Abstract: Mine mapping of the tyuyamunite-type deposits In the Salt Wash member of the Jurassic Morrison formation of the Lukachukai Mountains, Apache County, Arizona revealed recognizable spatial relationships between ore mineralization and: fractured areas, sedimentary features, and interstitial carbonate.

Equations for the quantity of thorium daughters on an air sampler after various times of collection and decay are derived and evaluated. The most limiting assumption is the constant concentration over the sampling period. Applications of these equations to measurement of decay curves, alpha energy analysis and the simultaneous solution involving measurements at the three decay times are discussed.

The design of the Purex Off-Gas Treatment Facility requires the use of new dissolver off-gas jets which will be installed in series with present jets in the Purex in-canyon "donut" jumpers. When the new jets are placed in operation, the motive air and steam supply services to the in-canyon jets will no longer be required and the in-canyon jets will become flow restrictions in the dissolver off-gas train. Calculated values of pressure drop across these "dead" jets at maximum off-gas rate varied from about 18 to 7 inches of water depending on whether the dead jets were considered as sharp-edged orefices or venturi meters without downstream pressure recovery. In the preparation of process specifications for hets for the new facility, accurate values for the pressure drcp introduced by the dead jets were required to avoid oversizing the new jets with resultant waster of motive jet fluid.

A centerless-ground, 0.25-in.-diam. by 0.75-in.-long sapphire single crystal exposed to an integrated thermal neutron flux of 2 x 10 19 nvt at a temperature of 350 deg C (660 deg F) did not change its dimensions appreciably simple beam, with slightly less force than was required to break a similar unirradiated rod. In a darkened room the irradiated sapphire begins to thermoluminesce noticeably at 280 deg C (535 deg F) and most of the amber or brown coloration produced by the pile exposure is retained after annealing for 24 hr at the pile exposure temperature of 350 deg C (660 deg F).

The essential physical and mechanical properties of materials which enter into the design considerations of high-temperature systems have been outlined, and the relationship of these factors to the detailed design of structural members noted. Particular attention is given to the phenomenon of strain-cycling and relaxation, and several engineering devices wherein these effects can markedly influence design are mentioned. Techniques and apparatus for the measurement of strain-cycling and relaxation properties are described and some recent data for Inconel at 1500 F is reported. A brief discussion is presented on design-criterial for high-temperature applications, and it is pointed out that in some high performance devices the considerations of the strain-cycling phenomenon may impose the design philosophy of "steady-state" operation. Some elementary applications of strain cycling data to design are described, and test experience indicates that analytical techniques can be developed for predicting with reasonable reliability of the fatigue life of structures.
