1964 Project Springfield studies. Research Report 2. [Stratospheric-tropospheric exchange of fallout particles and subsequent rainout of radioactive particles by precipitation systems]
The analysis of the data for a storm on April 4, 1964, showed that in spite of all efforts to obtain a dynamically and internally consistent three-dimensional analysis of conventional wind, pressure, and temperature data, there remain ambiguities of 50 to 100 miles in the horizontal location of the boundaries of the stratospheric air. Missing wind data and temperature errors, though not disastrous in routine meteorological analysis, can seriously affect the potential vorticity computations for several isentropic surfaces. Trajectory analyses introduce additional errors. Aircraft measurements of fallout beta activity, when carefully planned and made at map time, can improve the precision to 1000 feet in the vertical, and to a few miles in the horizontal. This precision is necessary for conclusive proof of the capture of radioactive particles from the stratosphere by precipitating clouds. However, for large-scale global studies of fallout transport, errors of 50 to 100 miles in the location of air parcels with certain potential. During the 1963 study, it was found that the flow patterns at different levels were seriously affected by coding and plotting errors in the radiosonde data which often escape attention in conventional upper air analyses.

Advances in stainless steel welding for elevated temperature service
An extensive program to characterize the microstructures and determine the mechanical properties of stainless steel welds is described. The amount, size, shape, and general distribution of ferrite in the weld metal was studied. The effects of electrode coatings on creep-rupture properties were determined as were the influences of slight differences in analyzed contents of carbon, silicon, phosphorus, sulfur, and boron. Using the above information, a superior commercially produced electrode was formulated which took advantage of chemical control over boron, titanium, and phosphorus. This electrode produced deposits exhibiting superior mechanical properties and it was successfully utilized to fabricate a large nuclear reactor vessel. (auth)

Analysis of Tritium Releases to the Atmosphere by a Ctr
Removal by atmospheric processes of routinely and accidentally released tritium from a controlled thermonuclear reactor (CTR) was investigated. Based on previous studies, the assumed form of the tritium for this analysis was HTO, or tritiated water vapor. Assuming a CTR operation in Morris, Illinois, surface water and ground-level air concentration values of tritium were computed for three space (or time) scales: local (50 Km of a plant), regional (up to 1000 Km of the plant), and global.

Analytic transport theory solutions for steady sources in pure absorbers
The monoenergetic steady-state integral neutron transport equation is solved analytically for several simple source configurations for pure absorbers. Specifically, the scalar neutron flux, phi(r), is derived for configurations in cartesian geometry representing the point, infinite line, infinite plane, finite line, infinite ribbon, finite ribbon, infinite tube, and finite box sources. Some of these configurations (point, infinite line, and infinite ribbon sources) were investigated previously by Case, deHoffmann and Placzek and are reviewed here for completeness. The others are more complex and represent new analytic solutions against which multidimensional numerical transport calculational codes may be tested. (auth)

Analytical methods for fissionable materials in the nuclear fuel cycle. Covering June 1974--June 1975
Research progress is reported on method development for the dissolution of difficult-to-dissolve materials, the automated analysis of plutonium and uranium, the preparation of plutonium materials for the Safeguard Analytical Laboratory Evaluation (SALE) Program, and the analysis of HTGR fuel and SALE uranium materials. The previously developed Teflon-container, metal-shell apparatus was applied to the dissolution of various nuclear materials. Gas-- solid reactions, mainly using chlorine at elevated temperatures, are promising for separating uranium from refractory compounds. An automated spectrophotometer designed for determining plutonium and uranium was tested successfully. Procedures were developed for this instrument to analyze uranium--plutonium mixtures and the effects of diverse ions upon the analysis of plutonium and uranium were further established. A versatile apparatus was assembled to develop electrotitrimetric methods that will serve as the basis for precise automated determinations of plutonium. Plutonium materials prepared for the Safeguard Analytical Laboratory Evaluation (SALE) Program were plutonium oxide, uranium-- plutonium mixed oxide, and plutonium metal. Improvements were made in the methods used for determining uranium in HTGR fuel materials and SALE uranium materials. Plutonium metal samples were prepared, characterized, and distributed, and half-life measurements were in progress as part of an inter-ERDA- laboratory program to measure accurately the half-lives of …

