This report addresses the use of radioisotopes for scanning, which has added significantly to the clinician's ability to detect and interpret disease manifestations.

This report addresses he design of a heat pipe-thermionic module concept capable of output potentials as high as 28 volts.

This report covers work performed on the development of an integral adsorption reservoir thermionic converter.

Data on 5Cr - 3Mo - 12Ni alloy, PH13 - 8Mo and Iconel 718 for pressure vessel application are given. The 5Cr - 3Mo - 12Ni posseses characteristics suited to uniform aging of heavy sections. Tensile and toughness properties are good, and structural stability up to 315 deg C is adequate. Weldability with 12Ni - 3Cr - 3Mo filler material is good but 12Ni - 5Cr - 3Mo filler is more efficient. Aging characteristics of PH13 - 8Mo may not be suited to uniform aging of heavy sections. Excellent tensile properties and good toughness can be developed. The alloy is structurally stable at long time heating at 425 deg C. Good weldability with filler metal of matching composition was exhibited but weld ductility and toughness are only fair. (F.S.)

A factorial spark gap detonator study is presented, with the results. UK PETN, (MF 81/10, 6,200 cm{sup 2}/g) at 1.12 g/cm{sup 3} had a higher voltage breakdown and a higher power deposition than others in the test. A somewhat unusual firing system employed for these tests is described. The purpose of the experiment was for determining the effect of specific surface areas (or particle sizes), density, and energy input (including rate of energy input) upon various dependent variables.

The effect of various carrier compounds and methods of preparation of plutonium dioxide upon the spectral emission of trace metallic impurities have been studied. By using an emission spectrometer, equipped with a chart readout, excitation rates have been established for elements analyzed by the carrier distillation technique. This study has shown that the use of 8.3% AgCl-LiF (11:1) in plutonium dioxide gives the most sensitive and reproducable excitation for the majority of impurity elements. By the proper selection of the excitation period for each element, the effect of background radiation is reduced. Spectrometric calibration curves made using data obtained in this study have a relative error of ±30% at the 95% confidence interval.

The 48-inch detonation sphere confined the gaseous products resulting from the discharge of approximately one-half pound (225 g) of an HE (PETN) under investigation. Product analysis, combined with calorimetric measurements will provide data regarding the detonation processes. Results of the initial HE detonation are still in the process of evaluation and tabulation. The final summary of this information will be instrumental in the direction of future experimental endeavor. Investigation at Pantex will be in collaboration with and guided by the research in progress at LRL. A new lid, still in the design stage, must be fabricated to make the detonation sphere compatible with the anticipated need in the testing of future explosives. This will necessitate the modification of the vacuum lines, but the extent of this modification is not known at this time.

The Columbia River Thermal Effects Study is an interagency study being carried out jointly by the Atomic Energy Commission, the Federal Water Pollution Control Administration, and the Bureau of Commercial Fisheries. Leadership for the study as a whole has been assigned to the Northwest Region of the FWPCA. By agreement among the participating agencies, a brief progress report on each project of the study is to be provided each quarter to the FWPCA on a standardized format. The FWPCA consolidates the submissions from all contributors and reissues the combined report to the participating agencies and to the Technical Advisory Committee. This report documents the submissions by Battelle-Northwest staff members to the progress report for the first quarter of 1969. It is expected that the AEC will transmit the submissions by the individual authors to the FWPCA, and that FWPCA will reproduce them in their consolidated report.
