Digital Twin

Enabling simulation verification, physical system control and analysis of trends using computation simulations via AI and machine learning.

Digital Twins represent the merging of digital thread, controls theory, artificial intelligence, and online monitoring into a single cohesive unit, a virtual model that comprehensively captures all relevant aspects of the underlying system, utilizing bidirectional communication to track and trend both simulated and measured physical responses. This enables continuous improvement of the models to gain the greatest insight into process performance and optimization. By utilizing open-source model integrations and data stores, our digital twins provide the greatest value by utilizing existing models to their greatest extent while avoiding undesirable and costly vendor lock-in.

Collaborations & Projects:

The cost of failing to create sufficiently integrated digital engineering systems for large-scale projects is abundantly evident in the nuclear industry and elsewhere. For example, the European Aeronautic Defense & Space (EADS) Airbus 380 program suffered approximately $6.1 billion in losses due to a lack of data integration between design applications used by the various teams. This software interoperability issue caused 20 months of delays and a loss in program confidence (https://www.cadalyst.com/cad/product-design/what-grounded-airbus-a380-10903). On the other hand, when the digital thread is enabled, many positive outcomes will follow. General Electric Digital lists positive outcomes of digital twins including 93–99.49% increased reliability, 40% reduced reactive maintenance, 75% reduced time to achieve outcomes, and the avoidance of $11 million lost in production by detecting and preventing three failures (https://www.ge.com/digital/applications/digital-twin).

Defense Nuclear Nonproliferation (DNN) Program

The development of new advanced reactors (Gen IV) increases the importance of new methods to understand diversion and misuse scenarios, and determine mitigation pathways. INL is developing a complete digital twin framework for safeguards by design. This provides the opportunity for comprehensive understanding of nuclear fuel cycle facility operations to significantly strengthen nuclear safeguards and nonproliferation regime.

Capabilities: 

Diamond (Data Integration Aggregated Model and Ontology for Nuclear Deployment)

DIAMOND is a nuclear ontology. An ontology is a collection of concepts and relationships within a given domain. It is an extensible document that contains the classes, properties, and relationships that make up that domain. DIAMOND is a Web Ontology Language (OWL) document. OWL is an extension of XML that provides the ability to represent the various constructs in an ontology. DIAMOND acts as a standard taxonomy for the nuclear domain by which data sources can be integrated together through a common format. While DIAMOND is only a data model, when acting as the central schema for Deep Lynx it enables a model to which all integrating data sources can be mapped. https://github.com/idaholab/DIAMOND.

Deep Lynx

A data warehouse technology that can enable the digital thread across an organization by serving as the central point of data aggregation and exchange. Deep Lynx is built on the relational database PostgreSQL, but stores data in a graph-like format. This enables data to be exported to graph databases for analysis and for data to be queried in a graph-like format. When a data source sends data to Deep Lynx, that data is mapped to a central schema (or ontology) in Deep Lynx. This central schema creates a common data format to which all data is mapped. https://github.com/idaholab/Deep-Lynx.

RAVEN

RAVEN (https://raven.inl.gov) is a flexible and multi-purpose probabilistic risk assessment, uncertainty quantification, artificial intelligence, data analysis and model optimization framework. Depending on the tasks to be accomplished and, in case, on the probabilistic (or not) characterization of the problem, RAVEN perturbs (e.g., Monte Carlo, Latin hypercube, reliability surface search, AI-guided, etc.) the response of the system to be analyzed altering the input parameters. The system is modeled by third party software (e.g. RELAP5-3D, MAAP5, BISON, etc.) and accessible to RAVEN either directly (software coupling) or indirectly (via input/output files). The outcomes of the sampling process are analyzed using statistical and data mining approaches. RAVEN also manages the parallel dispatching (i.e. both on desktop/workstation and large HPC systems) of the software representing the physical model. RAVEN relies on artificial intelligence algorithms to construct surrogate models of complex physical systems to accelerate the analysis. RAVEN can be employed for several types of applications, such as UQ, Sensitivity Analysis, PRA, Regression Analysis, Data Mining, Model Optimization, and design of experiments. An overview of the software is resented at raven.inl.gov. The software itself is open-source and can be downloaded at https://github.com/idaholab/raven
