A new strategic energy plan decided by the Japanese Cabinet in 2014 strongly supports the steady promotion of nuclear fusion development activities, including the ITER project and the Broader Approach activities from the long-term viewpoint. Atomic Energy Commission (AEC) in Japan formulated the Third Phase Basic Program so as to promote an experimental fusion reactor project. In 2005 AEC has r...

Radiation shielding analysis and development for the Nuclear Cryogenic Propulsion Stage (NCPS) effort is currently in progress and preliminary results have enabled consideration for critical interfaces in the reactor and propulsion stage systems. Early analyses have highlighted a number of engineering constraints, challenges, and possible mitigating solutions. Performance constraints include pe...

The potential for efficient production of hydrogen-rich gas from hydrocarbon fuels using thermal plasmas has been investigated both analytically and experimentally. Thermodynamic analysis shows that the most efficient production of hydrogen from hydrocarbons can be achieved by partial oxidation (lambda = 0.25); at optimal conditions, the availability of the output fuel mixture is 83 percent of ...

In the last decade, Microreactor Technology (MRT) as a new concept in chemical engineering has demonstrated the advantages of microstructured devices for chemical reactions impressively. Microscale reactors are devices whose operations depend on precisely controlled design features with characteristic dimensions from submillimeter to submicrometer. Due to the small amount of chemicals needed an...
