Progress on a corrosion study of low carbon steel for HLW container in a simulated geological disposal environment in China

In a multi-barrier system of geological disposal for high-level radioactive waste (HLW), it is considered that the disposal container is the first layer of protective barrier to HLW. Low carbon steel is considered as the most promising candidate material for geological disposal container given its m...
