This presentation discusses the tools used for simulation training before and after the Fukushima nuclear event. It also discusses the practicality of these new tools and what next steps should be taken for nuclear training. Visit gses.com and follow GSE Systems on Twitter at @GSESystems

1. Simulation Training Post Fukushima
DesignEP – Beyond Design Basis Standalone Model
info@gses.com

2. 2
The Tools: Past
• Most plant reference simulators are not capable
of beyond design basis (BDB) event.
• Currently, the majority of the beyond design basis
training is done in a classroom using table top
discussions and “what if?” scenarios.
• Almost none of the training is done with a
simulator.

3. 3
The Tools: Future
• Standalone high fidelity engineering grade
severe accident models
• Multiple unit site models
• High level of student interactivity
• Live “what if?” capabilities
• Combining already proven severe accident codes
and proven simulation technology to provide
ultimate learning solution

4. 4
The Technology: Past
• Severe accident training technology was limited
to PowerPoint presentations.
• Maybe a walkthrough or discussion on the plant
reference simulator

5. 5
The Technology: Future
• Proven severe accident codes
– MAAP, MELCOR, etc.
• Integrated with proven simulation technology
• Easy-to-use student interface

6. 6
The Practicality
• Plants already own a severe accident code and
are currently using it for PRA/PSA.
• Standalone and portable
– Does not add additional burden to existing
plant reference simulator
• Can be used to train operators, ERO, TSC
personnel, EOF personnel, etc.

7. 7
The Practicality
• Opens a view into the plant and containment to
see what is happening
• Can be used by engineering to provide additional
functionality to the existing toolset

8. 8
The Next Steps
• Combining multiple severe accident
models into a single severe accident
training system
• Looking at the site level effects of a major
event and the effects on multiple units
• FLEX implementation at a site level

9. 9
Takeaways
• There is a very good chance you already own a
beyond design basis model that can be used to
create a severe accident training system. This will
save you money.
• BDB training can be done without the plant
reference simulator. Most plant reference
simulators are already overburdened.

10. 10
Takeaways
• Severe accident response should consider site
level response and effects.
• Site level simulation is a new concept.
• Our approach to severe accident simulation can
be used across the organization. It is not just a
training tool but can also be used for engineering
and analysis.
• Shared resources = shared costs
