"Nuclear reactor installations designed for power production must of necessity operate at higher energy levels than their experimental precursors. As these facilities increase in number, better solutions must be found for both technical and economic problems.
The disposal of waste materials is of primary importance and will require greater effort if satisfactory disposal methods are to keep pace with the increase of waste materials, produced by the increasing number of new nuclear facilities. The radioactive materials present in this waste material may constitute a valuable by-product from these operations if suitable and economic recovery procedures are developed. If the development of recovery methods is sufficiently in advance of nuclear installations, further inducement for installations of this type may be offered. The extent to which nuclear power generation methods will be used will greatly depend upon the economic factors which enhance or hinder competition with conventional power generation methods.
There are many reports of investigations designed to determine methods and conditions for the separation of fission products from various mixtures of isotopes in different solutions. One of the most perplexing phenomena is the behavior of zirconium. Not only is there lack of information, but there are even conflicting reports regarding the species in various solutions and the extent to which they can he removed by such methods as electrodialysis precipitation, ion-exchange and liquid-liquid extraction.
This investigation was undertaken primarily to determine the extent to which zirconium could be separated by electrodialysis from solutions of hydrochloric, hydrofluoric, sulfuric, nitric, perchloric or oxalic acid solutions, at various acid concentration ranges with the expectation that the data thus obtained would be of value to those designing facilities for separation of zirconium by electrodialysis. In addition, the information may be useful for determining the nature of the zirconium complex in these solutions where a knowledge of the charge carried serves to eliminate a proposed species or confirm another.
It is, of course, realized that exact determination of the composition of the zirconium species must await further studies along different lines, and this information contributes only to those species which may be accepted or rejected by qualitative arguments relating to the charge carried by the species"--Introduction, pages 1-2.
