Abstract:

According to work characteristics of heat pipe reactor， a theoretical model of the wick is established． The formula for rising height of liquid lithium in the wick is derived． The wick rising height is calculated under certain conditions． In addition， the change rules of rising height of lithium in wick with the mesh number， layer number， temperature and heat flux are analyzed． It provides the basis for the design of the heat pipe reactor and the selection of the wick parameters．
