Index / Uranium (Nuclear Minerals) / Related Environmental Issues

Dr. Conca concludes that the public may not be the best judge of risk. If you ask someone what they are afraid of, they will say things like radiation, fluoridated water, or vaccinations, things that are generally not dangerous. We are only just beginning to realize that texting while driving is really a big problem, or that overuse of opioid medications are leading to a national epidemic of heroine deaths. And these two only because of a flood of advertisements and documentaries on the subjects.

This is an important issue. Without understanding what real risks are, well-intentioned... More →

Index / Uranium (Nuclear Minerals) / Related Environmental Issues

Dr. Conca realizes that many journals and on-line publications need sensational headlines to attract readers. It seems necessary in these times of social media and 24-hour news cycles. But it becomes unethical to push bad science without doing at least a little due diligence. I understand anti-nuke ideology cares little about science and is never held to any technical standard, but in some cases reporting bad science hurts people who need good science to make personal decisions for themselves and their families.

A recent textbook case of this malfeasance is the Fukushima-induced thy... More →

Dr. Conca reports that the McClatchy newspaper chain published a sensational report in late 2015 that suggested over 30,000 nuclear workers at weapons facilities across the United States died from radiation-induced cancer when, in fact, it is impossible to show that even a dozen died.

Over 50,000 workers who worked at U.S. weapons sites over a period of about 40 years have received monetary compensation if they got cancer, regardless of whether the cancer was caused by radiation or not. However, authors Hotakainen, Wise, Matt and Ehlinger of this report decided that if someone recei... More →

Dr. Conca opines that it is highly unlikely that the issues surrounding energy will make any difference in who we choose for our next President. Other concerns, and a few character traits, drown out energy as an important issue in this election. That said, there are distinct differences among the four presidential nominees with regard to energy.

Democratic Party Presidential Nominee Hillary Clinton supports an all-of-the-above energy strategy with a tilt towards non-fossil fuels, including nuclear, to address climate change. Some particulars can be summarized as:

Dom Galeon reports that MIT researchers using the Alcator C-Mod reactor have achieved a new nuclear fusion pressure record of more than 2 atmospheres of pressure. The Alcator C-Mod is set to retire after over 23 years of use but its nuclear fusion experiments have brought us closer to nearly unlimited clean energy.

Nuclear fission reactors have been within our grasp for 50 years now, but harnessing the power of the Sun through stable nuclear fusion has eluded us. Stable nuclear fusion involves a plasma particle density, its confinement time, and its temperature, reaching a particula... More →

Index / Uranium (Nuclear Minerals) / Related Environmental Issues

UEC reports that one of the best kept secrets in Texas is that uranium has been continually mined since the late 1950s. Uranium mining was initially conducted by open-pit mining followed by conventional milling to produce yellowcake, which is harnessed to produce electrical energy in nuclear power plants. In the early 1970s, a new environmentally sensitive means of extraction was developed in South Texas addressing concerns about the disturbance of the surface of the land, dewatering portions of the aquifer to enable men and equipment to work beneath the surface, and later forming vast areas o...

Index / Hydroelectric Power (Dams and Pumped Storage)

Dr. Conca reports that recently (mid-2016), a federal judge forced discussion of a radical step to save endangered salmon: taking out four somewhat large hydroelectric dams on the Lower Snake River in Washington State. These four dams include Ice Harbor, Lower Monumental, Little Goose and Lower Granite Dams. They are fairly old dams and were not optimized for salmon survival. They were built primarily for navigation of barge and various river traffic, for low-carbon power, and to lesser degrees for flood control and irrigation.

Larry Bell appropriately opined in 2011 that much media coverage of the nuclear component of Japan earthquakes and tsunamis tragedy has lacked objectivity and proportionality, compounding already high public anxiety and confusion levels. Excessive attention has been directed to hypothetical radiation dangers relative to the enormous scale of broader havoc wrought by those incredible once-in-three-century natural disasters. Realistic risks have often been exaggerated by poorly informed reporters, along with alarmist agenda-driven commentators presented as experts.

Dr. Conca reports that the MOX Fuel Fabrication Facility (MFFF) in South Carolina is under fire again, with the Administration trying to cut its funding and kill the project, and Russia saying that to do so would abrogate a key nuclear weapons treaty.

Mixed Oxide Fuel (MOX) is a blend of uranium and plutonium (U and Pu) into new commercial nuclear fuel that can be burned in nuclear power reactors but cannot be used to make nuclear weapons.

Dr. Conca reports that the costs of energy are usually discussed in terms of dollars required to construct, fuel and operate power plants or arrays, or the cost of transmitting that energy to whomever is using it. But there are some additional costs that are rarely discussed because we do not know how to determine them, and we do not know who to charge for them. Known as externalities, these vague eventually-someone-has-to-pay kind of costs are hard to put a value on because they are mainly associated human health and environmental effects.

Kirk Sorensen reports that the short answer to the title question is that uranium-fueled reactors can be built right away, but they use fuel inefficiently. Thorium-fueled reactors, on the other hand, are fuel-efficient, almost perfectly so, but that comes at the end of a three-phase process, with the first phase shared by thorium and uranium fuel.

Uranium is the only element with a naturally occurring fissile isotope, meaning the isotope nucleus splits into two smaller nuclei when struck by a neutron traveling at any speed. Few isotopes are fissile. But all thorium and nearly all ur... More →

Licensing small modular reactors (SMRs) presents a new opportunity for standardization in the nuclear power industry, Vanessa Jakovich, counsel at Freshfields Bruckhaus Deringer, told delegates at the World Nuclear Association 41st Annual Symposium in London. Jakovich, who chairs the WNA Licensing and Permitting Task Force, said traditional licensing frameworks and standards pose challenges in terms of standardization and cooperation. But, noting that 19 of the current reactor designs being considered by regulators are SMRs, she said, this seems to be the new world.

The World Nuclear Organization just updated its statements on the world supply of uranium. Current usage is about 66,000 tU per yr. Thus the world present measured resources of uranium (5.9 Mt) in the cost category around 1.5 times present spot prices and used only in conventional reactors, are enough to last for about 90 years. This represents a higher level of assured resources than is normal for most minerals.

Further exploration and higher prices will certainly, on the basis of present geological knowledge, yield further resources as present ones are used up. An initial uranium... More →

Kristen Moran reports that uranium in the U.S. is used primarily for nuclear power, of course. However, uranium mining originally had its roots in the production of uranium-bearing ore in 1898. At that time, sandstone material on the Colorado Plateau in Colorado and Utah was mined primarily for its vanadium content.

Then, in the 1950s, the U.S. permitted a great deal of uranium mining promoted by federal subsidies and rising global demand largely driven by nuclear weapons procurement programs. The trend lasted until the early 1980s, when changing geopolitical circumstances created b... More →
