“…For example, Transmission Electron Microscopy (TEM) studies of both neutron and ion irradiated UO 2 have been widely conducted to understand the development and evolution of gas bubbles and their size distribution in UO 2 [4][5][6][7][8][9][10][11][12][13][14]. However, in situ TEM observations of dynamic bubble evolution in UO 2 is still lacking [13].…”

“…However, in situ TEM observations of dynamic bubble evolution in UO 2 is still lacking [13]. In addition, there is a lack of literature focusing on Kr and Xe distribution and stoichiometry change in UO 2 under ion irradiation [14]. It is well known that the stoichiometry change of UO 2 could have a strong impact on its thermal conductivity.…”

In situ and ex situ transmission electron microscopy observation of small Kr bubbles in both single-crystal and polycrystalline UO 2 were conducted to understand the inert gas bubble behavior in oxide nuclear fuel. The bubble size and volume swelling are shown as weak functions of ion dose but strongly depend on the temperature. The Kr bubble formation at room temperature was observed for the first time. The depth profiles of implanted Kr determined by atom probe tomography are in good agreement with the calculated profiles by SRIM, but the measured concentration of Kr is about 1/4 of the calculated concentration. This difference is mainly due to low solubility of Kr in UO 2 matrix and high release of Kr from sample surface under irradiation.

“…10a) some clustering is seen but with no clear voids/bubbles lines identification over a long range. As discussed in [18], this indicate that voids/bubbles are generated by a synergetic effect of both, high electrical stopping power and high temperature. The different change in the bulk structure as a result of the I-irradiation at the two temperatures could arises from activation of uranium and oxygen vacancies migration in the same temperature interval [9], i.e.…”

“…Irradiation experiments were performed at the 15 MV ALTO Tandem accelerator facility, at the Nuclear Physics Institute (IPN, Orsay, France) with heavy ions: sulfur and iodine ions (any atom consisting of more than twenty nucleons is considered as "heavy") at the same 9 + charge. We used an experimental irradiation chamber described in a previous paper [25] to maintain the pressure at around 10 −6 mbar. The irradiation conditions are summarized in Table 1 .…”
