31P NMR Spectroscopic Analysis of Radiolysis Products in Extraction Solvent for 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...

Costs of Reprocessing Versus Directly Disposing of Spent Nuclear Fuel

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...

Quantitative analysis of phospholipids by 31P-NMR.

High-field 31P nuclear magnetic resonance spectroscopy was used to quantitate phospholipids in mixtures in organic solvents. The sample is dissolved in chloroform-methanol and analyzed at 161.7 MHz with decoupling of the protons. Signals were identified using authentic compounds, and their relative distribution was measured in mole percent. The method has good accuracy and reproducibility, and ...
