Corrosion test of irradiated uranium in monoisopropylbiphenyl (RM-171)
The use of organic cooling media for nuclear reactors operating at high power levels predicates the use of a coolant which will not react violently with metallic uranium in the event of a fuel element failure. This report describes the testing, and subsequent examination, of two pieces of irradiated uranium which were immersed in monoisopropylbiphenyl (MIPB) at high temperatures and pressures for periods of time up to twenty-five days. The uranium samples had different irradiation histories and cooling times. Similar experiments had been performed with unirradiated uranium by the Corrosion and Coatings Operation, and it was wished to determine whether irradiated uranium would react with MIPB in a different manner.

Angular Distribution of Photopions From Hydrogen
ABS>An accurate measurement of the differential cross section for the photoproduction of positive pions was made at the Berkeley synchrotron, for photon energies of 280 and 290 Mev. The mesons were produced in a thin-walled liquid hydrogen target, and the meson detection apparatus utilized the characteristic pi -- mu decay of the meson. The measurements were done in two steps, from 0 to 50 deg with equipment specifically designed to reduce a very high positron background, and from 30 to 160 deg with equipment whose efficiency and solid angle could be accurately determined. The experimental results in the small-angle region definitely show the effects of ''photoelectric'' production of pions from the cloud surrounding the nucleon, which are characterized by an abrupt flattening of the cross section in the region forward of 40 deg (c. m.). The results are compared to the theory of photoproduction derived from the dispersion relations, and the sgreement is satisfactory within the limitations of the theory. (auth)

IDP physics primer
In this document it is proposed to describe the plant site and to outline the nature of the pile in order to show the specific design and layout requirements for the production of plutonium by nuclear synthesis. The selection of the plant site involved a number of special considerations. An essential requirement was a large dependable supply of relatively pure water that remains at a fairly low temperature throughout the year. A large source of power was required to circulate the tremendous quantities of water. The potential dangers connected with the high energies of the nuclear reaction and the formation of a large quantity of radioactive by- products required large distances between each operating section of the plant, and between the plant and main rail and highway routes. The plant site layout and reactor areas are discussed in the first part of the chapter, followed by a functional description of the more essential pile components. The chapter concludes with a discussion of reactor instrumentation. 24 figs., 2 tabs.

DIMENSIONAL INSTABILITY OF URANIUM--III. Third Annual Progress Report for June 30, 1957 to June 30, 1958
The mechanism of dimensional instability of uramium is under investigation. Ih order to confirm an assumption of the diffusion theory, the magnitude of diffusion anisatropy in alpha-uranium single crystuls is being determincd by measurement of the self-diffusion coefficients along principal crystullographic directions. lnitial measurements have yielded values of 5 x 10/ sup -15/ cm/sup 2//sec along the (010! and 4 x 10/sup -15/ cm/sup 2/ sec along the (OOl!. These values are being rechecked. in addition, in- -pile experiments designed to further clarify the effect of grain size on growth under irradiation have been initiated.

[Chemistry Thesis] Part 1: The Spectra of Some Aliphatic Aldehydes and Their Monodeutero Derivatives,
BS>An investigation of the infrared and near-ultraviolet spectra of three aliphatic aldchydes and their monodeutero derivatives is described. The infrared spectra of the acetaldehydes (CH/sub 3/CHO and CH/sub 3/CDO) were in agreement with work reported recently. A few new bands are reported and discussed. The infrared spectra of C/sub 2/H/sub 5/CHO, C/sub 2/H/sub 5/CDO, C/ sub 3/H/sub 7/CHO, and C/sub 3/H/sub 7/CDO at 450 to 4000 cm/sup -1/ were observed, and an assignment of the observed bands was made. The weak absorption of the aliphatic aldehydes which extends from lambda 3500 A to lambda 2300 A was investigated. The strength of the absorption (f-value) is decreased by deuterium substitution at the aldehyde CHO group. The decrease in the f-value can be accounted for by the theory of vibrationally induced electronic transitions. The effect of isotopic substitution on the intensity of symmetry- allowed as well as synnmetryforbidden (vibrationally allowed) electronic transitions in polyatomic molecules is discussed. (auth)

