Question: A BWR core operates at 7.0 MPa and generates 5000 MWt. Core dimensions and parameters are Number of rids: 70000, rod lengths: 4.5 m, rod

A BWR core operates at 7.0 MPa and generates 5000 MWt. Core dimensions and parameters are Number of rids: 70000, rod lengths: 4.5 m, rod outer clad diameter: 1.14, inlet flow velocity: 8 m/s, lattice pitch: 1.24 cm, and inlet temperature: 275 C.

Assume a sinusoidal axial power distribution:

Assuming a constant heat flux condition:

a. Find the temperature as a function of core height (h) and determine the saturation height.

b. Compute the pressure loss in the single-phase region due to gravity, friction, and then the total, each as a function of height (h).

c. Using the saturation height as the onset of nucleate boiling, compute the pressure loss in the two-phase region due to gravity, friction, acceleration, and then the total, each as a function of height (h).
