Nuclear wastes are an important part of the overall waste disposal problem Like hazardous chemical wastes, we will limit our discus- sion to the risks imposed by civilian wastes Nuclear power plants produce the greatest amounts of civilian high-level radioactive wastes, measured in Curies (Ci) per year

the nuclear waste problem confronting DOE He recog-nized that although cesium accounted for over 90 percent of the radioactivity in the waste that can dissolve in water it amounted to a tiny fraction of the total waste—less than 1/10000th by weight—so that it might be possible to greatly decontaminate the waste by removing the small
In preparing a given site for disposal of waste local stresses will be generated by mining but after emplacement of waste thermal stresses may build up for a long period of time The
9 Nuclear Waste Disposal Problems associated with nuclear power are often magnified in the public eye But the problems of nuclear waste disposal are in fact complex and serious These problems are being solved but their solution requires ingenuity and commitment It will help at the outset to develop a few perspectives about nuclear waste
Plans for disposing of radioactive wastes have raised a number of unique and mostly philosophical problems mainly due to the very long time-scales which have

31 oct 2022 · An early assessment of waste management needs from development and use of advanced reactors and innovative nuclear fuel cycles is required to
What type of radioactive waste is generated in nuclear power plants?
In normal operation of nuclear power plants, someairborne radioactive wastes are generated in either par-ticulate or aerosol of gaseous form. Paniculate radioac-tive aerosols can be generated in a wide range of particlesizes in either liquid or solid form, possibly in combina-tion with non-radioactive aerosols.
Do nuclear power plants use pre-coated filters?
Pre-coated filters used at nuclear power plants toprocess liquid waste produce another type of wet solidwaste-filter sludges. The filter aids — usually diato-maccous earth or cellulose fibres — and the crud that isremoved from the liquid waste together form the filtersludges. Some filtration systems do not require filter aidmaterials.
Why do different types of reactors produce different waste streams?
According to the different.types of reactors now oper-ating commercially all over the world, different wastestreams arise. These streams are different both inactivity content and in the amount of liquid waste gener-ated. Reactors cooled and moderated by water generatemore liquid waste than those cooled by gas.
Is evaporation a good treatment method for radioactive waste?
Evaporation is a proven method for the treatment ofliquid radioactive waste providing both good decontami-nation and volume reduction.
