- 3. Real-Time Simulator • Real-time simulators came to the nuclear industry as training tools in the 1970s – Full plant modeled, but models often “hand crafted” – Analog controls, traditional hard-panel control panels • Today’s nuclear power plant simulator is high fidelity – Same scope, but – High-definition predictive models used to model plant systems – Digital controls and modern HSIs: detailed view of systems • Today the real-time simulator is an engineering tool – Holistic dynamic plant model 3
- 4. Real-Time Simulator • Broad or full-scope plant model – Includes primary, secondary, BOP and safety system and at least a high-fidelity main loop • All models integrated and synchronized (coupling) • One second of problem time = One second of real time (feels like the real plant) • Models are interactive – Observe and operate like the real plant – Can be integrated with real control systems 4
- 5. New Missions of Simulator • Holistic engineering V&V platform − Validation of system design issue in integrated “plant” • Controls system design and V&V − Validation and refinement of logic and controls strategies as a development tool for new control strategies • Human factors engineering platform − Support design of DCS interface, alarms, procedures, etc. − Support design of digital control rooms and information layout − Demonstrate viability of these designs to regulator • Develop and validate operating procedures • Address post-Fukushima challenges 5

Editor's Notes
- A popular term for describing the new role of the simulator is Simulator Assisted EngineeringFor many of these new plants, the simulator is their first view of the plant running. It provides an Integrated Environment testing out design assumptions.For years simulators have been used to test the DCS implementation in non-nuclear applications, finding issues with control strategies as well as bugs in implementing the DCS when it is less costly to fix.From a human factors perspective, operating a nuclear plant almost totally from computer screens versus panel boards is a “radical” change. Presenting the right level of information, determining the navigation and conduct of operations, and testing out new operator aids such as electronic procedures and alarm handling systems are all effective uses of the simulator.For many of the new plants, operating procedures just don’t exist and the simulator is a perfect tool for developing the procedures and corresponding training materialsFinally at the end of the day, you also have your ANS 3.5 simulator available for use in licensing operators
- SimultaneouslyCompare current trending with reference data.Statistical built-in functions to evaluate code performance, such as sensitivity & uncertainty study.Give insight to code users.Simultaneous code performance, do not need to wait until code to be terminated to know how code performs comparing with reference data.
- demo case was applied to both desktop psa-hd & full-scope simulator PSA-HD.Desktop PSA-HD does not include S3R & BOP. Has successfully run the different transient for 32 hours.Full-scope PSA-HD has interfaces built-in and integrated with full-scope simulator. Has successfully run LOCA for more than 8 hours.
