Surface Power – PDR John Dankanich (2-13-01) Dispersion Fueled 100 kWe Reactor

Assumed 500 M from Routine Activity System Dimensions Assumed 500 M from Routine Activity

Total Mass is Approximately 3,000 Kg. Mass Breakdown Total Mass is Approximately 3,000 Kg.

Cost Analysis Cost of Complete System: $750 Million • Production • Development • Production • Testing Each additional unit $250 Million • High Cost due to testing

Risk Assessment Radiation: Over 500m Distance for routine crew activity Radiation below acceptable occupational dosage Failure: Single Failure Modes are Difficult to Eliminate History - 3 Nuclear Incidents in 19 US missions Transit-5BN-3, Nimbus, Apollo 13 Snap-10A Reactor Failure Terrestrial Plant 1/17000 Reactor Years

Comparisons Existing Space Power • Heavier, Lower Shielding Terrestrial • Lighter, Smaller, Passive DRM • Lighter, Lower Power Dr. Zubrin • Comparable Mass, Comparable Power

Bottom Line • Cost of $750 Million ($250 Million per additional unit) • Reliability of 0.95 (0.98 after prototype) • Power Output 100 kWe (115 capable) • Lifetime of 5 years (7 max) • Mass of 3 Tonnes • Footprint of 13 m2
