“…Here we intended to perform simulations of irradiation of series of G3 glasses, in order to interpret experimental data published recently [20,30,21,19] and produced within the scope of this paper (NBS4 glass). The computational procedure is tested on data on irradiated PNL 76-68 glass [17,46].…”

“…However, due to safety concerns, it is necessary to estimate the parameters of borosilicate glass under residual irradiation. In the past years, many groups have extensively studied the thermodynamic, chemical and mechanics properties of borosilicate glasses and significant experimental effort has been devoted to understand the evaluation of the properties of irradiated borosilicate glasses [16,17,18,19,20,21,22]. Yet, these experimental results require detailed interpretation, which could be achieved by correct understanding of the atomic scale processes associated with radiation damage and defects accumulation.…”

Properties of irradiated sodium borosilicate glasses from experiment and atomistic simulations

With a combination of atomistic modeling and experimental techniques we have investigated the structural and elastic parameters of sodium borosilicate glasses, including irradiation-induced changes. Both approaches show that the Young's modulus depends linearly on the density of material. The simulated glass density and boron speciation match also the estimates by independent, elemental glass composition-based models, indicating that atomistic simulations could be used in validation of theoretical models and experimental results. This allows us to formulate Young's modulus -density relationships for investigated borosilicate glasses and test the existing empirical model for description of Vickers hardness of these materials. The simulation of irradiation reveals a change of B [4] content under irradiation. By applying a simple defects accumulation procedure we are able to

“…Similarly, from many external ion irradiation studies [10,14,[25][26][27][28][29] the changes in various material properties have been observed to occur which usually saturate after 4×10 20 to 4×10 22 keV.cm -3 (either in nuclear or electronic energy dose). For instance, heavy-ion irradiations have been observed to: (i) decrease the hardness (by about 35 % in French Nuclear Waste Surrogates (F-NWS) and by about 13 to 36 % in Chinese-NWS (C-NWS) depending on the glass composition); (ii) decrease/increase the modulus (decrease by about 15-20 % in F-NWS, increase by about 4 % in sodium-aluminoborosilicates (C-NWS) and decrease by about 18 % in sodium borosilicates (C-NWS)); and, (iii) decrease the density (by about 1.5 % and 3 % for French SON68 and BS3 glasses respectively) [14].…”

Due to the complexities associated with handling and characterizing the radiation damage in radioactive materials such as nuclear waste forms, ion irradiation has been widely used to simulate the effects of the selfirradiation damage. This often involves ion irradiation of nuclear waste surrogate glasses using ion accelerators. Such facilities allow using a wide range of ion types ranging from H to U and energies from tens of keV to hundreds of MeV. For various reasons, the researchers often have to use ions and energies that do not necessarily match with what is expected in actual nuclear waste forms. Due to a lack of detailed and dedicated studies, there are currently no guidelines or consensus regarding the use of the ion irradiation as a means of simulating the self-irradiation damage. The purpose of this article is to delve into this subject by presenting systematic studies of a number of glasses carried out in the last decade or so. By doing so, guidelines and easy to follow ion-mass Vs ion energy contour maps are provided to best simulate the long-term radiation damage in nuclear waste forms. We also discuss how the ions of different masses and energies can be exploited for defect healing and provide a roadmap to undertake systematic studies on this subject. For the sake of brevity, a quick summary of important results and the guidelines is presented towards the end of this article and not here. Besides the nuclear waste community, the study is also of interest to a wide research community dealing with defect formation and defect healing in glasses for use in radiation environments experienced in nuclear reactors, decommissioning and space applications to name a few.
