45. The power distribution in the axial direction of the 12-ft-long fuel rods of a PWR is well represented by q"" = constant x cos(лz/144), where z is in inches. The minimum DNBR is 2.1 and occurs 90 in up the hottest channel, where the critical heat flux is computed to be 1.08 x 106 Btu/hr-ft2. The hot channel factor for the reactor is 2.78, and the total heat transfer area is 48,000 ft². Calculate (a) qmax; (b) qav; (c) the operating power of the reactor.
