Abstract: "This bibliography supplements the information on salt published in U.S. Geological Survey Bulletin 1019-J, "Annotated Bibliography and Index Map of Salt Deposits in the United States," by Walter B. Lang, 1957. The supplement contains additional information on the salt deposits of the United States and of foreign countries, as well as data on the composition, chemistry, geologic occurrences, geophysical exploration, distribution, technology, and production of salt. Additional supplements will be issued from time to time to keep information on these subjects current."

The Armour Dust Fueled Reactor (ADFR)
The A-DFR is based on the use of a fissionable dust carried in a gas. This fuel ferm offers promise of a major economic advance through the use of 2,000 to 3,000 F operating temperatures and a low cost fuel cycle. The development program is described that was initiated to investigate experimentally the proposed fuel and study analytically other reactor characteristics. A brief review of the reactor concept is presented. (W.D.M.)

Continuous Uranium Monitoring of a Liquid Metal Fuel Reactor. Report to Babcock and Wilcox Co. Atomic Energy Div'
Many types of measurement systems were reviewed for appropriateness of the task of continuous uranium monitoring of a liquid-metal fuel reactor. Of these, the three general classes of neutron methods, x-ray methodss and paramagnetic suseeptibility methods were selected for detailed evaluations primarily for the case of liquid-fuel stream monitoring. In additions the present state of development of electrochemical and spectroscopic methods for application to fused-salt monitoring was assessed. There is no feasible method based on neutron detection that could be made insensitive to fission products in the liquid fuel stream. Methods employing the expected delayed neutron flux as a neutron source show promise of feasibility. Of the several possible methods based on neutron attentuation, one shows promise of feasibility. A method based on irradiation of fuel solution with thermal neutrons and detection of fast neutrons of fission origin appears to have at least marginal feasibility. Liquid fuel monitoring based on x-ray absorption measurement is at best marginally feasible. The spectrum of fission product photons emerging from U-Bi solution may be expected to show structures due to quantum interactions with the constituents of the solutions that might prove applicable to uranium analysis. We recommend that this spectrum be investigated experimentally. Of …

Contribution of the wing panels to the forces and moments of supersonic wing-body combinations at combined angles
Report presenting a wind-tunnel investigation at Mach number 1.96 to determine the normal forces, pitching moments, and rolling moments contributed by each wing panel of a cruciform-wing and body combination over a wide range of combined angles of pitch and roll. The wings were triangular of aspect ratio 2 and the body was an ogive-cylinder combination. Results regarding individual panels and panel combinations are provided.

Correlation of Experimental Data With Theory for Perforated Plates With a Triangular Hole Array
The design of the S3G and S4G reactor pressure vessel heads led to a study of perforated plates. A correlation of perforated plate theory with experimental data is given. The test results and analysis used for the S3G model tests are presented along with a review of two other experimental programs in which the experimental data were correlated theory. The conclusions reached indicate that the perforated lattice does, in fact, behave as an equivalent plate of reduced stiffness when subjected to transverse loading. The results obtained from the theory are sufficiently accarate for engineering applications for a range of plate sizes which extends from thin plates (radius-to-thickness ratio 7.5 to 1 for Duncan's tube sheets) to thick plates (radius-to-thickness ratio 1.6 to 1 for the reactor model head) with a variation in the number of penetrations ranging from the large number in Duncan's tube sheet tests down to the relatively small number (19 holes) ia the reactor model head (3/8 scale model).

Differential Voltammetry Using The Hanging Mercury Drop Electrode
"The general techniques of voltammetry with continuously varying potential have been applied to a differential method in which two electrolysis cells are used, each with a hanging mercury drop electrode. Using this method it is possible to determine lO/sup -6/ solutions with increased precision, and it is also possible to analyze solutions as dilute as 10/sup -6/ without removing oxygen from the electrolysis cells. Mixtures can be analyzed easily by adding individual components of the mixture to the reference cell."
