The initiating postulate of energy has hairsplitting the prerequisite of alternative reservoirs of energies other than fossil fuels. At the present time, considering cost factors, environmental viability and unlimited resource of power, nuclear is one of the best options and in this era of energy crisis. In this paper, Characteristic features of gen-4 nuclear reactors, its reactivity control mechanism,...
Nations seek to establish nuclear power within their borders to meet their growing demand for energy. This analysis compares and contrasts the use of the industry standard 1.5 GWe light-water reactor and a smaller 500 MWe CANDU-type reactor in the implementation of nuclear power in relation to material accumulation, fuel cycle process capacity, economics and nonproliferation. The fuel cycle analysis...
In the global framework of nuclear fuel behaviour simulation, the response of the models describing the physical phenomena occurring during the irradiation in reactor is mainly conditioned by the confidence in the calculated temperature of the fuel. Amongst all parameters influencing the temperature calculation in our fuel rod simulation code (METEOR V2), three sources of uncertainty have been identified...
Very compact, ultra lightweight nuclear reactor systems that can be rapidly deployed by existing military transport vehicles are described. They can provide multi- megawatts of continuous electric power at remote locations without needing large scale logistic supply of fuel for conventional diesel-electric generators. Such power systems enable important new military capabilities, including electromagnetic...
Radioisotope cells (RCs) and a direct sodium borohydride/hydrogen peroxide fuel cell ( FC) are compared to conventional chemical batteries through Ragone plots of theoretical (RCs) and experimental (chemical batteries and FC) data. It is found that the RCs are projected to have superior specific energy but inferior specific power, while the borohydride/peroxide FC shows an impressive range for both...
Energy is the bedrock of our daily lives and industry. Now is the time that industry, government and academia must join together and examine highly independent, fully environmentally considerate and rational energy systems. In this presentation, recent Japanese policy will be introduced focusing on new national energy strategy. Looking at future technology trends, it is probable that, in the case...
