Available in PDF, EPUB and Kindle. Book excerpt: During recent years, the list of nuclides known to be capable of supporting a chain reaction has substantially increased. Since the criticality aspects for some of these nuclides differ in important respects from those of the most common fissile nuclides, 23592U, and 23994Pu, a new term, ''fissible'' was recently proposed in nuclear engineering to help distinguish differences. Activation energies for fission have been calculated for 41 of the actinide isotopes which are grouped according to four types of nuclides, those with even-Z, even-N, odd-Z, odd-N, odd-Z, even-N, and even-Z, odd-N. With the possible exception of 23792U, all fissible isotopes listed have even N. The activation energy for fission is less in the case of the even-Z, even-N isotopes, but almost without eception it is the odd-N isotopes that undergo fission with thermal neutrons and which constitute the principal criticality problem. This paper reviews the criticality and fissionability aspects of the fissile and fissible actinide isotopes. The criticality of aqueous mixtures of fissile and fissible isotopes also is briefly discussed, including limits for criticality control.

Available in PDF, EPUB and Kindle. Book excerpt: In the last 20 years actinide research has presented unique challenges both for experimentalists and theorists. Their uniqueness stems not only from their nuclear properties, which since the early 1940's have led to their important role in nuclear energy and nuclear technology, but also from their unusual chemical and physical properties which have added new excitement and discoveries to both these disciplines. Containing comprehensive, critical, broad and up to date reviews covering both the physics and chemistry of these exotic elements the Handbook is primarily directed at and a must for those active in the field. It will also be invaluable to those about to enter or marginally interested in this field.

Available in PDF, EPUB and Kindle. Book excerpt: The. first edition of this work appeared almost thirty years ago, when, as we can see in retrospect, the study of the actinide elements was in its first bloom. Although the broad features of the chemistry of the actinide elements were by then quite weil delineated, the treatment of the subject in the first edition was of necessity largely descriptive in nature. A detailed understanding ofthe chemical consequences of the characteristic presence of 5f electrons in most of the members ofthe actinide se ries was still for the future, and many ofthe systematic features ofthe actinide elements were only dimly apprehended. In the past thirty years all this has changed. The application of new spectroscopic techniques, which came into general use during this period, and new theoretical insights, which came from a better understanding of chemical bonding, inorganic chemistry, and solid state phenomena, were among the important factors that led to a great expansion and maturation in actinide element research and a large number of new and important findings. The first edition consisted of aserial description of the individual actinide elements, with a single chapter devoted to the six heaviest elements (lawrencium, the heaviest actinide, was yet to be discovered). Less than 15 % of the text was devoted to a consideration of the systematics of the actinide elements.
