This document identifies a number of issues of particular importance to light water Small Modular Reactors (SMRs), which are not currently adequately addressed by existing IEC SC 45A standards, and that could be considered when revising existing publications or that could be the object of new work item proposals. Whether each of these issues will indeed be addressed, and if so in which publication, will be the decision of each SC 45A working group.

Though there are a number of advanced Generation IV SMR projects underway, their specific needs are not covered by this document.

This document is organized as follows:

  • Clause 5 presents the main features of SMRs that are not typically found in large reactors or that are of particular importance for SMRs, and that could require specific or additional requirements and recommendations over those already provided in IEC SC 45A standards.

  • Clause 6 suggests, for each working group, a number of issues that could be considered in the revision of existing publications or as subjects for new work items.

  • Clause 7 suggests topics of importance to SMRs but that do not fit in the current scope of existing working groups.
