Question: PWR and PHWR use Uranium oxide fuel. Compute and compare the average linear heat rating (LHR) (mathrm{W} / mathrm{m}) and heat flux at clad surface

PWR and PHWR use Uranium oxide fuel. Compute and compare the average linear heat rating (LHR) $\mathrm{W} / \mathrm{m}$ and heat flux at clad surface $\mathrm{W} / \mathrm{cm}^{2}$ of the two types of reactors based on following data:

PWR: Power-3410 MWt, number of fuel rods-51000, fuel rod active length-366 cm, and rod outer diameter- $0.95 \mathrm{~cm}$.

PHWR: Power-2160 MWt, number of fuel channels-392, fuel rod length in a bundle-$49.5 \mathrm{~cm}$, number of rods in a bundle-37, number of bundles in a channel-13, and rod outer diameter- $1.31 \mathrm{~cm}$.
