Waste immobilization in glass and ceramic based hosts : Radioactive. toxic and hazardous wastes
In the case of radioactive wastes from reprocessed nuclear fuel and certain defence operations, vitrification has been the vanguard of past and current treatment options. More recently, the threat of global warming and the need for low carbon energy sources has brought nuclear issues back to the forefront of scientific, technical and public awareness, with the building of new nuclear power plants, coupled with the longer term likelihood of a future generation of advanced closed fuel cycle nuclear energy systems, the so-called Generation IV systems (GenIV). As worldwide demand for uranium increases with these new requirements, and stocks are depleted, fuel recycling, with the corresponding generation of various categories of radioactive wastes, will become an ever more important issue. Of serious concern at this time is the lack of specialists in areas relating to nuclear . power and particularly nuclear waste, and this book provides an up-to-date reference source at this critical time, with the emphasis on waste irnmobilization. On the other hand, it is becoming increasingly essential from an environmental perspective, as regulated land-fill sites become full and/or more expensive, that more be done to address problems associated with the ever increasing volume of nonradioactive hazardous wastes, until recently treated with somewhat less respect than their radioactive counterparts. One solution to this problem is to turn hazardous wastes into vitrified or ceramic products where the hazardous elements are chemically immobilized and made passively safe, and it is in this area that certain practical lessons can be learnt from the nuclear industry with its long history and experience of waste treatment and vitrification technologies. An added advantage and incentive in the case of nonradioactive wastes is that, rather than generating a product that must be disposed of, treatment may actually turn hazardous wastes into useful products with practical applications.
