Abrasive Cutting of Irradiated Uranium

Description: The preparation of radioactive metallurgical specimens for microscopic examination is one of the responsibilities of the Radiometallurgy Sub-Unit. An abrasive cut-off machine development program, based upon a previous experimental model, was undertaken to provide a method for sectioning of irradiated materials without undue personnel exposure or spread of contamination and finally to provide data for the design of an abrasive cutting unit for use in the work cells in the Radiometallurgy Buildin… more

Coulometric Titration Plutonium

Description: Abstract:"A method is described for the electroreduction of plutonium to the +3 valence state in a nitric acid-sulfamic acid solution. Exploratory experiments in the search for a coulometric titration of Pu(III) using electrolytically generated ceric ion are also described. The results strongly indicate that a convenient procedure can be devised. Suggestions for future work are presented."

Reactions of the Hydrated Electron

Description: Abstract. The rate constants for the reaction of the hydrated electron eaq with a number of solutes and with radicals formed in water radiolysis are reported. Hydrated electrons were formed in the electron pulse irradiated solutions at concentrations in the range from 1 to 10 pM. Their reaction was followed by the decay of the optical absorption of eaq at 5780 A. Generally a 04 psec pulse of 15 MeV electrons was used. In the absence of eaq scavengers, second-order kinetics prevailed owing to th… more

Effects of Total Body Z Irradiation of Rats. Part I, Lethal Action of Single, Paired, and Periodic Doses

Description: Abstract: Exposure of Sprague Dawley white rats to single doses of 900 kvp X radiation demonstrated a medium lethal dose of 600 r which was not markedly dependent upon sex, weight, or, in the case of females, stage of the estrous cycle at the time of irradiation. Deaths within 30 days were most frequent between the fourth and eighth, and between the tenth and fifteenth post- irradiation days, indicating the existence of at least two processes leading to death in the "acute" period.

Preliminary Studies for the Separation of HD from H2 by Rectified Absorption

Description: The feasibility of rectified absorption for the recovery and purification of HD from H2 streams has been investigated. The absorbent considered was liquid nitrogen at 78 (degrees) K. The process appears to present no major engineering or operation problems. Cost calculations indicate that the process may be economically competitive with other processes. Process design was based on an estimated separation factor of 1.25 between H2 and HD in this system. Experimental work has been undertaken… more

Monitoring Thermal and Resonance Neutron Flux

Description: The monitoring of thermal and resonance neutron flux in a thermal reactor having high flux over periods of time from 1 to 12 months using think Co foils is considered. Special attention is paid to the many correction factors to be applied to the activation data; neutron temperature, effective cadmium cutoff energy, burnout of Co59 and Co60, and decay of Co60. Results on a homogeneity test of 10 mil, 0.08% Co-A1 alloy foils is given.

Separation of Iron and Tuballoy With Phthallic Acid

Description: Introduction: This report embodies the results of an investigation as to the possibility of removing the bulk of the iron from gunk solutions of various concentrations by precipitation of the iron with phthallic acid and subsequent precipitation of tuballoy. The method consists of dissolving the phthallic acid in the gunk solution and then adding NH₃ to a suitable pH, precipitating the iron, and leaving the tuballoy in solution.

Recovery of Uranium From Contaminated Precipitron Oil

Description: Abstract: The distillation and residue extraction recovery procedures developed for the recovery of uranium from Kinney and diffusion pump oil, were applied to contaminated precipitron oil. The effectiveness and advisability of using the method, in whole or in part, is discussed, and various recommendations for processing this particular type of oil are presented. Additional contaminating substances present in this type of oil added to the complexity of the problem but a satisfactory recovery p… more

Capture of Fast Neutrons by Pb208

Description: From abstract: "Comparison of the activity produced by fast neutrons on lead with other activations corroborates the assignment of the 3.2 hr. activity as Pb209, and the assignment of the reaction as capture of fast neutrons. Two different measurements show that the neutrons captured have energies greater than 100 KEV. This average capture cross section for primary neutrons from 7.5 MEV deuterons on a thick target of beryllium is measured as 10[^]-27 ca[^]2."

Internal Conversion Coefficients of the 2+-0+, E2 Transitions in Even-Even Sm152[over]90 and Gd152[over]88

Description: From abstract: "To investigate the deviation of the internal conversion coefficients of E2 transitions from theoretical computations and their dependence on nuclear deformation, the total internal conversion coefficient of the 121.8-kev 2+-0+ transition in ellipsoidal Sm152[over]90 was measured to be 1.135 ± 0.010 with a high accuracy coincidence-sum method. The K-shell to total internal conversion ratio was determined to be 0.588 ± 0.003 with a [beta] spectrometer...The experiment revealed no … more

Development and Properties of Uranium Monocarbide Cermets : Final Report

Description: Abstract: "Uranium monocarbide-Zircaloy II alloy cermets were developed and tested for chemical and physical properties. It was determined that pure uranium monocarbide can be prepared by vacuum are melting techniques. Following melting, the combination, hot pressing, and corrosion behavior of dense monocarbide has been studied. The preparation of uranium monocarbide-Zircaloy II cermet bodies was investigated by means of hot pressing, cold pressing and sintering, warm pressing, extrusion, and h… more
