The 2003-2004 activity of Reactor Integral Test WG under Subcommittee on Reactor Constants of Japanese Nuclear Data Committee will be presented. During this period, the WG carried out integral tests of JENDL-3.3, ENDF/B-VI and JEFF 3.0 for reactor applications. Some results of integral tests for other latest libraries, JEFF-3.1, ENDF/B-VII, etc. will be also presented. Nuclear Data Library in D...

The growth in demand of electricity is increasing relentlessly in India. The growth rate of installed electricity generation for the past two decades is found to be above 8 % and is much higher than the growth of any other sector in India. The realization of commercial fusion power reactor will take at least another fifty years. Hence, in the first half of this century, it is expected that the ...

Previous Advanced Fuel Cycle Initiative (AFCI) studies were made to assess the effects of the existing accumulation of LWR spent fuel in the United States on the capability to partition/transmute actinides using existing and advanced LWRs. The concept of treating the “oldest fuel first” indicated that significant advantages could be gained in both partitioning, transmutation, and in overall cos...

JNC has proposed an evolutional concept of fast reactor recycle system for minimising high-level waste (HLW) by adopting an unconventional recycling scheme based on the idea of “rough removal of unnecessary elements” instead of a conventional one as “pure recovery of necessary elements”. The concept was named “ORIENT-cycle” (Optimisation by Removing Impedimental Elements). “Unnecessary elements...

SmFeAsO1−xFx was irradiated in a fission reactor by a fast (E > 0.1 MeV) neutron fluence of 4 × 1021 m−2. The introduced defects increased the normal state resistivity due to a reduction in the mean free path of the charge carriers. This leads to an enhancement of the upper critical field at low temperatures. The critical current density within the grains, Jc, increases upon irradiation. The se...

Testing and evaluating candidate fusion reactor materials in a high-flux, high-energy neutron environment are critical to the success and economic feasibility of a fusion device. The current understanding of materials behavior in fission-like environments and existing fusion facilities is insufficient to ensure the necessary performance of future fusion reactor components. An accelerator-based ...

For several decades, the United States has been without an ongoing program measuring levels of fission products in the body. Strontium-90 (Sr-90) concentrations in 2089 deciduous (baby) teeth, mostly from persons living near nuclear power reactors, reveal that average levels rose 48.5% for persons born in the late 1990s compared to those born in the late 1980s. This trend represents the first s...

iii ACKNOWLEDGEMENTS I would like to thank my parents for providing me with a loving and supportive environment which cultivated my love for science and the drive to pursue it; my advisor, Professor Stacey for his insight, guidance, and reassurance throughout my introduction to the discipline of nuclear engineering; Professor Petrovic who helped refine my understanding of reactor physics; the p...
