Preliminary data have been obtained on the effect of temperature on the tensile properties of a Pu-0.9 w/o Ga delta stabilized alloy. Contoured castings for tensile specimen fabrication were obtained by pouring in vacuo from 900 {degrees}C into a MgO coated graphite mold heated to 475-500 {degrees}C.

On the basis of the analytical methods used, preliminary radiochemical analysis of the water samples collected after the Salmon event indicate that no detectable level of radioactive contamination exists. Samples were obtained from the calcite caprock at a depth of 934 to 1,006 feet and through intervening aquifers to aquifer 1 at a depth of 365 to 421 feet from the surface. The water sample collected from the calcite caprock was taken within approximately 1,700 feet of the detonation. Periodic sampling of the wells will continue and more refined analytical techniques will be used in analyzing the samples. After the hydrologic test wells have been better developed by bailing, additional isotopes will be investigated.

Abstract: This report presents a summary and brief evaluation of the RFD-2 flight-test data reduced as of December 16, 1964.

Abstract: RFD-2 was the second of Sandia's operational safety flight tests of systems for nuclear auxiliary power.
