Use of nanofluids for LWR safety and economics enhancement
Colloidal dispersions of nanoparticles are known as ‘nanofluids’. Such engineered fluids offer the potential for enhancing heat transfer, particularly boiling heat transfer, while avoiding the drawbacks (i.e., erosion, settling, clogging) that hindered the use of particle-laden fluids in the past. We have been studying the basic heat transfer characteristics of nanofluids, i.e., thermophysical properties, single-phase convective heat transfer, boiling heat transfer (including pool and flow CHF), and quenching heat transfer. Furthermore, we have been evaluating the benefits of nanofluids for and applicability to nuclear power systems, i.e., primary coolant in PWRs, safety systems (ECCS) for both PWRs and BWRs, severe accident mitigation strategies (In-Vessel Retention).
