Fuel UO2 (0.5% U-235) Moderator material Graphite Moderator volume fraction 95% Multiplication factor 0.97 Radius (cm); Height (cm) 30;50 Source strength (neutrons/s) 1x1012 Power (kW) 1.2 DOE FF Hybrid WS Gaithersburg MD 9/09 An alternative to the standard driven reactor accelerator-spallation target design is proposed which employs IEC neutron sources which can be in a central location or distributed across a number of fuel channels. Such a modular design has distinct advantages in reduced driver costs, plus added flexibility in optimizing neutron flux profiles in the core. The basic physics for the IEC has been demonstrated in small-scale laboratory experiments, but a scale-up in source strength is required for ultimate power reactors. The IEC source strength is already near the level required for low power research reactors or for student sub-critical laboratory devices. This application would be advantageous since the safety advantages of these reactors should enable a next generation of research reactors to be constructed quickly, meeting the educational and research needs facing us as there is a rebirth of interest in nuclear power.

Armory Ave., Champaign IL 61821 Fusion Ship II, is shown capable of roundtrips to outer planets with times ~ 1 year, the design goal. Development issues include demonstration of a gain of 9:1 or better. Other issues include RD on the Direct Energy Converters, design of power conditioning, high powered density NSTAR thrusters, and lightweight crew shielding. The 14.7 MeV proton flow (28.3 N) could be used if mass is added to increase thrust. Then the energy conversion system could be greatly simplified. This will be studied in Fusion Ship III. * * * * * * In accelerator measurements with the Ti-target at 2.5 Ed 10.0
