Effects of temperature on the absolute permeability of consolidated sandstone

Description: The effect of temperature on absolute permeability has been a point of disagreement in the petroleum literature for many years. Recent work at Stanford University has shown no dependence on temperature of the absolute permeability to water of unconsolidated sand cores. The objective of this report is to extend the investigation to consolidated sandstone by following similar experimental procedures and observing whether any temperature effects exist. Fontainebleau sandstone was chosen as the cor… more

Final Report: Phase II Geothermal Exploration and Geothermal Power Plant Update for Ascension Island, South Atlantic Ocean

Description: The Phase I study of the geothermal potential of Ascension Island concluded that the possibility of a geothermal resource existing under the island was excellent. This conclusion was based on the presence of young volcanic rocks (a heat source close to the surface), an ample supply of water from the sea, and high permeability of many of the rocks which make up the island. The assumption was made that the resource would be similar to geothermal systems in the Azores or Japan, and a conceptual de… more

Helium cooled Flibe blanket

Description: The blanket design uses a pressure vessel to contain the 50 atmosphere helium gas. Helium cools the first wall and blanket internals. The internals consist of a bed of beryllium balls nominally 1 cm diameter in which neutrons are multiplied and later captured, breeding adequate (even excess) amounts of tritium and releasing energy in exothermic nuclear reactions. Tritium is bred in the molten flibe salt which flows slowly (0.1m/sec) in steel tubes. The salt is kept reducing by periodic reacting… more

Tritium permeation and recovery for the Flibe/He blanket design

Description: This study assumes tritium to be a gas dissolved in molten salt, with TF formation suppressed. Tritium permeates readily through the hot steel tubes of the reactor and steam generator and will leak into the steam system at the rate of about one gram per day in the absence of special permeation barriers, assuming that 1% of the helium coolant flow rate is processed for tritium recovery at 90% efficiency per pass. Tritiated water in the steam system is a personnel hazard at concentration levels w… more

Transient moisture migration in concrete during severe reactor accidents

Description: In the most severe hypothetical core heatup accidents in High Temperature Gas Cooled Reactors, the heatup of the concrete reactor vessel can result in gas release from degrading concrete which can ultimately lead to containment building failure. This gas release is largely affected by the moisture migration during concrete heatup. Moisture migration in concrete is also of interest in Light Water Reactors (LWR) core meltdown accidents. Therefore, the general problem of moisture migration in a he… more

Assessment of problems associated with tritium containment

Description: Preventing tritium leakage across a large heat transfer area at high temperature is one of the most difficult problems associated with a D-T fusion reactor design. One of the most efficient methods to reduce the mobility of tritium is to convert it to tritiated water. Most solid breeder systems use a purge gas and assume tritium will be oxidized into the water form. For 17 Li-83Pb system, a double-walled steam generator is used. Tritium is assumed to be oxidized across the gap in between the tw… more

Rock Matrix and Fracture Analysis of Flow in Western Tight Gas Sands. Quarterly Technical Progress Report, September--December 1984

Description: The presence of natural fractures is often cited as a key factor in gas production for both fractured and unfractured wells. Numerous vertical fractures have been found in cores recovered in the Multi-Well Project. The cores show that by far the majority of fractures become filled with calcite cement. However, calcite-filled fractures are not necessarily a seal to gas flow. As part of this project, flow measurements are being made along and across selected fractured samples as a function of ove… more
