“…The observation also supports that neutron irradiation tends to increase agglomeration and this agglomeration is more prominent at higher concentrations resulting in the larger decrease in thermal conductivity at higher concentrations. It has also been suggested that the bombardment of neutrons on a material induce defects [28] and vacancies [41] apparent from UV-vis spectra ( figure 6). Further, the decrease in thermal conductivity is more prominent with increased duration of radiation exposure.…”

In this work, the thermal conductivity of Al 2 O 3 nanofluids has been investigated for the sensitivity towards neutron irradiation. The solution combustion method has been used for the synthesis of Al 2 O 3 nanoparticles that have been used for the preparation of the nanofluids. Prepared nanofluids have been neutron-irradiated for 7 and 14 days. Dynamic Light Scattering, Scanning Electron Microscopy, and Ultraviolet-Visible Spectroscopy have been used to ascertain the change in properties before and after neutron-irradiation. Thermal conductivity has been measured for un-irradiated and neutron-irradiated nanofluids at 30°C using a KD2 pro thermal properties analyzer. The decrease in thermal conductivity has been observed after neutron-irradiation that further decreases with increased duration of exposure and concentration of nanoparticles. 5 and 10% decrease in thermal conductivity has been recorded after 7 and 14 days of neutron irradiation for change in concentration from 0 to 2 volume percent. Neutronirradiation sensitivity analysis revealed that heat transfer characteristics are sensitive at higher concentrations and during initial exposure of neutron-irradiations.
