Production test-080 - physics tests at D reactor deactivation interim report - experimental data
Production Test-080 authorized the conduct of certain physics tests during the deactivation of D Reactor. The primary objective of the test was to measure certain physics parameters which could be used to check current computational models. In this report are presented a brief chronology of the tests and a tabulation of the experimental data. In general, data processing has not progressed beyond simple reduction of the raw experimental data to a form more easily used in future analytical comparisons and evaluations. Tests included a test for excess reactivity of the reactor by calibration of a control rod, a test for evaluation of experimental technique for measuring the effect of safety systems, tests for data on space-dependent reactor transients, coupling coefficients, etc.

Surficial Geologic Map of Yucca Flat, Nevada Test Site
"The surficial deposits of Yucca Flat, divided into eleven units, are shown at a scale of 1:48,000 (fig. 1A). Major rock types of the bordering bedrock areas are indicated, as are the lithologies of portions of the surficial units. The map explanation (fig. 1B) includes a description of the surficial units."

Recent developments in metallic hydride shielding materials
Declassified 21 Sep 1973. A wide range of metallic hydrides (to NH 9.0), each containing additives to tailor the nuclear characteristics, have been fabricated successfully. Specific additives have included B compounds and high Z- material compounds, e.g., W, Hf, Th. Hydrided Ti which contains B compounds has proven relatively easy to fabricate and has shown excellent radiation stability. Post-irradiation appearance (through 6 x 10/sup 20/ nvt thermal) shows no visible changes. Strengths to 150,000 psi at 380 deg C (with ductile failure) have been observed for TiH. Sound, massive N/sub H/ 6.9 hydrided Zr rods have been fabricated in hydride-furnace batches as large as 50 kg, with 100% yield. A 50 Th-50 Zr hydride of N/sub H/ 6.7 and higher has been fabricated. The basic structure, apparently ThZr/sub 2/H/sub 8/, is a cubic spinel-type structure and is the first reported hydride having this structure. This material, when containing a B compound additive, will probably provide more gamma shielding than is generally needed, but the material has interesting possibilities as a combination breeder-blanket-shield. It now appears that almost any combination of looked-for nuclear properties can be incorporated into a metallic hydride composite having useful engineering characteristics. (16 tables, 23 figs) (DLC)
