  1. 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 Conducted Comprehensive Independent Reviews of Passive Heat Removal Systems with Ejectors-Condensers

  2. Passive Heat Removal System with Ejector-Condenser (PAHRSEC) • Steam Generator 4. Check Valve • Ejector-Condenser 5. Start-up Valve • Heat Exchanger 6. Start-up Tank

  3. 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. BREI Developed Numerous Low Cost Mitigation Strategies for Fukushima Events
