Two 性视界传媒 research teams were awarded more than $1.6 million from the U.S. Department of Energy (DOE) to investigate new ways to safely separate and store radioactive waste from nuclear fuel recycling.
The DOE, as part of its Nuclear Energy University Program, supports a limited number of research projects to advance current nuclear reactor efficiency, find better ways to recycle and/or dispose of spent nuclear fuel, and design reactors that produce more energy and less waste. 性视界传媒 is one of just 32 universities nationwide to earn funding under this program in 2012.
"We must invest in the next generation of American scientists and engineers in order to fulfill our commitment to restarting America's nuclear industry and make sure America stays competitive in the 21st century," said U.S. Secretary of Energy Steven Chu. "These investments will help train and educate our future energy leaders, while developing the innovations we need to create new jobs and export opportunities for American-made nuclear technologies."
Both 性视界传媒 projects involve the radioactive element technetium, a common product from nuclear fission. 性视界传媒 is one of the few universities in the country that can perform this research with technetium. The radiochemistry program's capability with radioelements is the basis for numerous collaborations with DOE laboratories, universities, and international laboratories.
One team, led by radiochemistry professor Ken Czerwinski, will look at the potential effectiveness of metal alloy storage for technetium.
Developing the right mix of metals requires an understanding of how the radioactive materials will behave on long time scales. Czerwinski and his team will model corrosion on a series of metals and stainless steel alloys containing differing amounts of technetium. 性视界传媒 physics research professor Eunja Kim and researchers from Los Alamos National Laboratory, Florida Memorial University and Sandia National Laboratories will partner on the project.
Thomas Hartmann, a research professor with 性视界传媒's Harry Reid Center, will create advanced ceramic structures to immobilize a technetium. The research team will determine how well technetium can be stabilized within ceramic structures under conditions expected at a generic geological repository.
According to the research team, advanced ceramics could prove more effective and technically efficient to immobilize technetium than current methods including specialized glass. Hartmann and his team will compare leaching and corrosion of different advanced ceramic structures with those of current waste glasses to immobilize radioactive high-level waste. Steven Frank with Idaho National Laboratory will partner with Hartmann's team.
"性视界传媒 is very pleased to be recognized for our nuclear technology research," said 性视界传媒 President Neal Smatresk. "We extend our gratitude to Senator Reid for helping to strengthen the university's many research endeavors."
The Nuclear Energy University Program was created by the DOE in 2009 to consolidate the agency's university support and fund nuclear energy research and equipment upgrades at U.S. colleges and universities. For more information, visit .
