Small modular reactors (SMR) are of growing interest, the regional geological situation determines whether such objects can be safely situated in any specific area. The dynamic progress of climate change in boreal regions, such as the Baltic States, may endanger the structural integrity of SMR. Soil shear strength and stiffness during warmer winters and more often freeze-thaw cycles, increasing moisture, might significantly influence the instability due to over consolidation in some parts under the structure, activation of possible sliding planes between various layers (especially varved clays), resulting in the risk of structural settlement and instability, also higher corrosively. Studies must include all kind of risk assessment regards geotechnics, environment and logistics.
