6. 1. Transportable 2. Sealed Core – Safe and Secure
• Unit will measure approximately 1.5 x 2.5 m • Factory sealed
• Must fit into standard transport container • No in-field refueling
• Modular design for easy and safe transport • Closed fuel cycle
3. Safety 4. Operational Simplicity
• System will handle any accident through a
combination of inherent and engineered • Operation limited to reactivity adjustments to
features maintain constant temperature output
• Inherent negative feedback (with respect to
temperature) keeps the reactor stable and
operating at a constant temperature 6. Isolated Power Production
5. Minimal In-core Components • Electric generation components requiring
maintenance in an accessible location
• Operational reliability is greatly enhanced by • Allows existing generation facilities to be
the reduction of moving mechanical parts retrofitted
• Each unit will generate approximately 70MWt and 25MWe – enough to
power 20,000 average American homes.
• Overnight costs at $2,000 - $3,000 per KW capacity
