Variation in the price of the energy in function of the rate of return applied at the cost of the uranium

The Brazilian Nuclear Plan (BNP) forecasts the construction of, at least, four nuclear power plant besides Angra-3 till 2030. It also contemplates the possibility of other eight 1000 MWe nuclear power plants being built. Brazil holds the 6th largest uranium reserves in the world. Considering that only about one third of the territory has been prospected to date, fuel supply for those nuclear plants, as far as uranium ore reserves are concerned, is already assured. Fuel cycle technology dominance also guarantees to the country a position in an exclusive group of nations. The BNP outlooks the expansion of the nuclear fuel cycle looking for independence of foreign sources of supply. Estimating the nuclear fuel cost from national fuel cycle cost is still difficult due to lack of real cost data. Based on these facts it is presented a sensibility analysis of the nuclear fuel cost, taking into consideration exchange rate variation and the investment in internal rate of return. (author)
