Problem 2.021 Uniform internal heat generation at 2.00 x 107 w/m3 is occurringn a cylindrical nuclear reactor fuel rod of 40-mm diameter, and under steady-state conditions the temperature distribution is of the form a+ti,where r is in degrees Celsius and r is in meters, while-800 C and-1.667 x 10s .C/m2. The fuel rod properties are a-30 W/m K e-1100 kg/m3, and 800 J/kg K. Step 1 Find the steady state temperature gradient at the outer surface of the rod, in C/m the tolerance is +/-2% By accessing this Question Assistance, you will learn while you earm points based on the Point Potential Policy set by your instructor Step 2 What is the steady state rate of heat transfer at the outer surface,n W/m? W/m the tolerance is +/-2% By accessing this Question Assistance, you will learn while you earn points based on the Point Potential Policy set by your instructor Step 3 What is the steady state rate of heat transfer at the centerline, in W/m W/m the tolerance is +/-2% By accessing this Question Assistance, you will learn while you earm points based on the Point Potential Policy set by your instructor Step 4 Immediately after the sudden increase in reactor power level to4 1 108 W/m3 (atr- O sec), what is the temperature at the centerline, in C the tolerance is +/-29 By accessing this Question Assistance, you will learn while you earm points based on the Point Potential Policy set by your instructor Step 5 Immediately after the sudden increase in reactor power level to 1x 108 W/m3 (atr O sec), what is the time rate of temperature change at the centerline, in °C/s?
