Potential Model Changes as a Result of Fukushima
2
FLEX
• Portable diesel generators • Portable pumps – Diesel generator driven – Electrical powered
• Who is setting these up? • Who is operating them? • Who is controlling their operation?
3
Electrical System Upgrades
• New batteries – Additional batteries – Larger batteries
• New chargers – For new batteries – Capability to cross connect
• Portable diesels – Starting and operation – Dynamic effects of starting loads
4
Electrical System Upgrades
• Cross connection capabilities – At the 480 vac bus level – At the DC level – At the instrument bus level – Individual loads – Manual cable installation – Manual transfer switches – Auto transfer switches
5
Electrical System Upgrades
• Granularity of loading – DC busses – Instrument busses – Are “key” individual loads accounted for? – Is everything a lumped load
• Do you have control of the lumped load? • Granularity of configuration
– Do you have the capability to shift all loads onto train ‘A’ so you can save train ‘B’?
6
Electrical System Upgrades
• Granularity of configuration – Can you strip the key non-essential loads? – Is the loading dynamically accounted for on the
instrument busses and ultimately the battery? – Who is stripping these loads?
• Non-licensed operators?
• How are you controlling this from the simulator? – New graphics for in-plant panels
7
Electrical System Upgrades
• Operation at reduced bus voltages – Are loads individually coded for bus voltages? – Or are the busses only true or false?
• Battery dynamics – Large discharge rates – Extended discharge at varying rates
• UV relays – Are they on/off? – Set and reset – Time delays
8
Instrumentation
• Are the instruments powered correctly? – Correct source – Correct failure mode – Recorders – Transmitters – Indicators
9
Communications
• Are the power supplies for your communications in the simulator models? – Paging system – Phone system – Radio system – How long do the UPSs last for these systems?
• How are you charging the radio batteries?
10
Human Elements
• Limited access to site? – Watch turnovers – Additional support – ERO
• Installing FLEX equipment
11
Plant Changes
• Procedure changes – Are they going to affect the level of fidelity
needed in the simulator to support?
• Plant physical changes – What needs to be modeled in the simulator? – How are we going to model the added
flexibility that has not been available in the past?
12
Funding
• Becoming part of the plant modification team
• 2-step approach – Upgrade model now – Add detailed functionality later
• Is funding available now?
13
Local Panel Visualizations
• Diesel panels • Switchgear • DC breaker panels • Other local control panels • FLEX equipment – Pump connections – DG control and connection – Cross-connection installation
