We would like to load a core with fuel rods in which fuel
pellet enrichment is such that the neutron flux increases linearly along the
vertical axis as shown in the figure. Water is used as coolant. Use the given
data

and find a) water temperature at the exit of the channel, b)
peak temperatures of clad outside, clad inside, fuel surface, and fuel center,
c) the incipient boiling temperature, and d) critical heat flux at the channel
exit.
