A homogeneous thermal cylindrical reactor core is D=4 ft diameter and H=4 ft high. The extrapolation lengths in all directions are 0.5 ft. Use following values for calculation. N-61020 atoms/cm, co-1013 neutrons/cm. sec, Tmod=500F. (a) Find the volumetric power density (q") in W/m unit at a point 0.832 ft radial distance and 1.667 ft above the center of the core. (b) Assume that DO coolant at 120 bars is flowing over the core with inlet temperature at 230 C with velocity of 2 m/sec. The equivalent hydraulic diameter is 1.2 m. What is the bulk temperature at the axial location of H=1.667 ft? What is the heat transfer coefficient at this location? Use following values of =110-4 Pa-sec, c=4200 J/kgC, p=800 kg/m, k=0.6 W/mK. (c) What is the DO temperature at channel outlet? Discuss if this temperature is realistic.
