Application of photochemical techniques to nuclear fuel reprocessing and waste separations.

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...

construction and validation of translation metacognitive strategy questionnaire and its application to translation quality

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...

Costs of Reprocessing Versus Directly Disposing of Spent Nuclear Fuel

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...

Childhood leukaemia around the La Hague nuclear waste reprocessing plant.

the first five years of the disease. There have been a few reports of proliferative retinopathy developing at an early stage of type I diabetes,2 and proliferative retinopathy is occasionally seen as a presenting feature of type II diabetes, usually in patients aged 40 or older.' In case 1 the patient had typical type I diabetes with islet cell antibodies and no residual f cell function. The ot...
