Outline
3
Changes Affecting Training
• Emergency response organization (ERO) staffing changes
• Knowledge, skills and proficiency requirements
• Severe accident management guideline (SAMG) changes
• Extensive damage mitigation guideline (EDMG) changes
4
• Post-9/11 revisions to NUREGs/FEMA REP
• Post-Fukushima initiatives
– NEI 12-01 – Guideline for assessing beyond design basis accident response staffing and communications capabilities
– NEI 12-06 – Diverse and flexible coping strategies (FLEX) implementation guide
– INPO IER 13-10 – Nuclear accident at the Fukushima Daiichi nuclear power station
– US NRC SECY-11-0124 - “Recommended actions to be taken without delay from the near-term task force report”
Change Drivers
5
Challenges for Industry
• Near-term challenges– Develop, write, train and drill on new SAMG/EDMG
processes and procedures– Install, maintain, train and drill on FLEX equipment– Increase in number of staff needing training/drills– Multiple-unit scenarios with single-unit simulators– More challenging PRA/PSA
• Long-term challenges– SBO and beyond DBA scenarios– Limited simulator capabilities– Integrated training of NOP, EOP, SAMG and EDMG
6
GSE Desktop Simulator
• Used by EPRI and ERIN Engineering to demonstrate capability of MAAP5 computer code “Modular Accident Analysis Program”
• Users easily interact with equipment controls and code models through modern human-machine interface
• Interface with plant DOSE model to project offsite DOSE
• Users visually observe the event unfolding via graphical depiction of scenarios
7
GSE Desktop Simulator
• Take plant data and run myriad SAMG/EDMG scenarios
• Simulate parallel events in multiple units
• Provide “what if” analysis of user-interactive actions and resulting consequences
• Provide interactive access to all model internal variables
• Assist with verification/validation of results against plant data
• Collect, assimilate and report a large amount of data

Applications
Can be:– Run as stand-alone machine for individual use– Synched with other desktop simulators– Controlled/managed by an instructor– Used for training as individuals or teams
17
Flexibility and Growth
• Can add additional modules, such as:– Balance of plant– ECCS– Electrical– Main steam– Main feed water– MIDAS, RASCAL
• Advanced 3D visualizations coupled with simulation models can be added to inform the user of conditions inside containment and reactor during severe accident scenarios
• Can integrate with your simulator
18
Conclusions
• Provides cost saving and lessens burden imposed by regulations
• Allows frequent and realistic training
• Uses the most advanced analysis models as daily training tools
• Backed and supported by reputable engineering/simulator teams
• Streamlines data communications
19
Conclusions
• Prepares personnel– Supports operational decision making to support
transient analysis
• Supports development and implementation of challenging and realistic drills
• Does not require plant simulator time
• Supports remote training
