1. Fukushima’s Impact:
Beyond the SAMGs and New Equipment Training

2. Accident Conditions
• Loss of all off-site power sources
• Loss of all on-site power sources, including
diesel generators
• Destruction of communications infrastructure
• Severely limited plant access
2

3. Operator Training Focus Areas
• FLEX equipment
• Long-term loss of electrical power
• Severe accident response
3

4. FLEX Equipment Training
• Training must be developed for new and
modified equipment to address:
– Restoration of electrical power
– Reactor makeup capabilities
– Reactor core cooling
– Spent fuel pool makeup capabilities and cooling
4

5. Restoration of Electrical Power
• On-site/Off-site Equipment
– Portable engine driven generators
– Batteries and chargers
– Personnel must be trained to:
• Locate and transport equipment
• Connect portable equipment to installed
plant components
• Operate, monitor and maintain equipment
5

6. Reactor Makeup
Capabilities and Core Cooling
• On-site/Off-site Equipment
– Portable pumps
• Engine driven or powered from portable generators
– Normal and alternate on-site water sources
• RWST, CST, Rx makeup, fire water, raw water
• Borated water
• Fire trucks and tanker trucks
6

7. Reactor Makeup
Capabilities and Core Cooling
• Personnel must be trained to:
– Locate and transport equipment
– Connect portable equipment to installed plant
components
– Route and connect on-site sources to alternate
connection points via temporary hoses
– Operate, monitor and maintain equipment
– Monitor plant parameters with limited or no electrical
power or lighting
7

8. Spent Fuel Pool
Makeup and Cooling
• On-site/Off-site Equipment
– Portable pumps
• Engine driven or powered from portable generators
– Normal and alternate on-site water sources
• RWST, CST, Rx Makeup, fire water, raw water
• Borated water
• Fire trucks and tanker trucks
8

9. Spent Fuel Pool
Makeup and Cooling
• Personnel must be trained to:
– Locate and transport equipment
– Connect portable equipment to installed plant
components
– Route and connect on-site sources to alternate
connection points via temporary hoses
– Operate, monitor and maintain equipment
– Monitor plant parameters with limited or no electrical
power or lighting

10. Long Term Loss of Electrical Power
• Training must be developed for an
extended loss of all electrical power to
address:
– Shedding of all but the most critical loads from the
instrument buses to prolong battery life
• This may require simulator electrical model upgrades
– Operating with limited lighting, communication
equipment and instrumentation
10

11. Long Term Loss of Electrical Power
• Training must be developed for an
extended loss of all electrical power to
address:
- Coordination of FLEX equipment usage
- Restoration of communication equipment and lighting
in the control room
11

12. Severe Accident Response
• Simulator software has not historically been capable
of modeling beyond design basis/severe accident
scenarios
• Lessons learned from Fukushima illustrate the need to
train the plant staff on severe accident situations,
including revised SAMGs and newly developed
guidelines
• New models will be necessary to run severe accident
scenarios for reactor core, containment, auxiliary
building and spent fuel pool
12

13. Conclusions
•
New training must be developed for:
– FLEX equipment and related procedures
– Evaluating and shedding DC and instrument
bus loads to prolong battery life
– Managing situations with limited or no lighting or
normal communications equipment
13

14. Conclusions
•
New training must be developed for:
– Revised SAMGs and new emerging guidelines
– Emergency response organization interface
