The current design of the Salt Waste Processing Facility (SWPF) includes an auxiliary facility, the Actinide Finishing Facility, which provides a second contact of monosodium titanate (MST) to remove soluble actinides and strontium from waste if needed. This treatment will occur after cesium removal by Caustic-Side Solvent Extraction (CSSX). Although the process changes and safety basis implications have not yet been analyzed, provisions also exist to recover the MST from this operation and return to the initial actinide removal step in the SWPF for an additional (third) contact with fresh waste. A U.S. Department of Energy (DOE) request identified the need to study the following issues involving this application of MST: Determine the effect of organics from the solvent extraction (CSSX) process on radionuclide sorption by MST; Determine the efficiency of re-using MST for multiple contacts; and Examine fissile loading on MST under conditions using a waste containing significantly elevated concentrations of plutonium, uranium, neptunium, and strontium. This report describes the results of three experimental studies conducted to address these needs: (1) Addition of high concentrations of entrained CSSX solvent had no noticeable effect, over a two week period, on the sorption of the actinides and strontium by MST in a direct comparison experiment. (2) Test results show that MST still retains appreciable capacity after being used once. For instance, reused MST--in the presence of entrained solvent--continued to sorb actinides and strontium. (3) A single batch of MST was used to sequentially contact five volumes of a simulant solution containing elevated concentrations of the radionuclides of interest. After the five contacts, we measured the following solution actinide loadings on the MST: plutonium: 0.884 {+-} 0.00539 wt % or (1.02 {+-} 0.0112) E+04 {micro}g/g MST, uranium: 12.1 {+-} 0.786 wt % or (1.40 {+-} 0.104) E+05 {micro}g/g MST, and neptunium: 0.426 {+-} 0.00406 wt % or (4.92 {+-} 0.0923) E+03 {micro}g/g MST. (4) Over the duration of an experiment with the sequential strikes, the ability of MST to sorb actinides improved with additional strikes. This trend is counter-intuitive, but is confirmed by replicate experiments for plutonium, uranium, and neptunium. Conversely, over the duration of the experiment, the ability of MST to sorb strontium decreased the more it was used. This trend is confirmed by replicate experiment.

This book adopts a new and accessible approach to helping readers understand how management accounting contributes to decisions in a variety of organisational contexts. It sets out clear explanations of practical management accounting techniques in the context of the application of these techniques to decisions. It recognizes practice through case studies and summarises published research. Uniquely, it examines the analytical and critical issues that often influence decision makers operating within private and public sector organisations. Key features include: - Case studies of varying complexity that will allow students to work at their own level - Summaries of important research articles - Key learning objectives and end of chapter questions.

A Mathematical Dictionary for Schools contains over 500 definitions of technical terms found within GCSE syllabuses. Key words and phrases are explained in clear, simple language with illustrations to aid understanding of more difficult terms. It has been written for key stages 1/GCSE students but is also suitable for key stage 3 and is the ideal companion for coursework and revision.

A reference which gives details of all those ships whose primary role has been to operate aircraft at sea, including ships from the British Royal Navy, the Royal Australian Navy, the Royal Canadian Navy/Canadian Armed Forces and the Indian Navy, as well as many vessels that served with the US Navy.

This book for teachers suggests projects which cater for a wide range of concepts and skills, and links with other curriculum subjects.

NATO has traditionally relied on its technological superiority to offset the Warsaw Pact''s numerical advantage. This equation, however, is becoming increasingly difficult to sustain. Despite NATO''s considerably greater outlays for defense, the numerical balance continues to favor the Warsaw Pact and the technological "gap" between East and West is narrowing. To rectify this situation NATO has two courses of actionóembrace a spectrum of new technologies which offer the prospect of dramatic improvements in capability, or extract better value for the money from its defense allocations. These two possibilities need not be mutually exclusive, although historically they have been. Clearly, NATO must reform its approach to weapons procurement if it is to exploit new technology as effectively as possible in periods of budgetary stringency. The need for reform is evident: The Warsaw Pact spends less than NATO on defense but outproduces NATO in virtually every weapons category. This volume examines these problems and shows that in order to exploit available technologies at an affordable cost, NATO clearly must organize its defense procurement more efficiently.
