Concentration levels of solutes in porous deposits with chimneys under wick boiling conditions

Concentration levels of infinitely soluble solutes in porous deposits with chimneys, for which wick boiling appears to be the major mode of heat transfer, has been investigated by a two-dimensional model. Wick boiling promotes the development of high concentration levels of solutes within porous deposits, especially in the region near the intersection of the heating surface and the chimney wall. The maximum concentration factor increases with decreasing porosity; with increasing chimney population; with increasing system pressure in the range of system pressures of interest to LWRs, and approximately exponentially with both increasing heat flux and crud thickness
