Question

At the start of a reactor cycle following a reload refueling, a fuel assembly has a burnup of 22.4 MWd/kg. The fuel assembly averages a power of 94% that of the core average fuel assembly power over the 426 calendar days of cycle operation. At the end of the cycle, the fuel assembly’s burnup is 36.7 MWd/kg. The reactor is rated at 2800 MWt full power. It contains 157 fuel assemblies, each with an initial fuel loading of 500 kg.

(a) What was the fuel assembly’s cycle burnup in MWd/kg?

(b) What was the cycle burnup in MWd/kg?

(c) How many effective full power days (EFPD) did the cycle operate?

(d) What was the cycle’s capacity factor?
