In a prevlous paper, some inequalities occurring in the one-veloclty theory of neutron transport with lsotropic scattering were derived. Some of the previous results are generalized to the case of linearly anisotropic scattering. (auth)

Reference (2) requested that we review the possibilities that classified information might be revealed by isotopic composition of fission products, and suggest methods of making any such compositions. These questions have been reviewed thoroughly by Hanford Laboratories experts; their analysis confirms earlier conclusions (Reference 1). Based on current classification guides, isotopic compositions of cesium, promethium, and probably other rate earths could reveal secret information. Unless classification rules are changed, we see no way to declassify these fission products except by blending them with unclassified products from other sources.

Approximately 285 ribbed aluminum process tubes will have been installed in the central zone of each K reactor on completion of the zirconium tube replacement program. This report recommends the use of mixer fuel elements in the ribbed tube and discusses the basis for the recommendation. The recommendation is complicated by the fact that two tube designs having different dimensions will be used and the optimum mixer location for the two tube designs is different also.

The differential cross sections for elastic scattering of 14-Mev neutrons from nitrogen and oxygen were measured in the angular range from 17 to 140 deg , using liquid targets and annular ring geometry. Inelastic scattering to the 2.31 and 3.95-Mev levels in N/sup 14/ and to the levels near 6 and 7 Mev in O/sup 16/ was investigated over a more restricted angular range. The 2.31-Mev level in N/sup 14/ was not excited appreciably, in disagreement with previously reported results. For both elements, the elastic scattering cross sections (determined to an accuracy of 10%) were found to be appreciably higher than the optical model predictions by Rjorklund and Fernbach for scatterirg angles larger than 70 deg . The inelastic cross sections measured are, within experimental accuracy, the same as the corresponding (p,p') cross sections. (auth)

The stability of the circulating beam in a radiofrequency system with large beam loading is investigated. The results are applied to the 3-Bev electron-positron storage ring under design at the Cambridge Electron Accelerator. It is found that for this type of system, in which there are no large transients, it should be possible to use most of the radiofrequency power to supply the radiation losses of the circulating beam and only dissipate a small fraction of the power in the r-f cavities.

The initial 30-Mw SRE Core III loading will contain a total of 33 fuel elements. Of these, the central 7 fuel elements are test elements and the remaining 26 are driver elements; 4 of the 7 test elements are designated as standard test elements. These elements are identical to the driver elements with the exception of the active fuel length. The remaining 3 test elements are designated as special test elements and incorporate fuel rods of smaller diameter and increased enrichment to obtain higher burnup rates, greater specific power, and higher fuel temperatures. Geometry design data for the various elements considered in the analysis was obtained from Dwg. No. 650 deg F, the mixed-mean coolant outlet temperature for the core at 1200 deg F ( plus or minus 15 deg F), the maximum average temperature on the cladding at 1275 deg F, and the maximum fuel temperature in the range of 2000 to 2100 deg F. The thermal performance of the fuel elements was analyzed with the SORTD code and the Heating code. The results of the analysis are presented in tabular form. Axial temperature profiles are also presented for representative fuel elements. The core outlet coolant mixed-mean temperature was …

From introduction: "Following the USSR announcement of its intention to resume testing, arrangements were made for the three stations collecting individual rainfall samples to begin analyses for short-lived nuclides. Some of the data are now available and are reported here." From Data: "The available data, including samples for Houston, Texas and Louisville, Kentucky are given in the tables at the end of this report."

Criminal intelligence report by detective W. S. Biggio which states that a source thought that Mrs. Ruth Paine's maiden name was Hidell, a surname used as a cover up by Lee Harvey Oswald.
