Advances in Cybersecurity by Design Leveraging Complementary Frameworks of CIE and TCA

Current regulations for the existing U.S. nuclear fleet prescribe a Òwrap-aroundÓ security approach for cybersecurity. The cybersecurity protections are based on strict access control and configuration management, defended by strong physical protection measures (i.e., guns, guards, and gates).Ê While this wrap-around approach has been sufficient in securing existing nuclear power plants (NPPs) from cyber-attacks, it constrains innovation and new, novel use cases (e.g., remote, autonomous operations) that are necessary to drive capital and operating costs of new Small Modular Reactors (SMRs).
