[Problem 15-5, p.679 in Henry and Heinke.] Some of the important characteristics of each of the reactors at the Pickering Nuclear Generating Station are as follows:

                        Thermal output: 1744 MW

                        Number of fuel channels: 390

                        Fuel bundles per channel: 12

                        Uranium content per fuel bundle: 19.8 kg

                        Total weight of fuel bundle: 23.7 kg

                        Length of fuel bundle: 49.5 cm

                        Outside diameter of fuel bundle: 10.2 cm

                        Average burnup of fuel: 7500 MWd thermal/tonne U

Assume that each reactor achieves a capacity factor [CF] of 0.8, where CF = (Actual energy

produced) / (Perfect production). Calculate:

a)   The number of new fuel bundles per reactor required for each day of operation.
