6) Welcome to Mars! After a glowing review by your ME461 Instructor, you are the chief nuclear refueling engineer at the Londres Nova Nuclear Power Station on Mars. This power station

consists of 3 Fissionator-class nuclear power plants, each producing 3000MW. a) What is the minimum amount of U-235 will you need to order from the Ceres Uranium Corporation to keep these reactors running for two years? (Assume complete burnup) b) The Phobos Plutonium Production Plant is interested in selling you Pu fuel. Since Fissionator-class reactors can also run off of Pu-239, calculate how much plutonium it would take to keep them running the same amount of time. (hint: this will require finding a new value in table 3.4 for your equation)/n7) Due to your excellent work on the previous refueling outage (the reactor hasn't melted yet!), the nearby Mariner Valley Nuclear Power Station has requested some assistance. They would like you to calculate the macroscopic neutron absorption cross section of a proposed UO2 fuel loading that they're considering. Assume 7 w/o enriched uranium. Their reactor operates at a fuel temperature of 600 deg C (i.e., Assume non 1/v behavior).
