A cross section from a Ta crucible used in numerous Molten Salt Extraction (MSE) runs was submitted to metallography to determine the soundness of the crucible wall, type of Pu attack, depth of wall penetration by the Pu and general microstructure. The crucible contained molten Pu and Am, with CaCl{sub 2}, KCl and PuCl{sub 3} salts ran at temperatures of 750{degree}C to 900{degree}C for approximately 10 to 12 hours. This report documents the findings of this study.
