This would generate at least a hundred times more electricity from used nuclear fuel and decrease the long - term radiotoxicity of the remaining wastes. (gehitachiprism.com)
In a once - through fuel cycle, more than 98 percent of the expected long - term radiotoxicity is caused by the resulting neptunium 237 and plutonium 242 (with half - lives of 2.14 million and 387,000 years, respectively). (scientificamerican.com)
Calculations showed that the effective half - lives of these LLFPs could be drastically reduced so that total radiotoxicity at long cooling time domain will be efficiently reduced. (sciencedaily.com)
