Nuclear Fuel Reprocessing Technologies and Commercialization

New approaches to reprocessing of oxide nuclear fuel

Dissolution of UO2, U3O8, and solid solutions of actinides in UO2 in subacid aqueous solutions (pH 0.9-1.4) of Fe(III) nitrate was studied. Complete dissolution of the oxides is attained at a molar ratio of ferric nitrate to uranium of 1.6. During this process actinides pass into the solution in the form of U(VI), Np(V), Pu(III), and Am(III). In the solutions obtained U(VI) is stable both at ro...

Cost analysis of the US spent nuclear fuel reprocessing facility

a r t i c l e i n f o The US Department of Energy is actively seeking ways in which to delay or obviate the need for additional nuclear waste repositories beyond Yucca Mountain. All of the realistic approaches require the reprocessing of spent nuclear fuel. However, the US currently lacks the infrastructure to do this and the costs of building and operating the required facilities are poorly es...

Costs of Reprocessing Versus Directly Disposing of Spent Nuclear Fuel

Innovative Technologies for Nuclear Fuel Cycles and Nuclear Power

At the present stage of development no single energy resource or technology constitutes a panacea toaddress all issues. Therefore, it is necessary that all low-carbon and non-carbon emitting resources become anintegral part of an energy mix – as diversified as possible – to ensure energy security to the world during thepresent century. Available sources are low carbon fossil fuels, ...
