Developing the necessary structure and capabilities of a regulatory body for a comprehensive, independent safety assessment of NPP designs needs substantial time and resources. In many cases, neither sufficient time nor sufficient resources will be available for countries embarking in nuclear power now with the aim to supply carbon free energy in the near future. The panel members will present and discuss various options for the use of Third-Party oversight of design, construction and operation with a particular focus on how the deployment of nuclear power reactors can be enabled for newcomer countries. Examples of options to be discussed are: the model already established by Lloyd's Register in the shipping industry as pseudo-regulators for design, construction, and operation, with some experience in the assurance of nuclear-powered submarines; a concept for an Independent Technical Support Organization funded by major national regulatory bodies; a concept for a Third-Party review funded by the reactor vendor; a concept for the informed adoption of safety assessments or design approvals by well-established regulatory bodies. The role international organizations could play in these approaches will also be addressed.
