1. The problem statement, all variables and given/known data I am currently taking an introductory course in nuclear engineering. We are using Lamarsh's Introduction to Nuclear Engineering, 3rd Ed. My question revolves around calculating fuel burnup and consumption rates for thermal reactors and fast reactors. In particular, problem 9 from chapter 4: If a nuclear reactor is assumed to have a recoverable energy per fission of 200 MeV, calculate the fuel burnup and consumption rates in g/MWd for: (a) thermal reactors fueled with 233U or 239Pu; and (b) fast reactors fueled with 239Pu. [Note: In part (b), take the capture-to-fission ratio to be 0.065] 2. The attempt at a solution For part a, I was able to find thermal data for fissile nuclides (Table 3.4) and was able to come up with this solution: I however can not find any relevant data to perform part b. I am a bit confused as to how to approach this last portion. Any help and guidance would be truly appreciated.
