Floating Nuclear Power Plant Risk Based New Technology Qualification Applied for SMR Application

Abstract This paper aims to present a risk-based technology qualification approach for the construction and deployment of transportable nuclear power plants (TNPPs) and floating nuclear power plants (FNPPs) using small modular reactors (SMRs). The scope includes exploring the potential of leveraging existing codes and standards from the marine and offshore oil and gas sectors. The proposed approach draws from the experience of floating liquefied natural gas projects from around 2010 or so. lt involves identifying the components that will be designed, built, installed, operated, maintained, and decommissioned in different environments; codes; and supply chains compared to traditional land-based nuclear facilities. Subsequently, the necessary technology qualification activities will be assessed. This methodological approach helps evaluate the risks associated with non-traditional construction and siting approaches for SMRs and provides a framework for managing those risks. The paper will present the results of applying the risk-based technology qualification approach to the construction and deployment of SMRs using non-traditional methods. It is expected to demonstrate the potential benefits and challenges of leveraging existing codes and standards from the marine and offshore oil & gas sectors for SMR projects. The observations will likely highlight the key areas where technology qualification activities are crucial, such as component design, material selection, fabrication processes, and operational considerations. The conclusions will emphasize the importance of a systematic approach to identifying and addressing risks associated with nontraditional construction and siting approaches for SMRs. The proposed methodology can help streamline the deployment process and ensure that SMRs meet the necessary safety and regulatory requirements while benefiting from the advantages of factory built and transportable designs. This paper will contribute novel insights into the application of risk-based technology qualification approaches for the construction and deployment of SMRs using non-traditional methods. It will provide a framework for leveraging existing industry knowledge and standards, potentially accelerating the deployment of SMRs and unlocking their promised benefits.
