Problem 4.9 -- Assuming a recoverable energy per fission of 200 MeV, calculate the fuel burnup and consumption rates in g/MWd for (a) thermal reactors fueled with 233 U or 239Pu; (b) fast reactors fueled with 239Pu. [Note: In Part (b), take the capture-to-fission ratio to be 0.065.] [Partial Ans. (a) For 233U, consumption rate = 1.138 g/MWd; for 239Pu, 1.46 g/MWd; (b) 1.141 g/MWd]
