190-H drawdown test

Description: A discrepancy of about 1000 gpm has existed between the full-flow recorded 190, 105 and ROL flows. While past operating practices have not used the 190 or ROL flow rates for official purposes, the disquieting, though not theoretically unexplicable, differences require some quantitative resolution. On November 24, 1962, a drawdown test of the 190-H storage tanks was performed to establish the accuracy of the various flowmeters. The drawdown test of the 190 storage tanks was run at the beginning … more

An Annotated Bibliography on the Effects of Radiation on Heterogeneously Catalyzed Reactions and on Chemisorption

Description: The 264 references were compiled primarily from a search of Chemical Abstracts, Nuclear Science Abstracts, and Dissertation Abstracts through December 1962. The annotations give the type of radiation, the catalysts investigated, and the test reactions used. The entries are cross-referenced, and indexes of the authors, catalysts, reactions, and type of radiation are provided. The compliation is limited to papers in which either heterogeneously catalyzed reactions, chemisorption, or the radiolysi… more

Characteristics of Fuel Compounds and Encapsulation Materials in Radioisotope Heat Sources

Description: The properties of radioisotope fuel compounds and fuel capsule materials which are pertinent to the design and operation of radioisotope heat sources are outlined. These properties are grouped into the following categories: intrinsic, extrinsic, and compatibility. The properties of strontium titanate as the fuel and Hastelloy C as the capsule material are evaluated. (D.L.C.)

Development of a Brazing Process for Seal Blocks

Description: This report covers the development and qualifications of a brazing process capable of forming the bond between the instrument leads and the seal block. The process developed is unusal in that it permits the formation of a bond between austenitic stainless steel surfaces at the temperatures below 1350°F without a flux.

THE EFFECT OF A MINIMUM WEIGHT RADIAL REFLECTOR ON SNAP SHIELDING REQUIREMENTS

Description: A model was derived for a minimum-weight radial reflector for SNAP reactors. The effect, which the use of this optimal reflector has on radiation shield weight requirements is investigated. Weights of systems employing conventional and optimal radial reflectors are compared using the FARSE and FARSER computer codes. It is found that for the configuration under study additional shield weight required when the optimal reflector is used is in excess of the reflector weight savings. (auth)

Effect of Explosive Impacting on Uranium

Description: The tensile and yield strengths of both cast and wrought uranium discs were substantially increased by explosively impacting them at room teraperature and at 375 deg F. However, the room-temperature impacting caused gross damage in the cast material and slight internal damage in the wrought material at the highest impacting pressures. Impacting at 375 deg F, which is just above the brittie-ductile transition temperature for uranium, was the most effective method for increasing the strengths wit… more

EVALUATION OF SURFACE ATTACHED THERMOCOUPLES DURING FORCED CONVECTION HEAT TRANSFER

Description: Metal-clad thermocouples with a flat (spade) tip were used to measure the temperature of a 0.030-in.-thick metal plate acting as a forced convection heat transfer surface. The thermocouples were found to change the temperature of the plate at the point of attachment by 40 percent of the temperature difference between fluid and plate. This value was found to be independent of fluid velocity, heat flux, and fluid temperature. A heat transfer model of the thernrocouple was developed and analyzed t… more

Final report, PT IP-535-C: Test of smaller VSR`s in DR reactor

Description: Because of rod-sticking problems at DR Reactor, a knuckle rod of B Reactor design was installed in vertical safety channel number 28. The substitute VSR, which has a smaller diameter than the original DR rod, has been tested for its operational feasibility including both drop time and reactivity effect. The reactivity effect of the rod was estimated by comparison of the reactivity transient caused by insertion of the specific B-type rod after scramming into the pile, with similar transients cau… more

Increasing the capacity of the Tory II-C Side Support System

Description: The Tory II-C lateral suspension has been designed for 4 g`s of lateral acceleration of the duct. Calculations and model tests indicate that this requirement has been met or exceeded. In order to have a more realistic model to test, Tory II-C springs are going to be fitted around the full scale core slice which was previously built up. Instrumented accelerations of this assembly should give the most direct demonstration that is possible of the response of the system to flight. This memorandum d… more

Isotopic Mass Spectrometry of the Elements

Description: The Analytical Mass Spectrometry Section at Oak Ridge National Laboratory has, for many years, been determining relative isotopic abundances from solid samples. Thus, useful analytical mass spectrometer experience with every pertinent element has been obtained. These include the 55 polyisotopic elements as well as products of irradiation and fission. The techniques used are summarized in this report. A separate page for each element lists preferred compound, loading of sample, manner of obtaini… more

A MANOMETRIC METHOD FOR THE DETERMINATION OF OXYGEN IN ORGANIC COMPOUNDS

Description: A vacuum analytical method for the determination of oxygen in organic compounds was developed. Several milligrams (usually 3 to 5 mg) of the organic to be analyzed are sealed in an evacuated quartz bomb along with 2.5 to 3.5 mg of an organic reducing agent. Next the bomb is fired at 1050-- 1055 deg C for 30 minutes or longer. At the end of the heating period the bomb temperature is rapidly lowered from 1055 deg C to <650 deg C. As a last step the gaseous products are removed from the bomb and t… more
