Consider an ideal core with the following characteristics: The U-235 enrichment is uniform throughout the core, and the flux distribution is characteristic of an unreflected, uniformly fueled cylindrical reactor, with extrapolation distances z and R of 10 cm. How closely do these assumptions allow prediction of the following characteristics of a PWR? 1. Ratio of peak to average power density and heat flux? 2. Maximum heat flux? 3. Maximum linear heat generation rate of the fuel rod? 4. Peak-to-average enthalpy rise ratio, assuming equal coolant mass flow rates in every fuel assembly? 5. Temperature of water leaving the central fuel assembly? (Page 156)
