Pellet shielding mechanism described as follows: an evaporation wave front is driven into the solid by the ambient particle energy flux which evaporates the surface of the solid. This evaporated pellet material is an ionized plasma the temperature of which is initially of the order of 10 4 °K. About one half of the input power to the pellet is convected away by the expanding warm plasma cloud. This evaporated plasma cloud then helps shield the pellet surface from the incident reactor electrons.
