Abstract Scope |
Lead-Bismuth Eutectic (LBE) are used in systems as coolant to convert energy as it possesses desired properties like large difference between melting and boiling point, low neutron absorptivity and non-reactive with water. Niobium alloy is used as coolant channels in Compact High Temperature Reactors (CHTR). The corrosion of parent material and welded sample is carried out in LBE in static condition at the temperature of 1035 °C in the open air to study the combined effect of corrosion by oxygen and LBE. The corrosion test is followed by measurement of weight loss, dimensional change, X-ray diffraction and SEM/EDS analysis. It is observed that the change in weight and dimension can be attributed to the formation of unstable oxides of niobium. The present study is useful in finding the feasibility of niobium alloy as structural material for coolant channels used in CHTR. |
