Self-Shielding Measurements in PPA-20

From Introduction: "The self-shielding characteristics of a number of absorbers and of U-235 and U-238 have been investigated in PPA-20 (66°). Most of the measurements have been made in Ring 3 at the core mid-plane. The foil doubling technique was employed. Particular attention was given to 'thin' foil regions for the purpose of extrapolating the data to zero thickness."

Use of 1-Ascorbic Acid as a Colorimetric Reagent for Uranium (open access)

Use of 1-Ascorbic Acid as a Colorimetric Reagent for Uranium

Abstract: "Hexavalent uranium in weakly acid solution produces with a large excess of ascorbic acid a yellow-brown color whose intensity under certain conditions is a linear function of uranium concentration. Chloride, nitrate, perchlorate, along with Fe, Cd, Mn, Na, Ca, Sn, Mg and Th are without effect on the color while phosphate, sulfate, fluoride, citrate, tartrate, oxalate, chromium, and vanadium and moderate amounts of Ni, Zn, Mo and Al interfere. A rapid ether extraction procedure for purification of the uranium has been developed."

The Detection of Uranium by X-ray Spectrometry (open access)

The Detection of Uranium by X-ray Spectrometry

Abstract: "The possibility of detecting small quantities of uranium with an X-ray spectrometer was investigated. An X-ray spectrograph was modified by substituting a geiger counter for the photographic film. Both primary and secondary methods of excitation were studied. Radiation background of high intensity and variability limits the sensitivity of the present apparatus to 1%. Suggestions are made for increasing the sensitivity of the method."
