BREI Conducted Comprehensive Independent
Reviews of Passive Heat Removal Systems with
Ejectors-Condensers
•
Euratom DEEPSSI Project for the design and development of a
passive steam generator emergency feedwater system for
existing and future PWRs using advanced steam injectors
•
Independent Review of the Russian Passive Heat Removal
System with Ejector-Condenser (PAHRSEC) for
Implementation in VVERs and Other Reactor Technologies
•
Evaluation of PAHRSEC in combination with steam-driven
Auxiliary Feedwater Pumps for diversity in decay heat removal
in the event of an extended Station Blackout for new VVER TOI
reactor design.

BREI Developed Numerous Low Cost
Mitigation Strategies for Fukushima Events
• Developed numerous strategies for coping with extended loss of AC
power using existing equipment, manual actions, on-site portable
equipment, pre-staged off-site equipment, and off-site personnel
support including:




Equipment type, design, and quantity
On-site equipment storage and protection from external hazards
Off-site regional equipment storage
Emergency preparedness and procedures/training/staffing
• Designed cost-effective post-Fukushima Spent Fuel Pool Level
Instrumentation System with provisions for missile protection,
seismicity, reliability, independence, power supply, accuracy,
displays, and testing for implementation at operating plants.
