Production of fatty acid esters from stearic, oleic, and palmitic acids and short-chain alcohols (methanol, ethanol, propanol, and butanol) for the production of biodiesel was investigated in this work. A series of montmorillonite-based clays catalysts (KSF, KSF/0, KP10, and K10) were used as acidic catalysts. The influence of the specific surface area and the acidity of the catalysts on the es...

The current resurgence of interest in the nuclear power industry has led to renewed interest in new reactor designs. The GE Compact Modular Boiling Water Reactor (CM-BWR) is one such reactor. The 350 MWe CM-BWR is designed for small incremental additions to the power grid. A key feature of the CM-BWR is the use of the unique F-Lattice. The F-Lattice employs a staggered row configuration for the...

The hybrid Small Modular Boiling Water Reactor (SMBWR) is a new conceptual design of BWR-type SMR. main features SMBWR include natural circulation loop in its coolant recirculation system and external superheaters integrated into the steam cycle. A full core analysis performed with nodal diffusion code PANTHER using homogenised constant libraries generated by WIMS. study compared number geometr...

Monitoring of sensor operation is important for detecting anomalies and reconstructing the correct values of the signals measured. This can be done, for example, with the aid of auto-associative regression models. However, in practical applications difficulties arise because of the need of handling large numbers of signals. To overcome these difficulties, ensembles of reconstruction models can ...

This paper summarizes a study of the implications of a technology-neutral regulation for advanced nuclear power plant designs and proposes a predominately rationalist approach to future nuclear plant regulations. The current body of regulations has been developed and evolved over the past 50 years with consideration of the knowledge and incidents experienced from operation of the Light Water Re...

basic understanding of the process of coolant heat transfer inside an engine is an indispensable prerequisite to devise an infallible cooling strategy. coolant flow and its heat transfer affect the cooling efficiency, thermal load of heated components, and thermal efficiency of a diesel engine. an efficient approach to studying cooling system for diesel engine is a 3d computational fluid dynami...