Anode sputtering characteristics of the Berkeley 2.5 MV source
An investigation was made of a number of parameters affecting the performance of the SuperHILAC 2.5 MV Adam injector source. The description will emphasize anode sputtered materials, and will discuss in some detail calcium and gold ion production. Parameters varied include electrode geometry, support gas type and electrode bias, to optimize beam intensity and electrode consumption. A factor of three improvement with high n$sup +$ gold ions appears evident with a new displaced electrode geometry. The source is operated in cold mode, is pulsed and operates usually at less than 0.6 amperes average current. Under these conditions source life has been measured to be sixteen hours at 25 percent duty factor when generating calcium ions with neon support gas. (auth)

Application of Soft X-Ray Appearance Potential Spectroscopy to Light Lanthanides, 4d Transition Metals, and Insulators
Evaporated films of La, Ce, Yb, Y, Ag--Mn(5 percent), KCl, MnF$sub 2$, CsCl and LaF$sub 3$ were studied using the soft x-ray appearance potential spectroscopy (SXAPS) technique. Studies were also made of bulk polycrystalline samples of Y, Zr, Nb, and Mo. The results are discussed in terms of existing SXAPS theories. Several similarities between soft x-ray absorption (SXA) data and the SXAPS results are discussed, and it is shown that the SXA data can aid in the interpretation of SXAPS spectra when using the well-known self-convolution model. In this approximation the absorption coefficient, $alpha$(E), is substituted for the density of states, N(E-E/sub c/) $Yields$ $alpha$(E). For more localized excitations, a convolution of $alpha$(E) with bremsstrahlung isochromat data, based on Wendin's two density of states formalism is used to predict SNAPS results. (auth)

Application of stress corrosion to geothermal reservoirs
There are several alternative equations which describe slow crack growth by stress corrosion. Presently available data suggest that an alternative form may be preferable to the form which is most often used, but the issue cannot be clearly decided. Presently available stress corrosion data on glasses and ceramics suggest that rocks in a proposed geothermal reservoir will crack readily over long time periods, thus seriously limiting the operation of this type of power source. However, in situ hydrofracturing measurements together with a theoretical treatment suggest that such a reservoir will contain a relatively high pressure over a long period of time without further cracking. Further experimentation is desirable to measure directly the critical stresses for crack growth rates on the order of 10/sup -7/ m/sec.

Attributes of system testing which promote cost-effectiveness
A brief overview of conventional EMP testing activity examines attributes of overall systems tests which promote cost-effectiveness. The general framework represents an EMP-oriented systems test as a portion of a planned program to design, produce, and field system elements. As such, all so- called system tests should play appropriate cost-effective roles in this program, and the objective here is to disclose such roles. The intrinsic worth of such tests depends not only upon placing proper values on the outcomes, but also upon the possible eventual consequences of not doing tests. A relative worth measure is required. Attributes of EMP system testing over the range of potential activity which encompasses research and development, production, field handling, verification, evaluation, and others are reviewed and examined. Thus, the relative worth, in a cost-effective sense, is provided by relating such attributes to the overall program objectives so that values can be placed on the outcomes for tradeoff purposes.

Basics of Bayesian reliability estimation from attribute test data
The basic notions of Bayesian reliability estimation from attribute lifetest data are presented in an introductory and expository manner. Both Bayesian point and interval estimates of the probability of surviving the lifetest, the reliability, are discussed. The necessary formulas are simply stated, and examples are given to illustrate their use. In particular, a binomial model in conjunction with a beta prior model is considered. Particular attention is given to the procedure for selecting an appropriate prior model in practice. Empirical Bayes point and interval estimates of reliability are discussed and examples are given. 7 figures, 2 tables (auth)
