Major accomplishments during the first five weeks of this study include: (1) successful adaption of analytical methods; (2) preparation of detailed operational sheets; (3) selection of mines to be sampled, through USGS and various state geologists; and (4) successful completion of coal mine sampling. Complete operational sheets have been prepared which include steps taken from collection of the sample at the mine through counting of that sample for radioactivity. The purpose of these operational sheets is to bring consistency to all the data and traceability of a sample result back through the operational sheets to the mine and day it was sampled.

Typical pyrotechnic reaction exotherms are shown for a number of pyrotechnic blends prepared from Ti hydrides of several hydride compositions. Rate appears to increase with increasing hydrogen in the Ti hydride.

On July 1, 1975, Monsanto Research Corporation was funded by ERDA/DWMT to continue studies at Mound Laboratory with a cyclone incinerator pilot plant for the consolidation of low level radioactive wastes. The report summarizes activities associated with the LSA Cyclone Incinerator Program for the period from July 1, 1975, to June 30, 1976. The document includes work performed in June, 1976, which has not been previously reported. The pilot plant had been installed prior to July 1, 1975, to investigate the feasibility of this method for effectively reducing the volume of LSA wastes. Such a method is badly needed to reduce the costs of transporting such wastes and improving the safety of disposing of them. In addition to using the incinerator to develop parameters for the efficient volume reduction of Mound-generated wastes, the unit is also available for studies to adapt this incinerator concept to the needs of other ERDA sites. The results of such studies then can be used to construct suitable incinerators at these sites.

This report focuses on detectors for the assessment of inhaled heavy radioactive elements. Currently, phoswich detectors are the most prevalent type of detectors in use for assessing lung depositions of heavy element low-energy photon emitters. These detectors, along with their associated instrumentation, have proven their reliability for routine monitoring. Most phoswich detector systems are capable of detecting about one-half lung burden of {sup 238}Pu or about one and one-fourth lung burdens of {sup 239}Pu on an average individual who has a uniform distribution of plutonium in the lungs. Most all the large area NaI detection arrays have been replaced by the phoswich detectors. The NaI detectors are similar in basic characteristic to the phoswich, however, the large area NaI detectors exhibit higher background and sensitivities at the lower energies (< 70 keV) used for assessing inhalation exposures of heavy elements. Some lung counter facilities use proportional counters for assessments. Those in current use have anti-coincidence chambers to reduce background counts and improve the sensitivity. Semiconductor detectors are only practical when used in arrays and, therefore, are the most expensive detection system available.

This pamphlet describes efforts in process mechanization and automation by Monsanto company at Mound laboratory. Remote handling of plutonium, loading pyrotechnic components, automatically scanning air filters, and welding automation are examples of current research efforts at Mound.

This paper provides a configuration description and specifications for the SE-1 detonator. The SE-1 is often referred to as the all purpose detonator due to its popular use as a test unit by the U.S. Department of Defense and ERDA research and development laboratories such as Lawrence Livermore Laboratory, Los Alamos Scientific Laboratory and Sandia Laboratories.

Some solutions to problems of compressing and containing tritium gas to 200 MPa at 700 K are discussed The principal emphasis is on commercial compressors and high-pressure equipment that can be modified easily by the researcher for safe use with tritium. Experience with metal belows and diaphragm compressors has been favorable. Selection of materials, fittings and gauges for high- pressure tritium work also is reviewed briefly.

The objective of this program is to develop and demonstrate separation methods for removing radionuclides from liquid process waste streams. As part of this program, Mound Laboratory will develop lower cost alternatives for use i n1980 fuel reprocessing and waste solidification plants, evaluate the processes within the nuclear fuel cycle which contribute to low-level and intermediate-level waste, and determine the feasibility of ultrafiltration, reverse osmosis, inorganic adsorbents and other separation concepts as additions to process design to reduce the generation of this type of waste. In the initial phase of this program, membrane equipment will be obtained from a commercial membrane manufacturer. After the pilot plant is installed, it will be checked out on cold feed in order to obtain initial flux and rejection data for comparison to data obtained later in the program. After completion of the cold tests, the membrane pilot plant will be run on a combined contaminated feed emanating from showers, laboratory drains, janitorial sinks and decontamination in processing areas, as well as a laundry waste stream containing alpha-contaminated wastes. This combined waste stream contains only alpha contamination (uranium and plutonium). However, as part of this program, gamma activity will be added to the waste stream. …

Mound Laboratory, in its many years of plutonium processing experience, has recovered over 150 kilograms of plutonium-238. Much of this material has been recovered from HEPA filters and other secondary wastes such as sludge, slag, etc. The basic recovery nitric acid leach process at Mound for the decontamination of HEPA filters will be improved and modified i this project for processing filters from the Nuclear Fuel Cycle. Efforts this past quarter were directed toward determining the dissolution parameters of plutonium in HNO{sub 3} which included a study of the optimum acid concentration and optimum dissolution temperature.

