Reduced waste generation, FY 1986
The United States Department of Energy is committed to the principles of minimizing the quantity and transuranic content of its transuranium (TRU) waste being generated at its nuclear facilities. The reasons are to reduce costs associated with waste handling and disposal, and also to reduce radiation exposure to workers and risk for radionuclide release to man and the environment. The purpose of this document is to provide the USDOE with a plan of research and development tasks for waste minimization, and is prepared so as to provide the maximum impact on volumes based on cost/benefit factors. The document is to be updated annually or as needed to reflect current and future tasks. The Reduced Waste Generation (RWG) tasks encompass a wide range of activities with the principal goals of (1) preventing the generation of waste and (2) converting TRU waste into low-level wastes (LLW) by sorting or decontamination. Concepts for reducing the volume such as in incineration and compaction are considered within the discipline of Reduced Waste Generation, but are considered as somewhat developed technology with only a need for implementation. 33 refs.

Reduction of iron saturation in cosine theta dipoles
A procedure is presented for systematically perturbing the circular iron aperture of a cosine-theta dipole in such a way as to postpone saturation effects up to the point where insufficient iron is present on the midplane. The resulting configuration has little loss in field compared to the alternative procedure of putting a large annulus between the coils and the iron. The necessary saturable iron program used was MDP, but the procedure could be performed with any program. The perturbation functions used to modify the iron shape provide good separation of effects so that only one perturbation per harmonic is needed, thus minimizing the amount of computation required. A coil and aperture configuration with low-field harmonic content approaching the stringent RHIC requirements is presented which requires no b/sub 4/ or higher order correction coils up to 4.1 T, with a good field aperture at low field of 32 mm and at 4.1 T, 30 mm. The b/sub 2/ correction required is largest at an intermediate field, and has a maximum amplitude of about -3.2. The transfer function of the configuration is about 2% higher than that of the reference design.

Reduction of plutonium(IV) using photochemically generated uranium(IV)
The reduction of Pu(IV) using photochemically generated U(IV) has been evaluated as a procedure for possible inclusion in the Savannah River Plant's nuclear fuel reprocessing facility. The ''Purex 2nd Uranium Cycle'' with feed conditions of 400 g/L U, 1 M HNO/sub 3/, and 10/sup -8/ to 10/sup -6/ M Pu was identified previously as the most promising stage for application of a photochemical method. Laboratory tests were conducted under similar conditions to determine if the plutonium could be successfully reduced and separated in a two-phase flowing system. The laboratory scale tests, which used primarily a 0.01 M butanol/0.01 M hydrazine reductant combination, demonstrated that reductive stripping of Pu(IV) using photochemically generated U(IV) is a practical method for removing plutonium from the organic phase. The kinetics of the reductive stripping procedure were found to be determined by the mixing rates of the organic and aqueous phases in this simple laboratory-scale system.

Reevaluation of HFIR source term: Supplement 2
The HFIR source term has been reevaluated to assess the impact of the increase in core lifetime from 15 to 24 days. Calculations were made to determine the nuclide activities of the iodines, noble gases, and other fission products. The results show that there is no significant change in off-site dose due to the increased fuel cycle for the release scenario postulated in ORNL-3573.

Reference waste package environment report
One of three candidate repository sites for high-level radioactive waste packages is located at Yucca Mountain, Nevada, in rhyolitic tuff 700 to 1400 ft above the static water table. Calculations indicate that the package environment will experience a maximum temperature of {similar_to}230{sup 0}C at 9 years after emplacement. For the next 300 years the rock within 1 m of the waste packages will remain dehydrated. Preliminary results suggest that the waste package radiation field will have very little effect on the mechanical properties of the rock. Radiolysis products will have a negligible effect on the rock even after rehydration. Unfractured specimens of repository rock show no change in hydrologic characteristics during repeated dehydration-rehydration cycles. Fractured samples with initially high permeabilities show a striking permeability decrease during dehydration-rehydration cycling, which may be due to fracture healing via deposition of silica. Rock-water interaction studies demonstrate low and benign levels of anions and most cations. The development of sorptive secondary phases such as zeolites and clays suggests that anticipated rock-water interaction may produce beneficial changes in the package environment.

