Subsidence of the land surface at Seabrook is due principally to the removal of water. Significant subsidence of the land surface probably began after 1920, and a minimum of about 3.3 feet (1.0 m) and a maximum of about 4.3 feet (1.3 m) of subsidence had occurred at Seabrook by 1973. Probable future subsidence was calculated by two different methods for each of two different loading situations. In the first loading situation, case I, the artesian heads in the Alta Lorna Sand (Rose, 1943) and Evangeline aquifer would continue to decline at the respective rates of 8 feet (2.4 m) per year and 7 feet (2.1 m) per year until 1980 and then cease. In the second loading situation, case II, the artesian heads in the Alta Lorna Sand and Evangeline aquifer would continue to decline at rates of 8 and 7 feet (2.4 and 2.1 m) per year until 1990 and then cease.</p>Land-Surface Subsidence in the Area of Moses Lake Near Texas City, Texas2017-04-27T19:35:53-05:00https://digital.library.unt.edu/ark:/67531/metadc968009/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc968009/"><img alt="Land-Surface Subsidence in the Area of Moses Lake Near Texas City, Texas" title="Land-Surface Subsidence in the Area of Moses Lake Near Texas City, Texas" src="https://digital.library.unt.edu/ark:/67531/metadc968009/small/"/></a></p><p>Abstract: Removal of water, oil, and gas from the subsurface in Harris and Galveston Counties has caused declines in fluid pressures, which in turn have resulted in subsidence of the land surface. Subsidence of the land surface at Moses Lake is due principally to the removal of ground water in adjacent areas. Significant subsidence of the land surface at Moses Lake began after 1900, and as much as 1.8 feet (0.55 meters) of subsidence had occurred in the area by 1973. Probable future subsidence was calculated by two methods for two loading situations. In the first loading situation, case 1, the artesian head in the middle Chicot aquifer, in the Alta Lorna Sand (Rose, 1943), and in the Evangeline aquifer would continue to decline at respective rates of 1, 3, and 3 feet (0.3, 0.9, and 0.9 meters) per year until 1980 and then cease. In the second loading situation, case 2, the artesian head in the middle Chicot aquifer, in the Alta Lorna Sand, and in the Evangeline aquifer would continue to decline at respective rates of 1, 3, and 3 feet (0.3, 0.9, and 0.9 meters) per year until 1990 and then cease.</p>Summary of Some Current and Possible Future Environmental Problems Related to Geology and Hydrology at Memphis, Tennessee2017-04-27T19:35:53-05:00https://digital.library.unt.edu/ark:/67531/metadc968091/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc968091/"><img alt="Summary of Some Current and Possible Future Environmental Problems Related to Geology and Hydrology at Memphis, Tennessee" title="Summary of Some Current and Possible Future Environmental Problems Related to Geology and Hydrology at Memphis, Tennessee" src="https://digital.library.unt.edu/ark:/67531/metadc968091/small/"/></a></p><p>From introduction: This report summarizes information concerning many aspects of the geology and hydrology at Memphis, Tennessee.

Four releases were from elements that contained a xenon tag, which aided considerably in locating three of the elements; data from the fourth element allowed estimation of changes of tag composition with reactor exposure. Rapid release of fission from two breached mixed-oxide elements caused the reactor to trip because of increased delayed-neutron activity, the first time such behavior has been observed. Identification of a subassembly of Mark-1A driver-fuel elements was complicated by multiple failure of its untagged elements during the diagnosis period. Several of these elements had some exposed fuel in the core, which was the likely cause of increasing delayed-neutron signals from the subassembly.</p>Environmental Pollutants and the Urban Economy : Phase 1.

The need for sound economic evaluation of air quality regulations is evidenced by the resistance of many industries to pollution control policies based solely on the technical feasibility of achieving public health-related standards. For many firms that emit air pollutants, the cost of not complying with some regulations is significantly less than the cost of compliance. This final report on the Phase 1 research presents highlights of what has been learned, the mechanisms developed for transferring results to users, a bibliography of documents produced during the project, and a collection of correspondence, articles, and evaluation illuminating the use of project work by others.</p>Three-Dimensional Thermal-Neutron Radiography2015-08-04T08:33:54-05:00https://digital.library.unt.edu/ark:/67531/metadc282918/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc282918/"><img alt="Three-Dimensional Thermal-Neutron Radiography" title="Three-Dimensional Thermal-Neutron Radiography" src="https://digital.library.unt.edu/ark:/67531/metadc282918/small/"/></a></p><p>Three-dimensional radiographic methods provide a means of determining the depth of defect indications and minimizing the confusion that results from overlapping images of structures at various depths in an object. One method of obtaining and displaying three-dimensional radiographic images is multiple-film laminagraphy, i.e., a series of radiographic films taken at different orientations can be viewed superimposed to present a sharply focused image of any desired object plane. Methods that use multiple-film laminagraphy for three-dimensional thermal-neutron images will be described.</p>Cracking and Healing Behavior of UO2 as Related to Pellet-Cladding Mechanical Interaction : Interim Report, July 19762015-08-04T08:33:54-05:00https://digital.library.unt.edu/ark:/67531/metadc282915/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc282915/"><img alt="Cracking and Healing Behavior of UO2 as Related to Pellet-Cladding Mechanical Interaction : Interim Report, July 1976" title="Cracking and Healing Behavior of UO2 as Related to Pellet-Cladding Mechanical Interaction : Interim Report, July 1976" src="https://digital.library.unt.edu/ark:/67531/metadc282915/small/"/></a></p><p>A direct-electrical-heating apparatus has been designed and fabricated to investigate those nuclear-fuel-related phenomena involved in the gap closure-bridging annulus formation mechanism that can be reproduced in an out-of-reactor environment. Prototypic light-water-reactor uranium dioxide fuel-pellet temperature profiles have been generated utilizing high flow rates (approximately 700 liters/min) of helium coolant gas, and a re-circulating system has been fabricated to permit tests of up to 1000 h. Simulated light-water-reactor single- and multiple-thermal-cycle experiments will be conducted on both unclad and ceramic (fused silica) clad uranium dioxide pellet stacks. A laser dilatometer is used to measure pellet dimensional increase continuously during thermal cycling. Acoustic emissions from thermal-gradient cracking have been detected and correlated with crack length and crack area. The acoustic emissions are monitored continuously to provide instantaneous information about thermal-gradient cracking.
