Heat transfer in the fuel-clad gap in a nuclear reactor impacts the overall temperature distribution, stored energy and the mechanical properties of a nuclear fuel rod. Therefore, an accurate estimation of the gap conductance between the fuel and the clad is critically important for reactor design and operations. To obtain the requisite accuracy in the gap conductance estimation, it is important to understand the effects of the convective heat transfer coefficient, the gas composition, pressure and temperature, and so forth.

520 $a Heat transfer in the fuel-clad gap in a nuclear reactor impacts the overall temperature distribution, stored energy and the mechanical properties of a nuclear fuel rod. Therefore, an accurate estimation of the gap conductance between the fuel and the clad is critically important for reactor design and operations. To obtain the requisite accuracy in the gap conductance estimation, it is important to understand the effects of the convective heat transfer coefficient, the gas composition, pressure and temperature, and so forth.
520 $a The objectives of this study are to build a bench-scale experimental apparatus for the measurement of thermal gap conductances and to develop a better understanding of the differences that have been previously observed between such measured values and those predicted theoretically. This is accomplished by employing improved analyses of the experiments and improved theoretical models.
520 $a Using laser heating of slightly separated stainless-steel plates, the gap conductance was measured using a technique that compares the theoretical and experimental time dependent temperatures at the back surface of the second plate. To consider the effects of surface temperature and gas pressure, the theoretical temperatures were calculated using a convective heat transfer coefficient that was dependent upon both the temperature and the gas pressure.
