Sphagnum latter being the slowly decaying matter underneath. Dried sphagnum moss is also used in northern Arctic regions as an insulating material. Anaerobic acidic sphagnum bogs have low rates of decay, and hence preserve plant fragments and pollen to allow reconstruction of past environments. They even preserve human bodies for millennia; examples of these preserved specimens are Tollund Man, Haraldskær Woman, Clonycavan Man and Lindow Man. Such bogs can also preserve human hair and clothing, one of the most noteworthy examples being Egtved Girl, Denmark. Because of the acidity of peat, however, bones are dissolved rather than preserved. These bogs have
Resende Nuclear Fuel Factory Resende Nuclear Fuel Factory The Nuclear Fuel Factory (FCN) is located near Resende, state of Rio de Janeiro, comprising three units, and has a production capacity of 280 tons of uranium per year. At present, FCN was modernized and produces at the Components and Assembly Unit the fuel rods and fuel elements needed for Brazilian nuclear reactors. The Reconversion and Pellets Production Unit is operating since 1999 with a capacity of 160 tons of UO2 pellets/year. The UO2 reconversion line uses the AUC process. The Nuclear Fuel Factory also produces other fuel element components, such as top and bottom nozzles,
