Revisit Example 8-2. (a) If the cost of raw uranium is $66/kg, what percent of the cost of $40 million worth of fuel rods does this amount constitute?

(b) If the cost increases to $230/kg, and all other cost components of the refueling remain the same, what is the new cost of the refueling each year?

Information from Example 8-2: A nuclear power plant with its capital cost fully repaid. There is 155,000 kg of uranium (175,800 kg of UO2) in the reactor core. U-235 concentration is 2.8% and each year, one-third of the reactor fuel should be replaced at the cost of $40 million, which has built into $0.001 /KWh to be paid to fund for the management of nuclear waste. Non-fuel operation and maintenance cost of this power plant amounts to $118 million/year.
