- A 600 MW PWR nuclear plant uses 4% enriched uranium fuel has a thermal efficiency of 36%. The burn up allowed of the fissionable portion of the fuel is 20%. Calculate how many metric tons of natural uranium is placed in the reactor vessel for one-year continuous operation.The hull of a boat has a volume of 150 m3, and the total mass of the boat when empty is 8560 kg. Determine how much load this boat can carry without sinking when (a) in a fresh water lake and (b) in seawater with a specific gravity of 1.09. A university campus has 200 classrooms and 400 faculty offices. The classrooms are equipped with 12 fluorescent tubes, each consuming 110 W, including the electricity used by the ballasts. The faculty offices, on average, have half as many tubes. The campus is open 240 days a year. The classrooms and faculty offices are not occupied an average of 4 h a day, but the lights are kept on. If the unit cost of electricity is $0.11/kWh, determine how much the campus will save a year if the lights in the classrooms and faculty offices are turned off during unoccupied periods. Draw a figure or FBD that will support the problem. Explain each step by step formula.
