Heat and Mass Transfer during Hydrogen Generation in an Array of Fuel Bars of a BWR Using a Periodic Unit Cell

<table>Temporal evolution of the average temperatures in the system taking initial temperature distributions of 557.5 K, 563 K and 1169.5 K for the coolant, cladding, and fuel regions, respectively. The heat source term was fixed as 3403.569 W/m<sup>3</sup>; the average fluid velocity is 0.7045 m/s.</table>
