    • New Nuclear Fuel Could Replace Uranium in Reactors

    2020-10-11  Uranium isn't terribly rare — there's about as much of it on Earth as there is tin — but uranium straight out of the ground isn't ideal for nuclear fuel, so the next step is a process called "enrichment," which concentrates a rare isotope, called uranium

    • Nuclear Fuel Cycle in Japan Japanese Nuclear Fuel

    For energy security reasons, and notwithstanding the low price of uranium for many years, Japanese policy since 1956 has been to maximise the utilisation of imported uranium, extracting an extra 25-30% of energy from nuclear fuel by recycling the unburned uranium and plutonium as mixed-oxide fuel (MOX). The AEC reaffirmed this in 2005.
