A P-2 centrifuge roughly uses an area of 0.8 m, consumes approximately 30 W, and has a capacity of 5 SWU/yr. Assuming that you are a terrorist and your garage (or your parent's garage) is filled to capacity with these centrifuges, 1) how long will it take to acquire 28 kg of uranium at an enrichment of 90% 235U, 2) how much uranium feed material would you use, and 3) how much energy (W-hr) would you consume? Assume your feed is natural uranium and that the feed, product, and waste uranium does not consume any floor space in your garage. Make sure to specifically state what you assumed for the enrichment of your waste uranium is.
