Nuclear reactor analysis. A nuclear fuel rod is generating heat and is in the shape of a cylinder of radius \(R\). The surface is losing heat with a heat transfer coefficient of \(h\) to the surrounding coolant. What is the maximum temperature in the rod as a function of the system parameters? If there is a reduction in the coolant (water to generate steam) flow, is there a chance of meltdown? Investigate the conditions for meltdown.
