Molecules are bound very closely in ice and much less rigidly in water; hence water acquires fluidity and follows the law that water finds its own level by flowing from higher to lower levels. The rigid binding of molecules in water is loosened by heating. When we raise the temperature to nearly 100°C, the molecules are so energized that they get the freedom to leave the folds of gravitation an...

The puri®cation of water by heterogeneous photocatalysis is one of the most rapidly growing areas of interest to both research workers and water puri®cation plants. Recent literature has demonstrated on a laboratory scale the potential of this promising technology to completely destroy organic pollutants dissolved or dispersed in water into harmless substances. However, to date no viable pilot ...

abstract the goal of this research is simulating an optimum reactor to eliminate greenhouse gases, mainly co2, through combined cycle in stacks of power plant, using a strong base (sodium hydroxide) thinned by water. during this process sodium bicarbonate salt is generated together with water and the produced salty water is desalinated and its useful salts are also extracted. four scenarios hav...

The core conversion studies of the Ghana Research Reactor Core started in 2006 and with the objective of designing an LEU core with similar operational capabilities as the original HEU core and with acceptable safety margins under both normal and accident conditions. Steadystate studies for converting the Ghana MNSR facility from HEU to LEU core have been performed using the PLTEMP/ANL V4.1 cod...

In commercial nuclear power plants, many containments use stainless steel bellows at piping penetrations, in dry well-to-wetwell vent lines, or as a part of the fuel transfer tube. Bellows are an integral part of the primary contain ment pressure boundary in nuclear power plants. These bellows allow for thermal expansion and contraction of the pipe, vent line, or fuel transfer tube, and accommo...

supercritical water oxidation has attracted attention of many researchers ever since the ideahas emerged about three decades ago as a promising technique in the waste managementindustry. providing more details about the behavior of a supercritical water oxidation systemunder various operating conditions and extending available data can greatly assist more accurateand reliable design of such sys...
