HECT II Compressor Pressure Drop Test

Description: In applications where more than one HECT II compressor is used in a loop, in either parallel or series arrangement, it becomes important to know the pressure drop across an inoperative compressor for both the "turbine stationary" and the "turbine free" conditions over a considerable flow range of the flowing medium. This report contains the results of pressure drop tests conducted with air at 14.7 psia and 80 degrees F.

Measured Circulation Rates in the HRT

Description: This report details circulation rate calculations for the fuel and blanket high-pressure systems using measured pressure drops across heat exchangers at the Oak Ridge National Laboratory. Accurate values for flow rates through the core and blanket are important in the analysis of reactor operation and solution behavior.

Summary of HRT Run 19

Description: This report details damage and impacts to operations and maintenance resulting from failures of the blanket circulating pump and fuel circulating pump at the Oak Ridge National Laboratory during a startup on February 5, 1959. The reactor was critical for 18 hours.

Fission Product Transport Through Graphite Matrices

Description: The transport of fission products from points of origin in unclad graphite matrix-types fuels to the reactor circulating system involves, as one of the steps, diffusion through the graphite matrix to the fuel element surface. An important problem is the determination of the effective transport rates of the various mobile elements (e.g., Xe, Kr, I, Br, Cs, Rb, and Te) and their daughter products of interest (Sr, La, Ba, Ca, Nb, Y and Te) through various graphites suitable for use as fuel elemen… more

Studies of Surface Contamination: 1. Intercomparison of Methods for Measuring "Removable" Contamination.

Description: The purpose of this study is to evaluate the smear and adhesive paper techniques for measuring [radioactive] surface contamination, and to compare these with a new method of sample collection. This third sampling procedure employs air impingement to redisperse loose contamination from the surface and the resulting airborne material then is collected on a filter.

Chemical Development Section C Progress Report for October-November 1960

Description: Studies are being made on the recovery of thorium (and uranium) from granitic rock, since this source represents a very large potential thorium reserve for the nuclear power industry. In preliminary leaching studies on 16 granite samples (containing 8-95 ppm thorium and 1.5-16 ppm uranium), maximum recoveries of thorium and uranium ranged 30-85% and 15-65% respectively, and sulfuric acid consumption was high (30-120 lbs H2SO4 per ton of granite). A relatively high acidity was needed to obtain r… more

Erosion Experiments of Powder Compacted Uranium Dioxide Under Dynamic Steam Flow (Preliminary Report)

Description: Experiments were carried out to determine the erosion, oxidation and dimensional characteristics of purposely defected fuel elements containing unsintered UO2 powder prepared by the swaging technique. The experiments were conducted in an out-of-reactor loop under superheat conditions of pressure, temperature, flow velocity and steam chemical composition.

Hydrides Of Germanium, Tin, Arsenic And Antimony

Description: Volatile hydrides may be prepared from ether solutions by the reaction of the appropriate chlorides with lithium hydroaluminate. In this general method, it is necessary to work with strictly anhydrous reagents and solvents because of the great reactivity of lithium hydroaluminate toward water. The procedures described here are believed to be much more convenient because the reducing agent employed is potassium hydroborate, which is relatively insensitive toward water. Since only aqueous solutio… more

Fast Pulse-Amplitude Discriminators

Description: Pulse-amplitude discriminators are useful in nuclear counting to separate signals of greater amplitude from a background of unwanted or noise signals of lesser amplitude. As used here, the term "fast" implies circuits capable of responding to pulses between a nanosecond and a microsecond in duration. An ideal discriminator would produce for any incoming signal whose amplitude is greater than a threshold bias level, an output pulse of constant amplitude, duration, and delay with respect to the i… more
