Variable metric method for minimization. [In FORTRAN for IBM 704]

Description: A method for determining numerically local minima of differentiable functions of several variables is described. In the process of locating each minimum, a matrix which characterizes the behavior of the function about the minimum is determined. For a region in which the function depends quadratically on the variables, no more than N iterations are required, where N is the number of variables. By suitable choice of starting values and without modification of the procedure, linear constraints can… more

Sample calculation -- GVR values for determining tritium separations costs

Description: This paper shows the calculations for the Gas Volume Ratio, defined as the Total Gas Volume/Target Volume. Using 20 tons of LiAlO{sub 2} as the target, 5028 cubic feet of tritium, protium, and helium are produced. The target volume equals 312.5 cubic feet of aluminate, so that the GVR = 5028/312.5 = 16.1.

Interlaboratory Neutron Flux Spectral Measurement Program

Description: This report details an interlaboratory cooperative study undertaken on neutron flux spectral measurements, calculations, and data correlation for reactor irradiation and physics study by various sites. The Testing portion of this study was the irradiation of a wide variety of flux monitors in a special snout capsule holder. The attached sketch shows the capsule holder design, facility design, and the capsule position in relation to adjacent process tubes. A summary of the irradiations performed… more
