    Expanded Clay Aggregate - Wikivisually

    Lightweight expanded clay aggregate (LECA) or expanded clay (exclay) is a light weight aggregate made by heating clay to around 1,200 °C (2,190 °F) in a rotary kiln. The yielding gases expand the clay by thousands of small bubbles forming during heating producing a honeycomb structure.

    Plutonium And Reprocessing Of Spent Nuclear Fuel Science

    Sep 28, 2001 · H istorically, chemical separation or “reprocessing” technologies have been used to separate the plutonium and uranium in irradiated nuclear fuel from fission products and from other isotopes that have built up as a result of neutron absorption. Reprocessing is as old as nuclear reactors, because the first reactors were built to produce plutonium for nuclear weapons.
