EDF Torness: Summary

7

• History of Simulator– Various systems were upgraded by GSE

previously Turbine Supervisory and Electrical Systems

– Was built in 1989 by Marconi– EDF extended the operating life of the plant

by 7 years to 2030 and decided to replace and upgrade the simulator to overcome limitations in computing systems, plant models and control systems

• Objective– Modernize existing simulator built in 1980s– Leverage similarity with Heysham 2 Plant

EDF Torness: Scope

• New computer systems

• Replace all process models, logic and controls using advanced simulator tools

• Simulate Ferranti’s Data Processing Control System (DPCS):– 303 DBT graphic formats– 140 Station Reactor Services (SRS) graphic formats– High fidelity controllers (CC01-CC11)– Alarm system

• Simulate ALSTOM turbine control system

• Simulate fueling machine system

• Provide 5 simulator platforms; Unit 1, Unit 2, Classroom, De-briefing , and Development

• Provide integrated Unit 1 and Unit 2 simulators

• Provide touch screen softpanels

EDF Torness: Technology• JADE suite of simulation tools

• SimExec

• JTOPMERET for thermohydraulic of Advanced Gas-cooled Reactor (AGR)– Successfully implemented in Heysham– Proven technology and cost-effective solution using GSE JADE tools

• REMARK core neutronics

• JStation instructor station
