To facilitate the development of molten salt reactor technologies, a fundamental understanding physical and chemical properties salts under combined conditions high temperature intense radiation fields is necessary. Optical spectroscopic (UV-Vis-near IR) electrochemical techniques are powerful analytical tools to probe molecular structure, speciation, thermodynamics, kinetics solution dynamics. Here, we report design fabrication three custom-made apparatus: (i) multi-port...
Room temperature post-irradiation measurements of diffuse reflectance and EPR spectroscopies were made to characterize the long-lived radiation-induced species formed upon gamma irradiation (up 100 kGy) solid KCl, MgCl<sub>2</sub>, ZnCl<sub>2</sub> salts.
The generation and stabilization of gamma radiation-induced hydrogen atoms in gibbsite (Al(OH) 3 ) nanoplates is directly related to the nature residual ions from synthetic precursors used, whether nitrates or chlorides.
Chromium (Cr) is a frequent constituent of the metal alloys proposed for molten salt nuclear reactor (MSR) applications, and typically least noble ion present. Consequently, chromium preferentially corroded into solutions. The redox poise cycling ions in can greatly influence its corrosivity towards structural alloys, ultimately impacting longevity MSR systems. Radiation-induced chemistry expected to play significant role determining oxidation state distribution during operations. In present...
Silicone rubber films were modified by the consecutive grafting of 2-(diethylamino)ethyl methacrylate (DEAEMA) and N-vinylcaprolactam (NVCL) using direct method on two steps with gamma-rays. The effect absorbed dose monomer concentration degree was determined. grafted samples verified FTIR-ATR spectroscopy swelling; thermal properties analyzed DSC TGA. stimuli-responsive behavior studied swelling and/or DSC. Thermo- pH-sensitive (PP-g-DEAEMA)-g-NVCL presented a pH critical at 3.2 LCST around 63.5℃.
The electron paramagnetic resonance and diffuse reflectance-optical absorption spectra of room-temperature γ-irradiated KCl–MgCl2 binary solid salt mixtures (98:2 mol % 2:98 %) the eutectic (68:32 are reported. Additionally, powder X-ray diffraction pristine salts thermal annealing studies irradiated were performed to evaluate radiolysis product stability, annihilation, association in metallic particles. main long-lived transient species detected 98:2 perturbed F-centers, that is, trapped...
