Nuclear reprocessing is the chemical separation of fission products and unused uranium from spent nuclear fuel. Originally reprocessing was used solely to extract plutonium for producing nuclear weapons. With commercialization of nuclear power the reprocessed plutonium was recycled back into MOX nuclear fuel for thermal reactors.

Fire Resistance . When tested according to the procedures of ASTM E-119 structural lightweight concrete slabs walls and beams have demonstrated greater fire endurance periods than equal equivalent-thickness members made from ordinary aggregate.

Pyroprocessing (from Greek Πυρος = fire) is a process in which materials are subjected to high temperatures (typically over 800 °C) in order to bring about a chemical or physical change.Pyroprocessing includes such terms as ore-roasting calcination and sintering.Equipment for pyroprocessing includes kilns electric arc furnaces and reverberatory furnaces.

The following shows fireresistance periods for typic- al aggregate blends used in

Botanicare s Hortitrellis is a versatile plant support trellis made of durable plastic that can be used over and over for horizontal or vertical applications. Hortitrellis is made from pliable plastic that is great for multiple uses and unlike string net trellis it will not tangle. Use it for scrogging weaving plant branches together in a sea of green or use it vertically with support

x 50M fractions were expanded in discrete particle form and the minus 50M slag was pelletized along with an expansible clay binder before pyroprocessing. The minus 50M slag was pelletized using slag clay ratios of 80 20 and 5050. A batch of clay pellets was also made to serve as a control sample.

In the second part of the kiln the clay mix is expanded and burned at 1 150 °C. The expanded clay is cooled and stored until it is crushed and sorted into saleable fractions. Expanded clay is delivered in bulk. Leca A/S uses various resources as fuels. Fuel is waste solvents from medical industry waste coal from

Pyroprocessing technology has been actively developed at Korea Atomic Energy Research Institute (KAERI) to meet the necessity of addressing spent fuel management issue. This technology has advantages over aqueous process such as less proliferation risk treatment of spent fuel with relatively high heat and radioactivity and compact equipments.

From 1 M³ Clay to 5 M³ Expanded Clay. Expanded clay is produced from naturally and abundantly available clay. The clay is extracted pre-treated and introduced to rotary kilns. These kilns are heated to temperatures up to 1.150 ºC and this process transforms the clay into various sized lightweight aggregates with a hard ceramic shell and a
