A study on the safety measures of LMR coolant -Liquid metal reactor development-

Technical Report:

Abstract

A study on safety measures of LMR coolant showed the results as follows ; 1. LMR coolant safety measure: (1) Peak gas pressure decreases significantly when the droplet diameter is increased, but peak gas pressure increases with initial oxygen concentration, sodium quantity and sodium temperature. (2) The surface combustion model was used for the analysis of sodium pool fire in a test vessel. It was turned out that this model showed the over estimation results about the combustion rate and sodium temperature in comparison with experimental results. 2. Sodium fire aerosol characteristics: (1) Aerodynamic mean diameter decrease according to increase of measuring times, injection temperature and injection pressures. (2) Combined sodium fire aerosols and spray fire aerosols are classified the same from the point view of aerosol characteristics. 3. Sodium purification technology: (1) The major design parameters of the cold trap are cooling method, trapping temperature, residence time and flow rate. A residence time of 3-5 min and a flow rate of 1-20 g/min are desirably accepted by cold trap designers. (2) The important factors for design and performance of plugging meter are size and type of flow restrictor, sodium flow rate, cooling rate. 4. The characteristics of sodium-water reaction:  More>>
