5-5. A spherical reactor core is 5 ft in diameter. It contains 20 percent enriched UO, spherical fuel pellets 1 in. in diameter each. In one of these pellets, the temperature drop from center to edge of fuel is 3000°F. The maximum flux in the core is 10¹3. What is the radial position of this pellet? Neglect extrapolation lengths. Take kf = 1.1 Btu/hr ft °F, fuel density = 11 m/ cm³, o=500 b.
