Lanthanide borosilicate glasses containing Pu and the nonradioactive analog element Ce were subjects of an x-ray absorption spectroscopy investigation to quantify +3/+4 ratio these redox-sensitive elements. The data show that dominant oxidation states are +4 for +3 Ce. also indicate reductive potential can be quantified from a solution chemistry method adapted glass chemistry, although allowanc...

Transmutation of burnup products for a typical VVER-1000 reactor in fusion-fission hybrid has been investigated using MCNPX 2.6.0 calculation code. Burnup fission was performed 1000 MW practical power VVER core UO2 fuel and light water as its coolant moderator, well. The have classified separated according to their half-lives usages, the remaining wastes were used fuels reactor. also implemente...

Two comments can be made on this matter. First, it is likely that nuclear power is safe based on short-term issues; the imponderables that carry weight with the objectors are the uncertainties of major accidents, long-term wastes and proliferation. Current risk studies do not banish these fears. Secondly, if these studies aim to influence choice of energy mix for the future, they should extrapo...

The accident at the Fukushima Daiichi Nuclear Power Plant in 2011 released many radioactive elements into environment, contaminating a large amount of soil. Currently, 14 million m3 contaminated soil is scheduled for interim storage, and final disposal planned by 2045. In future, decommissioning plant will generate great waste. Therefore, reduction volume soil, which accounts ~90% wastes, probl...

Contamination of soils, water, and sediments by radionuclides and toxic metals from uranium mill tailings, nuclear fuel manufacturing and nuclear weapons production is a major concern. Studies of the mechanisms of biotransformation of uranium and toxic metals under various microbial process conditions has resulted in the development of two treatment processes: (i) stabilization of uranium and t...
