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- \(1.31 \mathrm{~cm}\).
