Experimental Study of the Temperature Field in Fire Caused by Sodium Leakage in Sodium-Cooled Fast Reactor Loop

Article Preview

Abstract:

In order to explore the characteristics of fire caused by sodium leakage in sodium-cooled fast reactor loop, an experiment on the sodium fire in form of columnar flow has been conducted. Temperature field characteristics were analyzed by measured results. Near the axis of the combustion container, the high-temperature region of the sodium fire in form of the columnar flow is located in the bottom and the temperatures are all less than 100°C at height from 0.5m to 2.0m under natural ventilation. The temperatures of the space reach the maximum values after forced ventilation and the highest temperature is up to 950°C at height 0.8m above the ground. Once the lateral distance to the sodium flow is more than 0.4m, the temperature field is affected less by the sodium fire in form of columnar flow.
