Letter to the editor: Saving our toxic nuclear legacy, leave uranium in the ground and offer energy options
To the editor:
When creating any system, whether a building, a community or an energy system, waste products need to be safely managed. This should be true if we’re building an energy system where the waste products can cause cancer and genetic mutations in humans or any organism within range of long-lived radioactive particles. However, it’s hasn’t been.
First discovered in 1895, radiation was shown to kill bacteria in 1898; however, with a high energy potential and money-making promise, radioactivity was not linked to cancer and genetic change until much later and even then its true health effects were hidden from miners and the public. Because the geologic Chinle Formation on the Navajo Nation is rich in Uranium, Navajo men were put to work without protection from known hazards. Several hundred Navajos became sick from radiation exposure, many at the same time that other Navajos enlisted in the Marines to become Navajo Code Talkers. Health effects from mining Uranium persist on the Navajo Nation with numerous pit mines still open and potentially affecting water, plants, livestock and Navajo. The amount of pain, illness, death and cost are still unknown. (See Judy Pasternak, 2011, Yellow Dirt.)
With the geologic uplift of the Grand Canyon upwarp, it’s hypothesized that numerous vertical shafts eroded allowing broken rock carrying Uranium from the Chinle Formation to fall into these “breccia pipes”. Left alone, the Uranium and other metals remain isolated from the biotic world; drilled into, these metals can migrate into interconnected aquifers that discharge into the Colorado River, water often used to grow food. The Grand Canyon upwarp has the greatest concentration of Uranium containing breccia pipes in the world.
The Canyon Mine lies six miles south of the Canyon’s rim and administrators have consistently insisted they would protect the aquifer water (used by native people and local communities). When the mine re-opened in 2017, the breccia pipe mine shaft was filled with 200 swimming pools of water that was pumped out and sprayed on the regional landscape without concern for other living organisms. This region is sacred to the Hopi, Navajo, Pai and other native people. The Canyon Mine has promised to create jobs; however, tourism and outdoor activities “support over 9,000 jobs, contribute over $938 million annually to [local] economies, and generate over $160 million in annual state and local tax revenues. Uranium mining threatens these economic drivers while possessing little capacity to support the regional economy.” www.grandcanyontrust.org
Under President Obama, a twenty-year moratorium on Uranium mining was instituted to allow for compilation and review of scientific information and energy policy. President Trump has requested and will receive a proposal from the nuclear industry to assess opening up mining on the Grand Canyon upwarp. Mined Uranium would be used to generate nuclear electricity in reactors that are at or nearing their engineered lifespan. Building new nuclear reactors is massively expensive and concrete, the primary component of reactors, is the second largest emitter of climate changing CO2. (United Nations, IPCC report). Claims that nuclear energy is climate neutral only look at the internal nuclear reaction and ignore the entire fuel cycle necessary to keep the nuclear system functioning. Currently, nuclear waste is stored on-site at numerous reactors, several of which have moderate security and leaky infrastructure. The one national nuclear repository, Yucca Mountain, has been mothballed after expending $15Billion of taxpayer money.
To be sure, mining engineers are very intelligent people, and if they can pull Uranium out of breccia pipes, they can pull Uranium out of 1940’s open mining pits and then close off any radiation leakage. These same engineers could pull nuclear fuels from corroding storage bins on-site at nuclear reactors across the country. If a future President decides we need fewer nuclear weapons, future engineers could pull those radioactive elements, though it is questionable whether nuclear power will even be necessary given energy conservation and emerging sustainable energy sources.
In short, our country is not at lack of energy, but our current leadership is at lack of offering practical energy options. The best option is to leave the rranium in the ground and clean up our country’s toxic nuclear legacy.
