Abstract: There is a growing interest in Small Modular nuclear Reactors (SMRs) driven mostly by the concerns in decarbonising the electricity and heat sectors. Despite the expected advantages of SMRs with respect to large reactors (e.g. construction schedule reduction, lower upfront investment per unit) and at least two decades of studies, investments in SMRs have been extremely limited. Leveraging a literature review, in-depth discussions, and a questionnaire survey, this paper aims to identify and rank general elements hindering SMR construction, specific licensing and regulatory elements affecting SMR construction, and elements favouring or hindering the reuse of SMR modules. The results show that financial and economic issues (including perceived investment risk, availability of cheaper technologies to generate electricity) are the main barriers for SMR construction. Government support for financing the first-of-a-kind and developing a supply chain could allow overcoming these barriers. Time, cost and risk of the licensing process are critical elements for SMR construction; therefore, policies should be in place to support stakeholders. The economic feasibility can hinder the opportunity of reusing SMR modules. Design and interface standardisation are the main enabling factors of reusing SMR modules. Further studies on SMR decommissioning through a "circular economy" lens are needed.
