Abstract: Three irradiation experiments are described which have been designed to study the behavior of fuel elements in a reactors superheated steam environment. The experiments were conducted in the Superheat Advanced Demonstration Experiment loop, Vallecitos Boiling Water Reactor. The results obtained demonstrated that 304 stainless steel fuel clad in unsatisfactory for use in nuclear super heat fuel sheath designs where plastic strain or plastic deformation is allowed to occur. The results were in agreement with those reported for a previous experiment in SADE (SH-4B) and constituted the basis for change in direction of the superheat fuel program in regard to both design and fuel sheath selection.

Report reviewing literature that concerns "the compatibility of stainless steels and nickel-base alloys with various gases which might be present in or around a high temperature nuclear reactor" (p. 2).

Abstract: The physical property variation of superheated steam differs sufficiently from most other gases to warrant experimental investigation of heat transfer performance. Results are reported here of measurements made in a uniformly heated circular duct with steam at 1000 psi. The data agree very well with the expression use for design purposes, which is based on information in the literature for heating of other gases as well as steam. This work was a continuation of that performed under Task (Heat Transfer) of the Nuclear Superheat Project, AEC Contract AT(04-3)-189, Project Agreement 13.

This report describes the final design of the Fuel Element Rupture Testing Facility and summarizes the safeguards analyses of the design and plans for operation.

"The study of the toxicity of Ra and MsTh(Ra/sup 228/) in humans was continued. Several Thorotrast cases were also examined. Physical and clinical studies were made on 151 persons. In all cases possible gamma ray measurements were made of Ra and MsTh decay products retained in the body, alpha -ray measurements of Rn and Rn/sup 220/ in breath, a complete medical history was taken, a complete x-ray examination was made of the skeleton, and urinalysis, hematological, and blood chemistry studies were made."

Introduction: This is the fourth Quarterly Status Report of work under AEC Contract AT(04-3)-400, held by Stanford University. This contract provides for the construction of the Stanford Linear Accelerator Center (SLAC), a laboratory that will have as its chief instrument a two-mile-long linear electron accelerator.

Report that "describes the equipment, technologies of use, and reliability of an ultrasonic tester - designated UT-4 - capable of detecting very small defects in the brazed closures of reactor fuel elements" (p. 2).

From Introduction : "This analysis partitions the electron density and the electronic pair density of the molecule into components corresponding promoted atomic states, to quasiclassical coulombic interactions of these promoted states, and to interactions resulting from the sharing of electrons between atoms."

From Abstract : "The mass spectrum of leucine-dn, prepared by the reaction of pyridoxal with excess leucine in D2O medium, has been established using the crucible source techniques. ... The reaction can be used for the selective α, β-deuteration of amino acids other than leucine.

From Introduction : "In this paper we describe a choice of normal elliptic integrals which appears to be very well suited for use in integral tables as well as for numerical work."

From report: "In a series of paper (1-3) Sheppard has analyzed the vibrational spectra of simple alkyl halides. During the course of an investigation of the spectra of similar alkyl thiocyanates certain anomalies appeared in the assignments of the CC stretching and methyl rocking vibrations in isopropyl and tert.-butyl halides."

Technical report. From "3. Methods of Preparation" : "Pivadehyde cyanohydrin can be prepared by the reaction of pivadehyde with anhydrous HCN2 or by the sodium bisulfite process. Trimethyllactamide can be prepared by hydrolysis of pivaldehyde cyanohydrin with cold concentrated sulfuric acid. The procedure described here differs in the scale of preparation an in the use of cold fusing hydrochloric acid for hydrolizing the cyanohydrin."

This is a summary report of various technical projects relating to uranium.

Technical report. Form Abstract : "Perchlorate is extracted from aqueous solution by n-butyronitrile as ferrous 1,10-phenanthroline perchlorate. The amount of perchlorate is calculated from spectrophotometric measurement of the absorbance of the extract. Moderate to large amounts of chloride, sulfate, or nitrate cause little or no interference. Chlorate is slightly extracted but the interference can be corrected."

Activities in a program to develop techniques in the use of pulsed neutron sources to measure shutdown parameters related to large thermal power reactors are reported. The experimental work centers around aspects of detecting neutrons in the presence of 10/sup 7/ r/hr gamma fields. Boric acid experiments and Humboldt Bay experiments are reported.

From abstract: "The results of recent measurements on the equations of state of sodium and xenon are discussed. The experimental data for each of these are analyzed to show that the isothermal compressibility is solely a function of volume within experimental accuracy. The basic differences between the low temperature PV relationships for sodium and xenon are shown to be easily understandable in terms of the elementary theories of these substances. The range of experimental pressures (to 20 kbars) and temperatures (20°K to the triple point) is sufficiently great so as to produce significant changes in the lattice thermal properties in each case. These changes are indicated through the use of zero pressure heat capacity data in combination with the equation of state data to calculate the volume and temperature dependence of the Debye Θ. The result is quite spectacular for xenon, where a pressure of 20 kbars roughly doubles ΘD."

Abstract. the direct and inert-gas radiolysis, as well as the vacuum ultra-violet photolysis of CD3CH2CD3, CH3CD2CH3 and C3H2+C3D3 mixtures have been investigated in the presence of radical scavengers. The major conclusions are : (a) at atmospheric pressures, neutral propane decomposition contributes to the observed products although to a lesser extent than parent ion decompositions ; (b) a variation in pressure has a pronounced effect on the fragmentation of the parent ion ; (c) the hydrogen atoms in the ethyl ion are randomized in the direct as well as in the inert-gas sensitized radiolysis ; (d) rearrangement in the parent ion is of minor importance in the radiolysis ; (e) although the formation of propylene is related to the propyl ion, it is not necessarily produced by the neutralization of this ion.
