Micro-heterogeneous thorium based fuel concepts for pressurized water reactions
The purpose of this work is to evaluate the potential for enhancing the performance of the once-through PWR fuel cycle by appropriate design of thorium containing fuel with concurrent consideration of neutronics, thermal-hydraulics, and proliferation resistance. CASMO-4 is employed to model a fuel …

The development and characterization of aluminum fueled power systems and a liquid aluminum fuel
Various aluminum-water reactions were thermodynamically analyzed across a wide range of temperatures and pressures to determine the most favorable reaction under each condition. Results show that under most achievable temperatures and pressures the reaction will produce AlOOH, however at low …