Naval Reactors Physics Handbook. Volume 3: The Physics of Intermediate Spectrum Reactors
The present volume has been prepared for persons with some knowledge of the physics of nuclear reactors. It is intended to make available the accumulated physics experience of the Knolls Atomic Power Laboratory in its work on intermediate spectrum reactors. Only those portions have been selected which were deemed to be most useful and significant to other physicists concerned with the problems of reactor design. The volume is divided into four parts which are more or less independent of one another. Part 1 (Chaps. 2--9), Investigation of Reactor Characteristics by Critical Assemblies, reflects the importance of the properties of critical assemblies and of the techniques for obtaining experimental information about such assemblies. Part 2 (Chaps. 10--20), Reactivity Effects Associated with Reactor Operation, details the use of both critical assemblies and reactor theory to make and test predictions of the manner in which the reactivity of an intermediate power reactor will vary during operation. Part 3 (Chaps. 21--26), Heat Generation and Nuclear Materials Problems, considers how reactor heat generation is spread out in space and time, and what nuclear effects result from the presence of beryllium or sodium in the reactor. Part 4 (Chaps. 27--38), Reactor Kinetics and Temperature Coefficients, relates …

Continuous Uranium Monitoring of a Liquid Metal Fuel Reactor. Report to Babcock and Wilcox Co. Atomic Energy Div'
Many types of measurement systems were reviewed for appropriateness of the task of continuous uranium monitoring of a liquid-metal fuel reactor. Of these, the three general classes of neutron methods, x-ray methodss and paramagnetic suseeptibility methods were selected for detailed evaluations primarily for the case of liquid-fuel stream monitoring. In additions the present state of development of electrochemical and spectroscopic methods for application to fused-salt monitoring was assessed. There is no feasible method based on neutron detection that could be made insensitive to fission products in the liquid fuel stream. Methods employing the expected delayed neutron flux as a neutron source show promise of feasibility. Of the several possible methods based on neutron attentuation, one shows promise of feasibility. A method based on irradiation of fuel solution with thermal neutrons and detection of fast neutrons of fission origin appears to have at least marginal feasibility. Liquid fuel monitoring based on x-ray absorption measurement is at best marginally feasible. The spectrum of fission product photons emerging from U-Bi solution may be expected to show structures due to quantum interactions with the constituents of the solutions that might prove applicable to uranium analysis. We recommend that this spectrum be investigated experimentally. Of …

Spallation-Fission Competition in Neptunium Compound Systems. Decay-Scheme Studies
The results of a radiochemical study of fission and spallation products induced in U/sup 234/, U/sup 235/, and U/sup 236 and spallation products induced in U/sup 238/ by deuterons of less than 24 Mev are presented. The (d,n) reactions are interpreted as the result of direct interactions between the deuteron and the target nuclei, while the (d,n) reactions are thought to be taking place primarily by compound-nucleus mechanisms. A method for predicting the peak values of the cross section for (d,xn) and ( alpha ,xn) reactions on uranium and plutonium isotopes is given for x = 2, 3, or 4. The peak-to-valley ratios of the fission-yield curves for U/sup 234, U/sup 235/, U/sup 236/, and U/ sup 238/ bombarded with deuterons of energies of about 23 Mev were studied, and no significant differences were found. Excitation functions for the (d, gamma ) reactions of U/sup 234/, U/sup 236/, and U/sup 238/ rise to a maximum of about a millibarn at a bombarding energy between 15 and 20 Mev. The results of these measurements are seen to be consistent with the excitation functions for (p, gamma ) and ( alpha , gamma ) reactions. The 60minute neptunium activity which had previously …

Nuclear Thermodynamics of the Heaviest Elements. II
The masses of the isotopes of the heaviest elements have been calculated from known decay data in the region, extended by means of decay energies calculated from closed decay-energy cycles and estimated from the systematics of alpha and beta decay energies. The absolute values of the masses are based on the mass-spectrometrically determined mass of Pb{sup 208} and a few measured neutron binding energies. The half-life systematics of alpha decay and spontaneous fission are also presented, and some predictions of the properties of as yet undiscovered nuclides are made.

Small-Scale Instabilites of the Pinch and a Suggested Remedy: The Levitron
Report discussing "experimental results on the classical stabilized pinch," "the usefulness of the Levitron in Stellarator-type operation," and "practical details of the levitation process." A configuration is presented which involves a "toroidal pinch tube inside which a rigid toroidal conductor is levitated by means of an induced magnetic field." Additionally, "an alternative scheme is considered, where the toroidal core is suspended from current-carrying wires, but this approach does not appear promising."
