||Increased corrosion resistance of the nuclear waste storage materials is critical to prevent premature degradation of these materials and restrict radioactive products escape into environment. This will result in ensuring necessary long term secure storage of nuclear waste and restrain active fission products from breaking out and contaminating the environment. This meeting will enclose two major sections: 1) Research to improve corrosion resistance of the presently in use nuclear waste storage materials: glass, ceramics, stainless steel. 2) Development of a different materials system with superior corrosion resistance for storage of nuclear waste. This symposium will give researchers worldwide an opportunity to discuss research undertaken into improving corrosion resistance for the materials used so far to store nuclear waste: glass, ceramics, stainless steel. Researchers will also have the opportunity to discuss new directions for development-based research into new, different choice of materials system for improved security storage of long-term nuclear waste.
