NRC Expands its International Memorandum of Cooperation to Include UK Regulator

March 12, 2024

The NRC expanded its previous international cooperation agreement with the Canadian Nuclear Safety Commission (CNSC) to now also include the United Kingdom Office of Nuclear Regulation (ONR).  This Memorandum of Cooperation (MOC) is intended to result in increased collaboration on the technical reviews of advanced reactor and small modular reactor technologies. Under the terms of this MOC, CNSC, ONR, and U.S. NRC may take each others’ experiences, regulatory information and results into account when conducting technology assessments for the purposes of feedback to vendors or making recommendations for regulatory decisions.  More information regarding this collaboration, including past and ongoing activities, and responses to frequently asked questions, can be found at:
