Luis is pursuing research regarding the Scalable LIquid Metal cooled small Modular (SLIMM). SLIMM is a natural circulation, sodium cooled reactor that will provide power from 10s to a few 100s MWe to small or isolated communities. The advantages of this reactor include its capabilities to be built and assembled in the factory and shipped to the construction site by rail, heavy trucks, or on barges, and at its end of life it could be easily replaced by a new unit. Luis' research involves thermal-hydraulic modeling of the reactor, natural circulation system, neutronics, and the passive system of decay heat removal after shutdown.
The analysis of the SMR is carried out using the Computation Fluid Dynamics packages STAR-CCM+ and SolidWorks Simulation for the thermal-hydraulics, Monte Carlo radiation transport code MCNP6 for the neutronics, and MATLAB for the transient analysis of the decay heat removal.
