Nuclear energy: enabling production of food, fiber, hydrocarbon biofuels, and negative carbon emissions
In the 1960s, Alvin Weinberg at Oak Ridge National Laboratory initiated a series of studies on nuclear agro-industrial complexes1 to address the needs of the world’s growing population. Agriculture was a central component of these studies, as it must be. Much of the emphasis was on desalination of seawater to provide fresh water for irrigation of crops. Remarkable advances have lowered the cost of desalination to make that option viable in countries like Israel. Later studies2 asked the question, are there sufficient minerals (potassium, phosphorous, copper, nickel, etc.) to enable a prosperous global society assuming sufficient nuclear energy? The answer was a qualified “yes,” with the caveat that mineral resources will limit some technological options. These studies were defined by the characteristic of looking across agricultural and industrial sectors to address multiple challenges using nuclear energy.

This paper discusses the estimation of heat transfer characteristics using different SiO2 nanofluid conditions on a downward-facing heating surface. Two sizes of SiO2 nanoparticles (20 and 50 nm) were selected for the nanofluids. The influence of the critical heat flux (CHF) for different nanofluid concentrations was also compared and investigated. We observed that the CHF changed with the concentration of nanofluids, which reached the maximum enhancement at 0.1 g/L but decreased at 0.12 g/L. Compared with reverse osmosis water, the 50- and 20-nm SiO2 nanofluids exhibited enhancements of approximately 43% and 49%, respectively. The heating surface was characterized and the deposition of nanoparticles was observed. After pool boiling, the wettability of the heating block and the roughness changed. As the concentration increased, the CHF decreased after attaining the maximum value, which was due to the characteristics of the downward-facing heating surface and the decrease in the nucleation points on the heating block surface.
