Considerations of Geothermal Aspects for SMR Installation in Northern Permafrost Lands

Abstract

Permafrost degradation amplified by climate change is one of the key issues to consider when attempting to install an SMR in the remote communities of northern Canada. If thermal disturbance of permafrost takes place, the strength of the ground may be reduced, resulting in structural settlement and stability problems. Therefore, when constructing an SMR in permafrost soils or bedrocks, local permafrost conditions must be protected around the foundations. In the present work, a state-of-the-art literature review has been performed on the geothermal aspect of permafrost heat balance and its effects on the foundation when considering the SMR installation. Based on the current standards by Standards Council of Canada and various foundation design manuals developed for northern infrastructure, recommendations are given on the geothermal analyses to predict the interaction of the proposed SMR building with permafrost at the site for different life-cycle phases. This study will help ensure the long-term performance of SMR structures under changing environmental conditions.
