Intergranular stress corrosion cracking &YSCC) is a pervasive and generic problem in current light water reactor and advanced reactor designs that can lead to widespread component failure. IASCC is believed to be due to either to changes in the grain boundary composition, the microstructure or the water chemistry and corrosion potential. Of greatest interest are the changes in composition and m...

Intergranular stress corrosion cracking (IGSCC) of Alloy 132 weld metal in light water reactor (LWR) structural components is a great concern. The microstructure of Alloy 132 is dendritic and the grain boundaries that are parallel to the direction of the dendrites growth are known to be most susceptible to cracking. In order to correlate the grain boundary microstructure to IGSCC, and in genera...

Transmutation of burnup products for a typical VVER-1000 reactor in fusion-fission hybrid has been investigated using MCNPX 2.6.0 calculation code. Burnup fission was performed 1000 MW practical power VVER core UO2 fuel and light water as its coolant moderator, well. The have classified separated according to their half-lives usages, the remaining wastes were used fuels reactor. also implemente...

A new approach is investigated utilizing light guidance capabilities of optical pure quartz glass in order to maximize drinking water disinfection efficiency with UVC-light-emitting diodes (LEDs). Two experimental setups consisting of soda-lime AR® glass (VWR, Darmstadt, Germany) or HSQ® 100 quartz glass (Heraeus, Wasserburg, Germany) reactors were designed to compare disinfection rates with an...

Introduction Research on the conversion of natural gas (methane) has been an ongoing effort at the National Energy Technology Laboratory (NETL) for over 20 years. A long-term goal of our research team is to explore novel pathways for the direct conversion of methane to liquid fuels, chemicals, and intermediates. Scheme 1: Proposed pathway for the photocatalytic conversion of methane and water L...

Abstract Operating conditions in the liquid metal fast reactor, like higher power density, temperature gradient, and burnup, are more severe to fuel rod comparing light water reactor. The integrity safety of is very essential reactor safety. In this study, designed for M 2 LFR-1000, which a typical pool type lead cooled evaluated using performance analysis code named KMC-Fueltra. Irradiation be...

The consumption of petroleum products has been significantly increasing year by year. Petroleum offers a tremendous convenience for our life, and our daily life would be quite different without it. However, the depletion of petroleum is creeping under our foot. Lignocellulosic biomass has unlimited potential because it is possible to substitute for petroleum as energy and chemical sources. Rece...

BACKGROUND Microalgal triacylglycerides (TAGs) are a promising sustainable feedstock for the biofuel, chemical and food industry. However, industrial production of microalgal products for commodity markets is not yet economically viable, largely because of low microalgal productivity. The latter is strictly dependent on initial-biomass-specific (IBS) light availability (i.e. ratio of light impi...
