds of particles with varying densities of corium and sodium to study detectability using the X-ray system.
5：Data Analysis Methods:
The analysis involves using ImageJ tool to evaluate the contrast to noise ratio of the simulated images.