Reflected kinetics model for nuclear space reactor kinetics and control scoping calculations
The objective of this research is to develop a model that offers an alternative to the point kinetics (PK) modelling approach in the analysis of space reactor kinetics and control studies. Modelling effort will focus on the explicit treatment of control drums as reactivity input devices so that the transition to automatic control can be smoothly done. The proposed model is developed for the specific integration of automatic control and the solution of the servo mechanism problem. The integration of the kinetics model with an automatic controller will provide a useful tool for performing space reactor scoping studies for different designs and configurations. Such a tool should prove to be invaluable in the design phase of a space nuclear system from the point of view of kinetics and control limitations.

Regeneration and recycle of spent oxide reduction solvent salts used in pyrochemical plutonium recovery operations at Los Alamos
One method used at Los Alamos for producing plutonium metal is to chemically reduce the oxide with calcium metal in molten CaCl/sub 2/ at 850/sup 0/C. The solvent CaCl/sub 2/ from this reduction step is currently discarded as low-level radioactive waste because it is saturated with the reaction by-product, CaO. We have developed and demonstrated a molten salt technique for rechlorinating the CaO, thereby regenerating the CaCl/sub 2/ and incorporating solvent recycle into the batch PuO/sub 2/ reduction process. We discuss results from salt regeneration and recycle experiments, and present our plans for incorporating the technique into an advanced design for semi-continuous plutonium metal production.

Reinjection Model Studies in Fractured and Homogeneous Geothermal Systems
Reinjection of geothermal waste waters has become an important topic of interest for industry as well as for research. The environmental concerns due to chemical composition of geothermal waste waters had urged the industry to dispose it underground. In several field applications no interference due to thermal front breakthrough was observed on the other hand some cases are reported where reinjection had caused severe declines in energy production due to unexpected breakthrough of injected water. Several analytical and numerical studies are available where the effect of fractures on the movement of thermal front are discussed. It was shown that when the conduction heat transfer from matrix to fracture dominates, retardation of the thermal front movement will be observed. Bodvarsson and Pruess considered the above problem in a five-spot well pattern. They observed as the amount of fluid injected reaches the amount produced, the long-term energy output of the system increases. Pruess in his study compares the behavior of porous medium and fractured medium in terms of pressure decline due to production. Temperature and pressure profiles are presented between an injector and a producer where heating of the injected water in porous medium and in fractured medium with small fracture spacing …

The Relationship Between an Industry Average Beta Coefficient and Price Elasticity of Demand
The price elasticity of demand coefficient for a good or service is a measure of the sensitivity, or responsiveness, of the quantity demanded of a product to changes in the price of that product. The price elasticity of demand coefficients were generated for goods and services in nine different industries for the years 1972 to 1984. A simple linear demand function was employed, using the changes in the Consumer Price Index as a proxy for changes in price and Personal Consumption Expenditures, taken from the National Income and Product Accounts, as a proxy for quantity. Beta measures the sensitivity, or responsiveness, of a stock to the market. An industry average beta coefficient was generated for each of the nine industries over the time period, using the beta coefficients published by Value Line for firms which met certain criteria. In order to test the relationship between the price elasticity of demand and an industry average beta coefficient, a simple regression was performed using the beta coefficient as the dependent variable and the price elasticity of demand coefficient as the independent variable. The results broke down into 3 basic categories: those industries for which there seemed to be no relationship, those industries …

The Relationship Between Domestic Savings and Other Economic Indicators in Korea
This study is an analysis of the relationship between domestic savings and three economic indicators in the Republic of Korea during the 1950s through 1980s. While domestic saving is affected by many economic phenomena, the analysis is confined to national income, exports, and inflation. The study is divided into five chapters. These are entitled (1) Introduction, (2) Domestic Savings, (3) Income and Domestic Savings, (4) Exports and Domestic Savings, (5) Inflation and Domestic Savings. In chapter I, Korea and the Korean economy are introduced, and the scope of the study is stated. Chapter II reviews the related realm of domestic savings: definition, kinds, and determinants of domestic savings. Chapter III presents the relationship between different incomes and domestic savings, and shows non-labor income contributes more powerfully to the formation of domestic savings than labor income. Chapter IV contains effects of exports, and hypothesis testing. The effect of exports suggests that export expansion affects domestic savings positively via an increase in gross national product. Chapter V deals with the correlation between inflation and domestic savings, and its testing. The correlation between inflation and domestic savings is not generally clear except for some specific cases.

