the periodic table Z > 92 (U) The transuranium elements (also known as transuranic elements) are the chemical elements with atomic numbers greater than...

Transuranic waste (TRU) is stated by U.S. regulations, and independent of state or origin, to be waste which has been contaminated with alpha emitting...

those designed to use primarily uranium and transuranics from those designed to use thorium and avoid transuranics. These designs are: Fast breeder reactors...

isotopes such as radium (Ra-226) were used, but in modern times the transuranic isotopes Am-241 and Pu-239 are almost exclusively used in AmBe and PuBe...

reactor with a nuclear fuel cycle that produced no transuranic waste and, in fact, could consume transuranic waste. It proceeded as far as large-scale tests...

explosions. Of the transuranic elements—those with atomic numbers greater than 92—only plutonium and neptunium occur naturally on Earth. Transuranic elements have...

plutonium together with other transuranic elements were generated in the uranium ore body. This plutonium and the other transuranics remained immobile until...

rhombohedral, and tetragonal. For some of the synthetically produced transuranic elements, available samples have been too small to determine crystal...

which is long due primarily to the long half-life of alpha-emitting transuranic actinides. Some nuclear fusion-fission hybrids are proposed to make use...

formed as a plutonium daughter. 244Pu has the longest half-life of all transuranic nuclides and is produced only in the r-process in supernovae and colliding...
