Isotopes of thorium Wikipedia

Thorium 90 Th has seven naturally occurring isotopes but none are stable One isotope 232 Th is relatively stable with a half life of 1 405×10 10 years considerably longer than the age of the Earth and even slightly longer than the generally accepted age of the universe This isotope makes up nearly all natural thorium so thorium was considered to be mononuclidic

Thorium the fuel of the future – Central Times

The European Council for Nuclear Research estimates that 1 tonne of thorium generates as much energy as 200 tonnes of uranium which is also equivalent to 3 500 000 tonnes of coal Finally the sole reason that most of the world never invested in thorium is due to the fact that it cannot be made into nuclear weapons which I believe is a

Thorium Energy Education

Thorium is the 90 th element on the periodic table the second heaviest element on Earth Thorium is known for its potential to provide nuclear energy in nuclear reactors much like uranium which is the current dominant nuclear fuel It was discovered in 1828 by Swedish chemist Jons Jakob Berzelius who named it after Thor the Norse god of thunder Only one isotope of thorium is found in nature

Thorium As Nuclear Fuel the good and the bad

Reactors that use thorium are operating on what s called the Thorium Uranium Th U fuel cycle The vast majority of existing or proposed nuclear reactors however use enriched uranium U 235 or reprocessed plutonium Pu 239 as fuel in the Uranium Plutonium cycle and only a handful have used thorium

Thorium fuel cycle Wikipedia

The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium 232 Th as the fertile material In the reactor 232 Th is transmuted into the fissile artificial uranium isotope 233 U which is the nuclear fuel Unlike natural uranium natural thorium contains only trace amounts of fissile material such as 231 Th which are insufficient to initiate a nuclear chain reaction

thorium Description Properties Uses Britannica