The Relationship Between One Aspect of Morality of Young Children and Parental Attitudes Toward Child-Rearing, Gender, Employment Status and Socio-Economic Status
This study examined the relationship between the resistance to temptation of three-, four-, and five-year-old children and parental attitudes toward child-rearing. Other variables explored included gender of the children, employment status of mothers, and socio-economic status of families. Fifty-two three-, four-, and five-year-old children from two centers were tested to determine their levels of resistance to temptation as measured by Grinder's Bean Bag Instrument. Parental attitudes toward child-rearing were measured by Schaefer and Bell's Parental Attitude Research Instrument (PARI). To determine the difference between the resistance to temptation scores and socio-economic status, gender, and employment status of mothers, Jt tests were employed. No significant differences were found with regard to these variables. Factor analysis of the PARI resulted in three primary factors: Hostility-Rejection, Authoritarian- Control, and Democratic-Attitude. To determine the difference between the Hostility-Rejection scores, Authoritarian-Control scores, and Democratic-Attitude scores of the mothers and socio-economic status, _t tests were employed. There were no significant differences between mothers of a lower socio-economic level and their Hostility- Rejection and Democratic-Attitude scores. However, mothers of a lower/upper socio-economic level showed significantly higher levels of Authoritarian-Control than mothers of an upper socio-economic level. To determine the difference between the Hostility-Rejection scores, Authoritarian- Control scores, …

The Relationship of Continuing Professional Education and Pastoral Tenure Among Southern Baptist Pastors
This study examined the relationship between the continuing professional education practices of Southern Baptist pastors and their tenure in their pastoral positions. A survey questionnaire was designed to collect data about the pastors' continuing education and pastoral tenure. A stratified sample of 500 pastors was selected from the 36,235 Southern Baptist churches according to church membership. A total of 217 (43 percent) of the questionnaires was returned and used in the data analysis. Thirty percent of the pastors reported spending no days in continuing education during the past year. Sixty-two percent spent five days or more in continuing professional education. Tenure was not significantly linked to continuing education among the pastors. A personal perception of ministerial competency was positively related to continuing education. The majority of pastors felt accountable to God and themselves in terms of their competency. They strongly resisted any move toward certification or accreditation. The majority of the pastors did not view mobility as an alternative to becoming involved in continuing education. However, the reasons reported for mobility could be interpreted as needs assessment addressed by professional growth. A majority of the pastors strongly agreed that a basic seminary education did not alone prepare a minister for …

The Relationship of Sex and Age at Entrance to School to Second Grade Achievement
This investigation compared achievement of boys and girls in second grade who were seven years old in June, July, and August of 1983 to the boys and girls in second grade who were eight years old in September, October, and November of 1983. The students were tested using the Iowa Test of Basic Skills using the following areas: reading, total math, and composite scores. The study also looked at the correlation of sex and age of students who had been retained in first grade. A comparison of teacher grades to standardized test scores and ability grouping was also presented. One way analysis of variance was applied to the test results. A chi square test of independence was conducted on students retained in the first grade to determine if interaction between sex and age was indicated. Older children scored higher in all three areas measured, while girls scored higher in reading. This may seem contradictory, but is not. Age was significant beyond the .05 level, while sex was significant beyond the .001 level. This difference is explained by the extremes in means for younger boys and older girls. Since first grade curriculum emphasizes reading, this gave girls a definite advantage over …

Relationships Between Selected Musical Aural Discrimination Skills and a Multivariate Measure of Intellectual Skills
This study attempted to explore the strength and nature of relationships between specific intellectual information processing skills included in a multi-dimensional model conceived by Guilford, and measured by Meeker's Structure of Intellect - Learning Abilities Test, and specific musical aural discrimination skills as measured by Gordon's Musical Aptitude Profile. Three research questions were posed, which involved determining the strength and the nature of the relationship between MAP melodic, rhythmic, and aesthetic discrimination abilities and the intellectual information processing skills comprising the SOI - LA. Both instruments were administered to 387 fourth, fifth, and sixth graders from schools in the Dallas area. After a pilot study established the feasibility of the study and reliability estimates of the test instruments, multiple regression analysis determined that 10% to 15% of the variance between intellectual information-processing skills and the individual musical aural discrimination abilities was in common (r = +.32 to r = +.39). It was further determined that only six specific SOI intellectual dimensions, all involving the skills of "Cognition" and "Evaluation", were significantly related to the musical aural discrimination abilities. Through the use of the Coefficient of Partial Correlation, the strength of each individual information-processing skill's unique contribution to that covariance was …
