Nuclear Energy Wastes

What ways can we reduce the wastes produced in the reactor core. How can uranium be separated from Plutonium?

AIM: Storage of Nuclear Wastes To Reduce wastes of radioactive contamination. To create and design a suitable waste Storage. Potential Problem Cost of construction Storage facilities

Nuclear Wastes are produced in many different ways: Wastes created as a result of radioactive contamination Wastes produced as a by product of uranium enrichment. Radioactive Isotopes with long half lives tend to be alpha and beta emitters.

Dry Cask Storage Dry cask storage is a method of storing high-level radioactive, such as spent nuclear fuel that has already been cooled in the spent fuel pool for at least one year. When inside, the fuel rods are surrounded by gases.. Each cylinder is surrounded by additional steel, concrete, to provide radiation shielding to workers and members of the public. Some of the cask designs can be used for both storage and transportation. Companies Holtec Intl, NAC Intl. and Areva. Cost 25 million dollars for two hundred Cylinders

Materials Needed: A container, stabilizer, casing, a concrete wall, water storage tanker, a coolant, noble gases, Geological Location, a rotational walker and few human labors. The outer structure diagram will have a container, stabilizer, casing and additional concrete, while the inner basement structure will have a concrete wall, water storage tanker, a coolant, noble gases, rotational walker e.t.c. The container will contain the noble gases. The stabilizer: fillers material to improve physical and chemical stability of the waste. Casing: special material highly resistant to corrosion.
