ANNUAL SUMMARY RESEARCH REPORT IN CHEMISTRY, JULY 1, 1959-JUNE 30, 1960

Description: Pilot-plant work on ion exchange separation of rare earths indicates that elution with HEDTA on hydrogen-form resin should conserve Sc. Then, after Sc, Lu, Yb, Tm, and Er are diverted to an auxiliary bed, the remaining rare earths can be resolved with EDTA. Data from investigations of rare-earth glycolate solubilities at 20 and 60 deg C are tabulated. In other work, the effectiveness of glycolic acid for fractionally precipitating rare earths was investigated, and the solubilities and compositi… more

Appendix: Production Test IP-353-A, rapid depressurization of a KER loop

Description: Proposed fuel element loading and operating conditions for this test are tabulated. The loading is designed to provide high tube power and near-maximum-allowable coolant outlet temperature, accompanied by low fuel surface heat fluxes. Conditions which would exist during the proposed test were compared with those during the rapid depressurization incident in KER-2 on Jan. 31, 1960.

CERENKOV AND SCINTILLATION PROPERTIES OF PLEXIGLAS UVT AND UVA

Description: The scintillation and Cherenkov properties of UVA (ultraviolet absorbing) and UVT (ultraviolet transmitting) Plexiglas specimens were tested by analyzing cosmic-rayinduced pulses traversing the materials. It was found that the UVT sample has less than 1/6 the scintillation effect of UVA and is preferred for use in counters. (J.R.D.)

A COMPENDIUM OF INFORMATION FOR USE IN CONTROLLING RADIATION EMERGENCIES INCLUDING LECTURE NOTES FROM A TRAINING SESSION AT IDAHO FALLS, IDAHO, FEBRUARY 12-14, 1958

Description: A training course was held to familiarize members of radiological assistance teams from various parts of the U. S. with the origin and nature of situations that might, by the event of an unusual accident. release radioactive materials to a populated environment. The course consisted of a series of lectures and a tour of some of the radiation monitoring, source handling, and transportation facilities at NRTS. A summary of the lecture material is presented.

The Complete Bound Spectrum Of The Negative Hydrogen Ion

Description: Ever since the existence of a bound state of Hydrogen was discovered, it has been uncertain whether any other bound states existed. In addition to its importance in astrophysics this question has also come up in discussions of the scattering of electrons from hydrogen. To settle this problem it is necessary to calculate lower bounds for the eigenvalues of the Schrodinger equation. A simple calculation has been carried out for the problem of the negative hydrogen ion.

Dynamic Rock Mechanics Investigations Final Report, Project Cowboy

Description: Strain gage instrumentation is reported of three Cowboy shots to measure the strain produced in salt by coupled and decoupled detonations. Linear array tests were made to develop a propagation law for strain, to determine particle velocity and acceleration in salt, to compare explosives, to determine the effect of impedance coupling between explosive and rock, and to investigate other seismic effects. Crater tests were made to determine the dynamic tensile breaking strength of salt. Tests were … more

EVALUATION OF THE ZEROS OF CROSS-PRODUCT BESSEL FUNCTIONS

Description: Computational results for the characteristic values and solutions of Bessel's equation are presented. Specifically, the results pertain to the first two solutions subject to the Neumann boundary condition at r = a,b and to the first solution subject to the Dirichlet condition, when (b-a)/(b+a) is small (0.1, 0.01, and 0.001). Approximate analytic formulas are derived to complement the computational results. The possible application of the data to phenomena involving the interaction of an intens… more

Description: Forced-convection heat transfer to superheated steam in turbulent flow was experimentally investigated, utilizing two-channel geometries: a round tube, 0.333-in. ID by 12.00 in., and a thin rectangular channel, 0.047-in. wide, aspect ratio, 26.6: 1, and 12.00 in. in length. The experiments encompassed a Reynolds number range from 20,000 to 370,000, pressure range from 300 to 1500 psia, inlet superheat from 5 to 160 deg F, and film temperature differences from 30 to 550 deg F.
