In the aftermath of Yucca's mothballing, the DOE has pursued a diverse strategy of nuclear waste management that includes tentative plans for consolidated interim storage facilities, tests of deep boreholes as another possible long - term storage technique, and the development of «consent - based» siting protocols to gain support from municipal and state governments.

Scientists at The Geological Society of America (GSA) meeting in Denver will describe the potential of shale formations; challenges of deep borehole disposal; and their progress in building a computer model to help improve understanding of the geologic processes that are important for safe disposal of high - level waste.

«If we want to put waste where we'll never see it again,» he added, it should go at the bottom of a deep borehole.

Together with the Disaster and Emergency Management Presidency of Turkey AFAD, several 300 meter deep holes are currently being drilled around the eastern Marmara Sea, into which highly sensitive borehole seismometers will be placed.

Borehole advocates say tubes of cesium and strontium waste stored in a pool at the Hanford site in Washington could go deep underground.

Meanwhile, the Department of Energy (DOE) in recent years has directed money to so - called «deep boreholes» as a less - objectionable and cheaper way to deal with some of the waste.

For example, an entire nuclear cycle involving light - water reactors, reprocessing of the spent fuel, and disposal of small «packages» of highly radioactive nuclear waste in deep boreholes could prove an attractive option, Moniz noted.

But the farthest we have ventured inside our own planet — the 7.6 - mile - deep Kola Superdeep Borehole in the Russian Arctic — got us only 0.4 percent of the way to the core.

Though the concept of borehole disposal, which would see radioactive waste entombed far deeper than traditional repositories, has existed for decades, the idea has been revived in recent years, spurred by troubles in finding a long - term home for the country's spent fuel.

You will find Güralp instruments gathering seismic data in the harshest of environments, from the Antarctic ice sheet; to boreholes 100s of metres deep; to the world's most active volcanoes and deepest ocean trenches.

As far as this historic period is concerned, the reconstruction of past temperatures based on deep boreholes in deep permafrost is one of the best past temperature proxies we have (for the global regions with permafrost — polar regions and mountainous regions)-- as a signal of average temperatures it's even more accurate than historic direct measurements of the air temperature, since the earth's upper crust acts as a near perfect conservator of past temperatures — given that no water circulation takes place, which is precisely the case in permafrost where by definition the water is frozen.

The solutions they considered were: setting up a rural water supply program providing poor communities in Africa with deep boreholes and public hand pumps; developing campaigns that raise awareness of disease transmission, health costs, and the social benefits of sanitation; ensuring affected communities have access to technology to remove contaminants in raw water supplies; building reservoirs in some parts of Africa, such as the sparsely inhabited Blue Nile gorge in Ethiopia.

The building has a closed loop geoexchange system with 280 boreholes 400 feet deep; this cools or heats water which is piped through the thermal mass of the concrete floors, heating or cooling the space.

«They had done far more extensive and sophisticated analysis of the weather records, confirmed by «proxy» data such as studies of tree rings and measurements of old temperatures that lingered in deep boreholes.»

Tree rings, coral skeletons, and glacial ice cores (Figure 3) are proxies for annual temperature records, while boreholes (holes drilled deep into Earth's crust) can show temperature shifts over longer periods of time.

But fracking, which involves the high - pressure injection of water or a fluid mixture into a borehole to create cracks in deep - rock formations through which gas or petroleum can flow, is inherently dangerous.
