Potential Model Changes as a Result of Fukushima email@example.com
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
