S>Bond strength of diffusion and adhesive bonds has long remained one of the unsolved problems facing the materials testing industry. Many techniques are available for the detection of unbonds but these tend to become inaccurate when the unbonded surfaces are in intimate contact. Weak bonds in almost all cases cannot be distinguished from bends which approach base material strengths. One must usually resort to destructive testing of samples cut from production parts to obtain bond strength information. This is not the most satisfactory method from a cost and reliabilily standpoint. The accuracy of this data is also in some doubt since the cutting procedure itself may disturb the bond and the residual stress pattern of the part. The ultrasonic approach has the potential of eliminating many of the limitations of existing bond testing technlques. The system is based on the use of high power ultrasonic waves to stress the bond interface with an acoustic pressure sufflcient to break bonds of below minimum allowable strengths. Acceptable production parts may be 100% inspected with no detrimental effects. The technique, equipment, and transducers developed for this test as well as tests which indicate the feasibility of the method are described. Suggestions for further …

From nuclear science symposium; San Francisco, California, USA (14 Nov 1973). The controversy in recent years over the extent of the risk to the public from environmental radioactivity attributable to nuclear facilities (in particular nuclear power plants and fuel reprocessing facilities) has resulted in a lowering of previously acceptable environmental radiation levels. The proposal by the AEC to limit effluents from light-water-cooled nuclear reactors so that the exposure of any individual in the public would not exceed 5 mR/yr, and the pronouncement by the BEIR Committee that the current environmental radiation protection guides are unnecessarily high, are illustrative. In turn the AEC has issued a Safety Guide calling for considerable refinement in the measuring and reporting of effluents from nuclear power plants, and has only recently issued a counterpart dealing with the measuring and reporting of radioactivity in the environs of nuclear power plants. The EPA has also recently issued a guide for the surveillance of environmental radioactivity. Currently, power reactor operators are being required by the AEC Regulatory Staff to conduct detailed, sensitive environmental surveillance. Much of this appears to be based on extremely conservative assumptions throughout, including doseeffect relationships, exposure situations, pathway models, reconcentration factors and intakes, which …

The U. S. Atomic Energy Commission conducted an airborne radioactivity survey of the Red River region of Texas and Oklahoma beginning in December 1955 and ending in May 1956. All or parts of Archer, Clay, and Montague Counties in northern Texas and Carter, Cotton, Jefferson, and Stephens Counties in southern Oklahoma were surveyed. Particular attention was paid to those areas where exposures are found of red beds of the Permian Wichita Group. Field examinations were conducted of anomalies discovered by airborne reconnaissance as well as those reported by private individuals. Forty localities were examined, the majority in sandstones, siltstones, or conglomerates. Uranium and copper minerals were identified at several localities. Ferruginous staining, bleaching of the sandstone color, calcium carbonate cement, and carbonized plant remains are common to the deposits

Preliminary studies indicate that the Imperial Valley has a large geothermal potential. In order to delineate additional geothermal systems a chemical and isotopic investigation of samples from water wells, springs, and geothermal wells in the Imperial Valley and Yuma areas was conducted. Na, K, and Ca concentrations of nearly 200 well water, spring water, hot spring, and geothermal fluid samples from the Imperial Valley area were measured by atomic absorption spectrophotometry. Fournier and Truesdell's function was determined for each water sample. Suspected geothermal areas are identified. Hydrogen and oxygen isotope abundances were determined in order to determine and to identify the source of the water in the Mesa geothermal system. (JGB)

The major source of fresh water at Southport, North Carolina, is a confined multiple-aquifer groundwater system that can be affected in several ways by the proposed unlined cooling-water canal for the Brunswick nuclear power plant. The canal will route brackish water three miles from the Cape Fear Estuary to the plant condensers. The heated brackish effluent will then be routed six miles from discharge to the Ataantic Ocean. To evaluate the impact of the canal on the groundwater system, a mathematical model was used to describe steady-state responses resulting from a variety of conceivable hydrologic stresses. Numerical solutions were obtained by means of finite-difference approximations and a successive line overrelaxation solution technique. The model apprdximated three- dimensional saturated flow in aquifers of variable thickness by assuming two- dimensional flow in each aquifer with interaquifer transfer throughout the groundwater system. Simulation results indicated that saatwater from the estuary will eventually intrude upon Southport's municipal wells regardless of the presence of the proposed Brunswick canal. The canal system will not significantly decrease the time required for estuarine saltwater contamination of the wells. A major portion of the brackish water that downwells from the discharge canal appears to upwell in a parallel drainage …

"CER Geonuclear has developed, in cooperation with the Atomic Energy Commission, a set of detailed plans utilizing nuclear explosives for an underground engineering experiment called project Rio Blanco. The overall objective is to prove the commercial feasibility of using nuclear explosives to recover commercial quantities of tightly held natural gas in the Piceance Basin."

Abstract: This report contains lists of stations at which the U.S. Geological Survey collects water data either on a continuous basis or at least on a daily basis. The files contain daily values for streamflow, reservoir levels or contents, water temperatures, specific conductance, sediment discharge plus data for several other quality parameters that are measured by means of monitoring equipment or result from analyses of samples collected on a daily basis. The stations are listed according to station number within each State. The report lists the availanle retrieval options, the machine -readable output options, user charges and how to obtain data.
