SMR Digital Twin

- Overview

Digital twins are virtual, dynamic models of physical systems that can be used to simulate and analyze their behavior. 

In the context of nuclear energy, particularly small modular reactors (SMRs), digital twins offer a powerful tool for enhancing safety, efficiency, and maintenance. 

By creating virtual replicas of SMRs, digital twins can predict potential issues, optimize operations, and even train personnel, all without requiring physical access to the reactor.

Digital twins are a promising technology for the nuclear industry, particularly for SMRs. By providing a virtual representation of the physical system, digital twins can enhance safety, efficiency, and security, potentially leading to a more reliable and cost-effective energy source.
