THE APPLICATION OF BIOTECHNOLOGY TO THE TREATMENT OF WASTES PRODUCED FROM THE NUCLEAR-FUEL CYCLE - BIODEGRADATION AND BIOACCUMULATION AS A MEANS OF TREATING RADIONUCLIDE-CONTAINING STREAMS

Recent concerns on the radiotoxicity and longevity of nuclides have prompted the development of new technologies for their removal from wastes produced from nuclear power programs and nuclear fuel reprocessing activities. Alongside developments from traditional chemical treatment processes, interest has also centered on the application of biotechnology for efficient waste treatment. Many biological techniques have relied on empirical approaches in simple model systems, with scant regard to the nature and volume of actual target wastes; such considerations may limit the application of the new technologies in practice. This review aims to identify some of the likely problems, to discuss the various approaches under current consideration, and to evaluate ways in which either the target waste or the detoxifying biomass may be modified or presented for the most efficient treatment.
