Various metallographic techniques were employed to determine the best method for the preparation of Al-clad, Ni-plated U fuel elements for bond studies. The quality of the final results and the speed of the preparation were the most important factors to be considered. The procedure presented was found to yield the most advantageous results in the minimum amount of time. (W.L.H.)

This report presents an analysis of the projected economies and processing capacity requirements for a power reactor fuel reprocessing industry based on the recovery of fertile and fissionable materials from presently proposed power reactors within tbe confines of the continental United 8tates for the next five to ten years. An analysis of the present general state of development of a technology required for such an Industry is given. A summary of results of power reactor reprocessing chemical and engineering development at Oak Ridge National Laboratory from July 1955 through December 1956 is given. (auth)
