Uniform versus Nonuniform Axial Power Distribution in Rod Bundle CHF Experiments

<table>Rod bundle CHF with nonuniform APD. With the example of cosine axial power distribution, under normal operating condition and similar mixing vane grid and similar grid span at each elevation, the CHF mostly occurs near 2/3 elevation of the entire heated length.</table>
