From Introduction: "The work of the Magnetic Measurements Section of the National Bureau of Standards includes (1) testing of specifically prepared test specimens intended for use as standards for checking magnetic testing apparatus (2) investigation and development of magnetic testing apparatus (3) calibration of mutual inductors, test coils, and instruments for measuring magnetic fields, and (4) investigations in the field of magnetics such as studies of phenomena associated with nuclear magnetic resonance or the selection and testing of materials suitable to be used as standards of magnetic susceptibility."

We present the results of measurements of the angular distribution of fission fragments produced by irradiation of Au{sup 197} and Bi{sup 209} with various heavy ions. The projectiles, B{sup 11}, C{sup 12}, N{sup 14}, and O{sup 16}, had energies from a few MeV above the Coulomb barrier to 10.4 MeV per nucleon. The gross features of these results can be explained by use of a model and parameters that have been used by others to account for angular distributions of fission fragments from helium-ion bombardments. In detail, however, these results appear to indicate that the models used to predict the average value of the angular momentum of the compound nucleus give values too low near the Coulomb barrier. Furthermore, at high bombarding energies it is necessary to consider the fact that appreciable direct interaction is taking place.

During the past four years, IBM data processing computers have been utilized to perform countless studies involving the optimization of the HAPO plutonium production complex (RA.PO and off-site supporting plants). During this time, three process optimization models have been constructed and associated Fortran programs have been written. These three are (1) maximum net return, (2) minimum reactor unit cost, and (3) maximum grams. This document will be concerned only with the first program: net return optimization. In January of 1960, a new program was written for the IBM EDPM 709. This new program incorporated the desirable features of the previous programs and provided additional output data. During the two years since January, 1960, the net return optimization program has undergone many changes. These changes have been caused by improvements in the process technology and a major change in the definition of the Pu-240 specification. It is the purpose of this document to describe the current version of the net return optimization program.

For approximately the past two years, alloyed dingot uranium has been irradiated on a production scale for evaluation of rupture performance relative to ingot uranium. Supplementary data on dimensional behavior and certain pre-irradiation measurements have been accumulated under the Quality Certification Program. This report presents a comparison of ingot and dingot performance based on data obtained to date from this testing program. The discussion consists of three sections: (I) dimensional stability, (II) external bond quality, and (III) reactor rupture performance.

"Progress is reported on Phase II of a program for the development of a mixed fission product fueled thermoelectric generator. Materials studies are described in which bonded assemblies of bismuth telluride were life tested up to 3000 hours at 350 to 400 deg F hot junction temperature. Data were too inconsistent to define any satisfactory long-life bonding process. Further work is needed to eliminate the process variables. Insulation studies aimed at determining the thermal conductivity of various insulations with different fill gases under reduced pressures are described. Opacified aerogel powder appears to be very promising as an insulation medium for a diffuse heat source. A full- scale simulated test generator aimed at proving out the concept of a diffuse heat source for power generation is described. Progress on the construction of this electrically heated generator and its thermoelectric power converter is related.
