Abstract

The high temperature corrosion of the 12Kh18N10T steel in molten lithium and potassium chlorides with a cerium trichloride addition is studied at 773 K. The CeCl3 concentration is varied from 0.2 to 5 mol %. Cerium is used as an analog of plutonium. The electrolyte composition is close to the compositions of the real electrolytes used for processing of nitride spent nuclear fuel. The main research method is gravimetry, with holding a steel sample in a melt for 1–24 h. In addition, atomic adsorption and electron-probe microanalysis are used.

Keywords:
