Researchers at UNLV are addressing the nuclear waste predicament by transforming potential hazards into usable energy
UNLV's Innovative Approach to Uranium Hexafluoride Conversion
The University of Nevada, Las Vegas (UNLV) is making strides in the field of nuclear energy with its research on uranium hexafluoride (UF6). This potentially deadly substance, which can cause searing burns and acidic fluid in the lungs, is stored in canisters around the world and has been a concern due to its volatility and risk of degradation[1][2].
UNLV's radiochemistry program, under the leadership of professor David Hatchett, has developed techniques to handle and convert UF6, making it safer to handle[2]. The process involves converting UF6 into a more stable uranium product, which is less hazardous and more environmentally friendly[1].
This conversion is crucial because UF6 is highly toxic and risky if not handled properly[1][2]. By making UF6 safer, UNLV's techniques can help mitigate the risks associated with storage and disposal of this hazardous material[1][2].
The reclaimed uranium from this process can be used in several strategic applications. For instance, the stable uranium product can be used to sustain fission reactions in nuclear reactors, which are essential for generating electricity[4]. By recovering and reusing uranium, UNLV's techniques support the nuclear fuel cycle, enhancing the efficiency and sustainability of nuclear energy production.
Moreover, the process reduces the environmental impact of nuclear waste by converting hazardous materials into safer forms[1][2]. This is particularly important given the global concern over the management of radioactive waste. There are 1.2 million metric tons of radioactive waste globally, with about 700,000 metric tons (1.5 billion pounds) in the U.S.[3]
UNLV collaborates with private contractors like Urenco to access UF6 for research, ensuring that the techniques developed are practical and scalable[2]. This collaboration also supports educational and research goals, preparing students for roles in national labs and advancing the field of radiochemistry[2].
The goal of UNLV's work is to make the uranium hexafluoride compound safe, and then reuse it without producing additional waste[1]. This approach, referred to as "strategic material recovery" by Hatchett, has shown promise for scaling up, but more research and work are needed before it can be used on an industrial level[1].
Hatchett suggests that using uranium fuel is attractive for augmenting solar or hydroelectric energy, such as the Hoover Dam that relies on dwindling Colorado River water[5]. By recovering and reusing uranium, UNLV's techniques can help ensure the long-term sustainability of these energy sources.
