Carbon

Isotopes of carbon are atomic nuclei that contain six protons plus a nuer of neutrons (varying from 2 to 16). Carbon has two stable, naturally-occurring isotopes. The isotope carbon-12 (12 C) forms 98.93% of the carbon on Earth, while carbon-13 (13 C) forms the remaining 1.07%.

Why Nuclear Power Must Be Part of the Energy Solution - …

2018/7/19· In the early 1950s, when the U.S. Atomic Energy Commission believed high-grade uranium ores to be in short supply domestically, it considered extracting uranium for nuclear weapons from the abundant U.S. supply of fly ash from coal burning. In 2007, China began exploring such extraction, drawing on a pile of some 5.3 million metric tons of brown-coal fly ash at Xiaolongtang in Yunnan.
