To reduce SNF cask failure risk in the ISFSF building areas, where SNF cask could be lifted more than 30 cm, special design shock absorbers are installed. The main function of these shock absorbers is to reduce the dynamic loads to a fully loaded SNF cask (weight 77 - 89 t) in case of dropping and prevent or minimise the possibility to lose the tightness of the SNF cask and release of radioactive materials from SNF rod(s). Evaluation of the shock absorbers capability to withstand the dynamic load in case of an accident was performed.

Ph.D. student Noura Elsalamouny (Lithuanian Energy Institute, Laboratory of Nuclear Installation Safety) participated in Summer School 2021 “Modelling, Experimental and Validation” (MeV) organized through the cooperation of multiple stakeholders, i.e. Argonne, Idaho and Oak-Ridge national labs. Noura worked in a team together with other students and presented joint work titled “The at-home micro reactor”. This futuristic idea was investigated in terms of the conceptual goals set, the necessary safety requirements, the design constraints, and the economic benefits of a micro-reactor installed at-home.
