According to some scientists, we must begin using more nuclear power in order to prevent global warming from accelerating. But that creates a huge nuclear waste problem. But scientists at the University of Sheffield think they might have found a very unique way of handing it that could make nuclear waste a problem of the past.
Nuclear Fuel Processes
"Nuclear power plants do not burn any fuel. Instead, they use uranium fuel, consisting of solid ceramic pellets, to produce electricity through a process called fission."
What is Uranium? How Does it Work?
"On a scale arranged according to the increasing mass of their nuclei, uranium is one of the heaviest of all the naturally-occurring elements (Hydrogen is the lightest). Uranium is 18.7 times as dense as water."
Managing Radioactive Materials & Waste
"Any activity that produces or uses radioactive materials generates radioactive waste. Mining, nuclear power generation, and various processes in industry, defense, medicine, and scientific research produce by products that include radioactive waste. Radioactive waste can be in gas, liquid or solid form, and its level of radioactivity can vary. "
Radioactive Waste Management
"All parts of the nuclear fuel cycle produce some radioactive waste (radwaste) and the relatively modest cost of managing and disposing of this is part of the electricity cost, i.e. it is internalised and paid for by the electricity consumers."
How does nuclear waste disposal work?
"Nuclear waste epitomizes the double-edged sword of modern technology. It's a toxic and radioactive byproduct of nuclear medicine, nuclear weapons manufacturing and nuclear power plants. In short, it's the type of waste that reflects one of humankind's greatest leaps in technology, but it also demonstrates our inability to deal with our own advances."
A New Approach to Military Nuclear Waste
"The United States has many pressing nuclear waste problems, but the worst may be the leftovers from the manufacturing of nuclear weapons."
This company cleans up nuclear waste by turning it into glass
"Among all of the terrible ways to get rid of nuclear waste, there's one that stands above the rest for being a little less horrible: turning the radioactive parts into glass, a process called 'vitrification.'"
Glass Offers Improved Means of Storing Nuclear Waste, Researchers Say
"University of Sheffield researchers have shown, for the first time, that a method of storing nuclear waste normally used only for High Level Waste (HLW), could provide a safer, more efficient, and potentially cheaper, solution for the storage and ultimate disposal of Intermediate Level Waste (ILW)."
Nuclear Power Needed To Slow Climate Change, Experts Say
"Some of the world's top climate scientists say wind and solar energy won't be enough to head off extreme global warming, and they're asking environmentalists to support the development of safer nuclear power as one way to cut fossil fuel pollution."
A Message from Dr. Kerry Emanuel
"As climate and energy scientists concerned with global climate change, we are writing to urge you to advocate the development and deployment of safer nuclear energy systems."
