Purpose of the course: Safe disposal of hazardous wastes is one of the most important environmental problems that we face today. In this course, the primary focus will be on the radioactive wastes and their disposal. Vitrification is considered to be one of the most reliable methods for long term storage of radioactive wastes. The main objective of this course is to lay down the radioactive waste problem, introduce the methods investigated for long term disposal of these wastes and study the vitrification of nuclear wastes in detail.
