uranium thorium rate

Background As time passes after such material has formed uranium234 in the sample with a halflife of 245000 years decays to thorium230 citation needed Thorium230 is itself radioactive with a halflife of 75000 years so instead of accumulating indefinitely as  uae dealers of rock crushers in malaysia for sale

    Thorium is an element that is more than 3 times more abundant worldwide and is an alternate source of nuclear power This element itself is not fissile but when used in a Liquid Fluoride Thorium Reactor LFTR it can potentially be a source of nuclear power that is cheaper cleaner and safer compared to current uranium power plants

    A gram of uranium238 decays at a rate of 12 kBq producing thorium234 at a rate of 12 kBq which decays into protactinium234 which decays into uranium234 and so on Each nuclide in the decay chain accumulates to an equilibrium concentration such that it is produced at and decays away at the same rate as the ultimate ancestor nuclide uranium238

    The report raises the question how much thorium is recoverable at a price of 500kg in 1969 dollars perhaps 3000kg today The answer is 3 billion short tonnes or 2700000000 metric tonnes enough to last us 40000 years in our extreme scenario For uranium the figures will be not much different And no 3000kg is not a ridiculous price
