As it is normal to allow used nuclear fuel to stand for about five years before reprocessing, much of this activity will decay away leaving 4.7 MBq of 102 Rh and 5.0 MBq of 102m Rh. If the rhodium metal was then left for 20 years after fission, the 13.3 grams of rhodium metal would contain 1.3 kBq of 102 Rh and 500 kBq of 102m Rh.
The Hanford Site occupies 586 square miles (1,518 km 2) – roughly equivalent to half the total area of Rhode Island – within Benton County, Washington. [1] [2] It is a desert environment receiving less than ten inches (250 mm) of annual precipitation, covered mostly by shrub-steppe vegetation.
Gold-198 (198 Au) is a radioactive isotope of gold. It undergoes beta decay to stable 198 Hg with a half-life of 2.69464 days. The decay properties of 198 Au have led to widespread interest in its potential use in radiotherapy for cancer treatments. This isotope has also found use in nuclear weapons research and as a radioactive tracer in ...
A nuclear waste repository near Carlsbad could be used to generate "clean energy" as federal official sought input from the public for the project.. It’s part of the U.S. Department of Energy ...
TRU nuclear waste in need of disposal could increase at Los Alamos as it was planned to generate 30 pits a year, combined with 50 a year by 2030 at the DOE’s Savannah River Site in South Carolina.
The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
Sm in nuclear waste would require separation from other isotopes of samarium. Given the smaller quantities and its low-energy radioactivity, 151 Sm is less dangerous than 90 Sr and 137 Cs and can also be left to decay for ~970 years. Finally, there are seven long-lived fission products. They have much longer half-lives in the range 211,000 ...
Scientists at the Waste Isolation Pilot Plant began using aerial drones to scope out areas of the underground nuclear waste repository to ensure they are safe before sending workers in.
