The enhancement of heat transfer from fuel rods to coolant of a Liquid Metal Fast Reactor (LMFR) decreases the fuel temperature and, thus, improves the safety margin of the reactor. One of the mechanisms that increases heat transfer consists of large coherent structures that can occur across the gap between adjacent rods.

A Hybrid Spline Difference Method is developed to solve a nonlinear equation of welding problem in ultrasonic welding. It is shown that the method has a computational procedure as simply as the finite difference method. In addition, the proposed method can simplify complexity of the traditional spline method calculation, and increase accuracy of the first and second derivatives of space from O(Tx 2 ) of finite difference method to O(Tx 4 ).

The effect of mass flow rate, volume concentration inlet temperature on heat transfer rate with varied coolant mass flow rate ranging from 6LPM, 8LPM, 10LPM were examined. Results shows that heat transfer rate linearly increases with increase in mass flow rate and volume concentration, the best heat transfer rate is achieved at 0.3% volume fraction of CuO at 10LPM. A maximum enhancement of 35% in heat transfer rate is obtained for 0.3% concentration of CuO nanofluid.

The convective heat transfer coefficient was improved up to 23.84% by using TiO2 nanofluids instead of the base fluid. It was found that TiO2 nanofluid with a volume fraction of 0.3% (at a mass flow rate of 0.0689 kg/s) will provide the maximum efficiency enhancement in the PTSC (9.66% higher than the water-based collector). Consequently, the absorbed energy parameter was found to be 10.3% greater than that of the base fluid.

The wire-wrapped fuel bundle is an assembly design in a sodium-cooled fast reactor. A wire spacer is used to maintain a constant gap between rods and to enhance the mixing of coolants. The wire makes the flow complicated by creating a sweeping flow and vortex flow. The vortex affects the flow field and heat transfer inside the subchannels.
