Eggers and William E. Gawthrop June 30. 197S INTRODUCTION This report presents the results of a study aimed at assessing the potentially beneficial uses of krjT)ton-85 derived from waste of gases of nuclear fuel reprocessing facilities. In this study the authors have attempted to identify candidate applications for krypton-85, assess the candidate applications (technically and economically) and point out which applications have been or could be readily implemented. Not only was the literature surveyed (1964 to present) but many persons in government, industry, and the academic community were also interviewed during the course of this study. The literature provided many of the historical data relative to krypton-85 and the nuclear Industry in general while the interviews provided very up-to- date information as to the present trends in krypton-85 uses, research, and development now going on. The interviews also provided valuable insight into new concepts for applications. While the technical assessments of the identified candidate applications were readily accomplished, the economic assessment that was attempted was not so successful. The problem of indefinite cost data for enriched krypton-85 made the economics assessment very difficult if not Impossible. Nevertheless, the authors have attempted, at least, to give order-of-magnltude estimates. 2 Sm^lARY A study of the potentially beneficial uses of by-product krypton-85 from nuclear fuel reprocessing facilities has been accomplished. The main objective of the study was to assess the potentially beneficial uses of kr3T)ton-85 by systematically identifying and evaluating candidate uses of the fission product gas in terms of technical and economic cost benefits. Major emphasis in the study was geared not only toward identifying poten tially beneficial uses but also toward identifying applications where large quantities of krypton-85 could be utilized. Furthermore, emphasis was placed upon those applications where a number of devices using krypton-85 could be realized (and not on a single device that would require the total available inventory of the gas). The overall program approach was accomplished In a project comprising four principal tasks: (1) characterization of the krypton-85, (2) identification of candidate applications, (3) technical assessments of the candidate applications, and (4) summary of the findings. The program was initiated by conducting a survey of the available literature relative to krypton-85 properties, availability, separation and enrichment, and identified applications. In addition, the literature survey also Included a review of the nuclear power Industry. Following
