When radioactive waste is disposed in a salt dome, it is important to evaluate the hydrologic stability of the dome. It depends on the dissolution rate of the dome, which again is determined by the transport and dispersion properties of the cap rock and the other formations surrounding the dome. The same properties are also required in safety assessment work for calculation of migration of radionuclides, which might be released from the dome to the surrounding strata.

Operation And Maintenance

This paper summarizes the results of the technical and economic data of nominal 280 MW Compressed Air Energy Storage Plants (CAES) using caverns in salt domes located in southeastern parts of Mississippi for intermediate duty generation of 1,000 hours per year and peaking duty generation of 750 hours per year. The plants are assumed to operate 90% time on Natural Gas and 10% of the time on No. 2 distillate. A weekly cycle of 10 hours of generation and 12 hours of charging daily with 15 hours of weekend charging was the basis for the study. The study includes conceptual layout, optimization, detailed cost analyses, reliability and operation and maintenance of the Compressed Air Energy storage plant. The objective of the study is low capital cost of the CAES plant and optimum performance.

A salt dome is a familiar example of a three‐dimensional (3-D) geologic structure. Surprisingly, most of the literature devoted to the investigation of salt domes deals only with cross‐sectional views of the domes. This is particularly true for seismic work. A notable exception is the work of French (1974) which discusses inaccuracies in focusing introduced by performing two‐dimensional (2-D) migration of data obtained over a 3-D model structure.

Seismic Reflections

Abstract In the Dnipro-Donets depression, the Devonian salt during Carboniferous time became movable and created salt domes in the Permian, moving to the sea bottom and flowing therewith, forming bodies visible today as salt canopies and overhangs. These features are clear pieces of evidence of salt exposure on the surface, especially considering belts of reservoirs around salt domes. These reservoirs can be extremely prolific in some wells. Previous exploration targeting such deposits was driven mainly by drilling wells within the areas of known deep fields such as Medvedivske, Zakhidno-Khrestyschenske and others in the central part of the DDB. These reservoirs are composed of poorly sorted coarse material of wide variety of rocks including sandstones, carbonates, dolomites, igneous rocks of deep (granites), and shallow (diabases) formations. Currently, with the availability of 3D seismic surveys, these deposits become visible as bright spots and flat spots. Although it is not a 100% indicator due to fact that shallow salt canopies and lithology changes of rocks around salt domes may also interpret seismic reflections. It is good to mention that the Permian is an aridic environment with gradually losing water influx to the basin from base to top within the thickness of more than 1-2 kilometers. It could be utilized as boundary analogues to cover most of the possible intermediate scenarios in three areas. The first analogue is the outcropped salt dome in Solotvyno village in Carpathian mountains in western Ukraine close to the Romania border. This salt dome is an important example of showing the current deposition of transported coarse material from depth around salt domes. The second one is salt domes exposed as mountains of the Oman desert where it is possible to follow the material path approaching the salt uplift. And the third example is the Death Valley in Arizona, USA. The valley is an example of fans mostly deposited by gravity rather than permanent water flows. It good to mention that there are more examples that could be treated as direct analogues (the Zagros mountains in Iran) but they are not easily accessible for field trips if needed. For recognizing real targets vs artifacts, applying the knowledge of current deposition examples around the world would help dramatically (Western Ukraine, Oman, Death Valley in Arizona).

Interactive Map

<p>The political and social debate on nuclear energy in Germany has been characterized for many decades by a high potential for conflict and dissatisfaction. Especially the controversies surrounding the Gorleben salt dome gained international attention and changed the relationship between citizens and political decision-makers from the local to the national level. With the Repository Site Selection Act of 2013 (StandAG, first amendment in 2017) a new approach was chosen to implement a participative, inclusive and transparent search process for the best possible repository for high-level radioactive waste in Germany. In this context, a self-learning process was proclaimed, based on a white (unbiased) map, which should give citizens an active role. However, the first interim report of the Federal Company for Radioactive Waste Disposal and the publication of the colorful map, in which geologically suitable areas were identified on a large scale, already revealed a massive potential for conflict. Many citizens and activists who were already protesting against the Gorleben salt dome criticized in this early phase of the process, the lack of transparency and opportunities to have a say on the possible sitting regions.</p><p>To address this criticism, we want to provide an interactive map as an online platform that presents existing geographic data, that enables people to contribute spatially-located information (geological, on-surface), and thus a possibility for people to interact and participate regarding the possible siting regions. Therefore, we collect existing spatial data that is relevant to the ongoing process, such as possible siting regions (declared by the Federal Company for Radioactive Waste Disposal), nuclear power plants (active/inactive, research facilities, etc.), storage facilities (on-site, central, interim, etc.), historically relevant locations (places of protest, uranium enrichment & processing facilities, etc.) as well as basic data for orientation. We implement two possibilities for participatory interaction: (1) adding spatially-located notes that contain own experiences or local knowledge (e.g. reports, concerns, suggestions) and (2) initiating a platform for a spatially-located discussion. Against the background of transdisciplinary research, in an iterative process, we want to evaluate the participatory value of this application by consulting civic as well as scientific actors. We, therefore, employ focus groups with a transdisciplinary support group of citizens beforehand and surveys after using the application. For this panel we want to present our primary results from a first test with the aforementioned focus groups.</p><p>Aside from testing the suitability of such a mode of participation, we aim to analyze where problems emerge, and which information is necessary and/or might lead to conflict. Finally, we want to gain insight into how such modes of participation influence the quality of dialogue and how it contributes to the overall perception of a procedurally just process.</p>

Shallow Part

A gravity survey of 50 stations over one of the mounds near the edge of the Continental Shelf developed a strong, roughly circular negative anomaly. The gravity minimum is similar in magnitude and lateral extent to those over large salt domes in the on‐shore and explored offshore areas of the Gulf Coast. An approximate quantitative evaluation shows that the minimum can be accounted for quite completely by a large shallow salt dome. The shallow part of the dome is approximately co‐extensive with the topographic feature and it seems quite certain that this particular mound is genetically, related to a salt dome. If other similar mounds also are salt domes, the area of domes off the Louisiana coast is approximately doubled over that presently known from commercial geophysical exploration.

Geometrical Argument

Turning seismic waves, which first travel downward and then upward before (and after) reflection, have been recorded in a 3-D seismic survey conducted over an overhanging salt dome. Careful processing of these turning waves enables the imaging of the underside of the salt dome and of intrusions of salt into vertical faults radiating from the dome. When seismic wave velocity increases with depth, waves that initially travel downward are reflected and may turn so as to travel upward before reflection. A simple geometrical argument suggests that these turning waves are likely to exhibit abnormal moveout in common‐midpoint (CMP) gathers, in that reflection time decreases with increasing source‐receiver offset. This abnormal moveout and the attenuation of turning waves by most migration methods suggest that conventional seismic processing does not properly image turning waves. The most important step in imaging turning waves, assuming that they have been recorded, is the migration process. Simple and inexpensive modifications to the conventional phase‐shift migration method enable turning waves to be imaged for little additional computational cost. The examples provided in this paper suggest that these and other such modifications to conventional processing should be used routinely when imaging salt domes.