Prior to the initiation of this project, considerable literature had appeared in technical journals, particularly geological journals, describing the potential value of the energy contained in hot geopressured waters along the northern Gulf of Mexico coast. The geographic region of interest was identified as the area between Brownsville and Pensacola, approximately 200 miles wide and 750 miles long and therefore containing about 150,000 square miles of surface area. The resource was estimated as lying at depths between 5,000 and 25,000 feet. Although many descriptions of this resource had been written, not much experimental data were available regarding the actual analyses of these waters, especially the methane content. ERDA Geothermal division sponsored the current project to find out the precise analysis of the waters in the geopressured zone in a specific South Louisiana shut in gas well. This information was desired as a prelude to additional resource development projects. If the experimental results of this project were negative, doubts would be raised that there should be serious attempts at other development projects. If the results were positive (i.e., the waters were saturated with methane suggested by hydrogeological theory of this region) then ERDA would feel encouraged to proceed with larger scale …

This is the eighth quarterly technical progress report for a program in which the objective is to evolve and define an accessory drive system that will minimize system power consumption of driven accessories on an internal combustion engine in a passenger automobile. The initial program phases established concept feasibility, determined potential fuel savings, and selected a drive system design for concept mechanization. The current Phase IV carries the program through prototype fabrication and bench, engine, and vehicle tests. The final program objective is a detail drive system design and a demonstrated overall vehicle fuel savings potential. The major technical accomplishments during this reporting period were: the test vehicle was successfully driven to and from Ann Arbor, Michigan from Phoenix with the drive system installed; accessory drive hardware was calibrated, disassembled and reviewed for wear after round trip from Phoenix to Ann Arbor, Michigan; MADS governor performance was analyzed and parameters were varied to demonstrate flexibility available in modifying accessory drive input/output characteristics; and a task list that matched smaller, lower cost accessory components, with the accessory drive equipped vehicle, was prepared. Major emphasis during the remainder of the program will be in this area. (LCL)

A brief review of the small car vs large car fuel economy and emission scenario was conducted to determine whether it is meaningful to implement multi-level emission regulations (different values for small and large cars) to encourage or forces the use of catalytic converters on smaller cars, and by so doing improve the overall fuel economy of the total fleet while at the same time reduce overall emissions. The results of this review showed that: the 1975 to 1976 federal HC standard (1.5 gr/mi) is sufficiently low to effectively force the use of catalysts on larger cars (4000-lb inertia test weight and above) to avoid fuel economy losses, but not sufficiently low to require them on all smaller cars (3500-lb class and below). However, the 1975 to 1976 California HC standard (0.9 gr/mi) is sufficiently low to do so, as evidenced by the fact that essentially all California cars do use catalysts; whether or not small or large cars are equipped with oxidation catalysts, NO/sub x/ standards below the current federal level (3.1 gr/mi) and California level (2 gr/mi) will act to reduce vehicle fuel economy, although small cars are slightly less sensitive in this respect; to meet the projected …

Results obtained from instrumented single-diamond compact cutter experiments, wear and failure mode analysis, and preliminary bit design concepts are described. A model was developed relating rock cutting forces to the independent diamond cutting variables, using a statistical test design and regression analysis. The model was tested with additional independent cutting data and a satisfactory fit obtained. Experiments on two rock types (with compressive strengths of 8 x 10/sup 3/ psi and 21 x 10/sup 3/ psi respectively) were completed and a third has been initiated. Preliminary analysis of single cutter experimental results indicates that optimum rake angles for cutters on an actual bit will be a function of each cutter's engagement (depth of cut). Wear test results on five types of COMPAX/sup R/ diamond compacts continuously cutting sandstone under non-impact conditions are reported. Wear rates for both types were equivalent at high cutting speeds, where thermal effects were thought to be operative. At speeds below approximately 400 sfm, the coarser sintered diamond product was superior. The wear rate of a diamond compact tested on Texas Pink granite was calculated and found to be almost two orders of magnitude greater than the wear rate of the same product as determined by …
