SRP Baseline Hydrogeologic Investigation, Phase 3
The SRP Baseline Hydrogeologic Investigation was implemented for the purpose of updating and improving the knowledge and understanding of the hydrogeologic systems underlying the SRP site. Phase III, which is discussed in this report, includes the drilling of 7 deep coreholes (sites P-24 through P-30) and the installation of 53 observation wells ranging in depth from approximately 50 ft to more than 970 ft below the ground surface. In addition to the collection of geologic cores for lithologic and stratigraphic study, samples were also collected for the determination of physical characteristics of the sediments and for the identification of microorganisms.

Genetic Differentiation of the Geomys Pocket Gopher Complex of Texas
Genetic variation was analyzed for populations of seven taxa comprising four cytotypes of the Geomys bursarius chromosome complex, including G. b. major, G. b. knoxjonesi, and the Edwards Plateau taxa, G. b. llanensis and G. b. texensis. Genetic relationships of the Edwards Plateau gophers with other taxa and between themselves were examined. Genetic similarity, number of fixed allelic differences, and ectoparasite distribution indicate the Edwards Plateau gophers are a distinct gene pool. Isolation of the Edwards Plateau taxa precludes contact zone analysis. However, genetic differentiation is typical of that between other species of Geomys, and the Edwards Plateau taxa should be recognized as G. texensis. Distributions of allelic frequencies indicate little justification in retaining the subspecific status of the Edwards Plateau forms.

Glass mixing theory and tracer study results from the SF-10 run
A general, partial differential equation governing glass mixing in the Slurry Fed Ceramic Melter (SFCM) was derived and a solution obtained based upon certain simplifying assumptions. Tracer studies were then conducted in the SFCM during the SF-10 run to test the theory and characterize glass mixing in this melter. Analysis of the tracer data shows that glass mixing in the SFCM can be explained by use of a model of two, well-mixed tanks in series.

Atomic sputtering in the analytical electron microscope
The advent of UHV medium voltage electron microscopes has brought the microanalyst to a regime of operating conditions in which electron beam induced damage can now be introduced to metallic specimens of medium to high atomic number. We report upon calculations of electron beam induced atomic sputtering which will have bearing upon the next generation of medium voltage analytical electron microscopes. The cross-section calculations reported herein have been completed for all solid elements of the periodic table for incident electron energies up to 1.5 MeV. All computer codes needed to duplicate these computations are available through the EMMPDL. 12 refs., 2 figs., 1 tab.

Steam generator group project: Task 13 final report: Nondestructive examination validation
The Steam Generator Group Project (SGGP) was a multi-task effort using the retired-from-service Surry 2A pressurized water reactor steam generator as a test bed to investigate the reliability and effectiveness of in-service nondestructive eddy current (EC) inspection equipment and procedures. The information developed provided the technical basis for recommendations for improved in- service inspection and tube plugging criteria of steam generators. This report describes the results and analysis from Task 13--NDE Validation. The primary objective of Task 13 was to validate the EC inspection to detect and size tube defects. Additional objectives were to assess the nature and severity of tube degradation from all regions of the generator and to measure the remaining integrity of degraded specimens by burst testing. More than 550 specimens were removed from the generator and included in the validation studies. The bases for selecting the specimens and the methods and procedures used for specimen removal from the generator are reported. Results from metallurgical examinations of these specimens are presented and discussed. These examinations include visual inspection of all specimens to locate and identify tube degradation, metallographic examination of selected specimens to establish defect severity and burst testing of selected specimens to establish the remaining integrity …

The Effect of Remediation on Students Who Have Failed the TEAMS Minimum Competency Test
This qualitative case study provided a narrative portrait of 12 students in the 11th grade in one north Texas district who failed the initial administration of the Texas Educational Assessment of Minimum Skills (TEAMS) exit-level test. It also presented an account of their perceptions of the test and their efforts to overcome this educational hurdle. The following conclusions were drawn from the study. Limited English proficiency (LEP) students had difficulty mastering the language arts section of the test. A majority of the students reported that TEAMS failure had no social impact. Most of the students declined district-offered remediation. Students tended to perceive the test as a personal challenge. Those students who attended remedial tutoring sessions performed better on the following retest than those who declined remediation. Hispanic and Asian students expressed additional study as being the key to passing the test. Black students felt that the key to passing was to spend sufficient time while taking the test. Those students who were more verbal during their interviews tended to be more successul in passing the language arts section of the TEAMS. The following recommendations were made from the study: (a) students who fail the TEAMS by minimal margins should be …

Liquid Phase Methanol LaPorte PDU: Modification, Operation, and Support Studies
To strengthen the data base of the Liquid Phase Methanol LaPorte technology, research is being conducted in parallel with the process development unit engineering and construction efforts. This work will address alternate liquid media studies, effects of CO{sub 2} in CO-rich synthesis gas, optimization of in-situ catalyst reduction and storage, catalyst poison studies, fundamental kinetic modelling, testing alternate commercial catalysts, and field testing of new guard-bed materials for catalyst poisons. Tests will be performed primarily using CO-rich synthesis gas. (VC)

Current cost and performance requirements for residential cool storage systems
This study defines the current cost and performance requirements for residential cool storage technologies based on the characteristics of conventional air conditioning equipment and residential time-of-day (TOD) rate structures existing during the 1986--1987 time frame. Currently, rate structures are changing rapidly. Given the volatility of rate structures, the establishment of cost goal is challenging. The goals presented in this study are based on the utility rate structure as of 1986. This study serves to define residential cool storage cost and performance requirements in the current economic environment as well as the many issues affecting the requirements for residential cool storage systems both now and in the future. The same methodology can be employed to establish long-run goals once future rate structures are adequately defined. 12 refs., 6 figs., 18 tabs.
