Miner Buries Uranium Myths

Posted February 11, 2007 6:48 PM

From The Australian:

GREG Hall makes no bones about it: there is too much hype in the Australian uranium sector and it is leading to artificially high expectations. The managing director of Toro Energy should know. He's a former manager of mine operations and marketing manager for Rio Tinto's ERA operations and a former mine manager for Olympic Dam when it was owned by WMC. Toro Energy is a South Australian uranium explorer that was formed through the amalgamation of the uranium interests of Oxiana and Minotaur Exploration and listed last year after raising $18 million through an IPO. "I believe there is an imbalance between the information the public is hearing from the anti-uranium lobby, and the industry knowledge base," Hall said this week. "The industry needs to be willing to be more outspoken." The current uranium boom is very much stock exchange-driven because, despite the recent lift in uranium prices to a reported $US75 a pound, the fundamentals of the supply side of the industry have not changed much for most of the past decade. While Hall is not a supporter of the claim in the Switkowski report on Australia's nuclear options that there is insufficient nuclear expertise in Australia - he cites more than 30 years' nuclear regulatory experience in South Australia and the Northern Territory and a similar timescale in Western Australia through the ban on thorium extraction - he says it is unrealistic to expect an immediate surge in new uranium mines.

There has been recent mention of utilizing the natural decay of radioisotopes, which is what keeps the earth's core hot. I figure one possibility would be to use a robotic driller to eat a passageway down through the core as part of construction of a geothermal source.

Such a methodology could permit geothermal power generation at way more locations than currently known.

Wouldn't the use of a radioisotope, such as uranium 235, work as well inside a containment vessel and controlled environment, i.e. Nuclear Reactor? Also, why would you want to drill clear to the core of the earth for geothermal, that is a lot of molten mantle material to penetrate just to get to the core. Wouldn't the mantle supply sufficient heat?

Sorry, I was just being lazy. I mean drill down far enough to reach near the hot magma, often within several miles of the surface. That way we can get clean power without the dangers of nuclear fission.

I am not an expert at anything here but I do have a question. Seems to me you would have to pump or draw liquids "water" to the drilled area. Could this cause a cooling effect that might lead to earthquake activity, given the amount of excess water that may be needed to effectivly create enough Power for it to be worthwhile?

( lets say 400 Megawatts)

I recently read an article which mentioned seismic risk. I am not sure if it refers to the fact that most geothermal power production is already in a geologically active area or that the process of building and operating the plant may trigger an earthquake or magma flow. It could be some of both, especially considering that the present way of establishing passageways involves drilling, say, two wells and then fracturing, with hydrostatic pressure, the rock between them to make the pathway through hot rock.
