About this Item

Three CD-Rom discs in plastic holder. Volume I, References 000-012; Volume II, References 013-075, and Volume III, References 076-195. Plastic holder has some wear and soiling. The discs look almost pristine. Author identified through a bibliographic search. Based on bibliographic research, the compilation prints out at approximately 200 pages. Compilation of critical data obtained from experiments performed in a number of laboratories during the period of 1945 through 1985. It supplements the Nuclear Safety Guide in presenting critical data on which recommendations of the Guide are based. This report gives critical data without safety factors, and is no substitute for the Guide or for the related document, The American National Standard for Nuclear Criticality Safety in Operations with Fissionable Materials Outside Reactors . This standard is supported by publications of H. K. Clark that interpret criticality information for Pu, U-233 and U-235 systems. Information for guiding the safety design of equipment for handling the three common fissile materials appears to a certain extent in the Nuclear Safety Guide, and with greater detail in several handbooks. Other publications specify conditions for unique processes with particular fissionable material. Experiments of several types which contribute results applicable to nuclear design and to safety problems have been described by Callihan. Critical measurements with materials of interest in desired configurations yield information of greatest usefulness and accuracy. In some cases, calculated results are desirable to fill in experimental data or to extend them. Where they appear in the reports, they are identified as calculations because of the uncertainty associated with them. Calculated extensions of experimental data are included to show the nature of trends, not to substitute for results of experiments. They should be used with caution. A fundamental aim of this document is to illustrate relationships among critical data. The compilation and correlation of data for this purpose, from many measurements in a number of laboratories, require a certain amount of normalization or reduction to common terms. Frequently, for example, the effects of variations in geometry or density must be removed to show trends in data.
