MARK VII-A FUEL SLUGS--COMPUTER SURVEILLANCE OF CRYSTALLOGRAPHIC ORIENTATION
Natural uranium fuel slugs are produced by a cortrolled process and definite averages and standard deviations exist for x-ray diffraction data. A change in a production variable, such as heat treatment, is readily discernible through statistical quality control. Programs for the IBM 1401 computer were developed which compute the average values and 3-sigma limits for texture coefficient and G3 growth index data. This information is updated weekly and is plotted by the computer in the form of average (X) and range (R) charts. Each month, an exception report and a G3 index are computed. These show only those charts which had X or R factors exceedirg 3-sigma limits during the month. Thus, trends are revealed in the crystallographic orientation characteristics of fuel slugs. (auth)
