The core of an lmfbr consists of a square lattice of 13, 104 fuel rods that are 0.158 in in diameter, 30.5 in long, on a 0.210-in pitch. the fuel rods are 26 w/o-enriched uranium clad in 0.005-in stainless steel. liquid sodium enters the core at approximately 300°c and passes through the core at an average speed of 31.2 ft/sec. the core produces 270 mw of thermal power, with a maximum-to-average power density of 1.79. calculate: (a) the maximum heat production rate; (b) the maximum neutron flux.
