Polarographic Analysis in Nuclear Fuel Reprocessing

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...

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...

Costs of Reprocessing Versus Directly Disposing of Spent Nuclear Fuel

Spent Fuel Reprocessing: an Overview

India has entered in the field of spent fuel reprocessing as early as sixties by way of R&D studies and finalising the process flow sheet. India's first spent fuel reprocessing plant was commissioned in the year 1965 at Trombay to reprocess spent fuel arising from research reactors. The recovered plutonium is being utilised to feed various programmes of the department. With the passage of time,...

Fast Reactor Fuel Reprocessing Technology in India

The limited indigenous uranium resource coupled with the need of energy independence necessitated the Department of Atomic Energy (DAE) in India to opt for a three-stage nuclear power program comprising of PHWRs in Stage 1, FBRs in Stage 2 and Th-U based reactors in Stage 3, respectively to meet the energy needs of the growing Indian economy. Presently the country has stepped into the 2nd Stage...
