This paper discusses exploration objectives and requirements for a nuclear repository in the U.S.A. The importance of designing the exploration program to meet the system performance objectives is emphasized and some examples of the extent of exploration required before the License Application for Construction Authorization is granted are also discussed.

The technique of hard facing can be a quick and economical means of prolonging wear-life of many metals, but maintenance personnel must first select the proper alloy from the hundred that are available. Even then, roper selection is effective only when it is properly applied by the welder. To complete the successful weld, several hints are offered:

SOME time ago, a firm engaged largely in the manufacture of copper sulphate, applied to me for information as to the practicability of obtaining the copper from their mother liquors by means of electricity ; having reference, more especially, to obtaining the electric current from some magneto-electric or dynamo-electric machine. The mother liquors were the result of several solutions of commercial scrap copper, containing impurities, the quantity of which

Through the remainder of this century, world consumption of fluorine per ton of primary aluminum produced will continue to be substantially reduced. Growth of the primary industry will offset some of the unit consumption, but demand for new fluorine sources will decline sharply. Continued application of dry fume scrubbing systems will be the most significant factor in reducing demand.

In this paper, a numerical model for determining the stress and displacement fields around a crack of arbitrary geometry in a linear elastic medium is described. Accuracy and computational speed were the main considerations in selecting the numerical method and Propagation criteria used to model the growing crack. Some results regarding the stresses and displacements around a two-dimensional crack of arbitrary geometry are discussed.

The use of cast-iron tools, with chilled cutting-edges, for lathes, planers, boring-mills, etc., is not, as Gar as I can learn, very extensive in the United States, or perhaps in England and other parts of Europe. I have, however, no data to guide me in regard to foreign
