[1D11] High temperature reaction between metal borides and stainless steel
Keywords:metal borides, stainless steel, high temperature reaction, control rod, severe accident
Eutectic reactions between group-4 metal borides and stainless steel were examined with thermal analysis, comparing to boron carbide. The reaction temperatures ranged around 1200~1300℃, but the reaction rates for group-4 metal borides were slower than that of boron carbide. This suggested that group-4 metal borides would be suitable as control material.
