• In order to improve the performance of the sodium vapor trap, the sodium trapping efficiency has been analyzed using a simplified model of the mesh-packed region, supplemented by considering the effect of mist formation in the trap. The results led to the following conclusions :<BR>(1) When mist containing sodium vapor is supplied to the trap, the sodium trapping efficiency is greatly lowered because of condensation of vapor to mist.<BR>(2) Even if the sodium vapor contains no mist initially, it forms when nuclei for condensation exist which are larger than a critical value. This mist formation causes a decreased sodium trapping efficiency.<BR>(3) The sodium trapping efficiency can be maximized by decreasing the gas temperature along the mesh in a manner inversely proportional to the trap length.
