AI Technical Summary
Existing sodium leakage monitoring technologies for primary loops in sodium-cooled fast reactors suffer from problems such as high detection limits, limited sensitivity, slow response speed, inability to adapt to high-temperature and high-irradiation environments, and inability to achieve large-area coverage monitoring, making it difficult to achieve ultra-early warning.
A negative pressure concentration unit is used to form a negative pressure three-dimensional rotating turbulent flow field. Combined with microwave plasma spectroscopy detection, a closed circulation gas path is constructed through a sampling and transmission mechanism. The negative pressure concentration unit and the spectral detection unit are integrated in an external mounting chassis to achieve efficient enrichment and rapid detection of micro- and nano-sized sodium aerosols.
It achieves ultra-early warning of sodium leakage, improves the detection limit, adapts to high temperature and high radiation environments, covers a large area for monitoring, reduces operation and maintenance costs, and improves the safety and reliability of the system.
