The ability to efficiently and comprehensively evaluate synthetic routes at their earliest stage of development is especially important in pharmaceutical process research and development and chemical engineering laboratories [1 and 2]. The evaluation and optimization of typically complex synthetic sequences (involving many reaction parameters) frequently entails bench-scale experimentation of a...

The neutron energy spectra have been calculated in the fuel region, inner and outer irradiation sites of the zero power research reactor using the MCNP-4C code and the combination of the WIMS-D/4 transport code for generation of group constants and the three-dimensional CITATION diffusion code for core analysis calculations. The neutron energy spectrum has been divided into three regions and co...

This paper analyzes the mechanism of the fast response characteristic of a magnetically controlled reactor and response characteristic of magnetically controlled reactor in semi-limit saturated. A model of fast response is established based on pulse width modulation technology, and the simulation analysis is completed. The simulation results show that the response speed of magnetically controll...

The safe operation of a fast burst reactor (FBR) depends directly on the knowledge, experience, and judgment of the operating staff to understand the mechanisms by which experiments influence the reactor’s behavior. Fast burst reactors are a unique class of research reactors that generate high yield, self-terminated power pulses from reactivity insertions exceeding prompt critical. These reacto...

Recent research has indicated the advantages of combining anaerobic and aerobic processes for the treatment of municipal wastewater, especially for warm-climate countries. Although this configuration is seen as an economical alternative, is has not been investigated in sufficient detail on a worldwide basis. This work presents the results of the monitoring of a pilot-scale plant comprising of a...

The development strategy of nuclear fusion energy in the Korea National Basic Plan for the Development of Fusion Energy consists of several major programs. These are shown in Fig. 1, and include KSTAR for the study of a long-pulse, advanced tokamak operation, ITER for a burning plasma experiment, the DEMO reactor for the demonstration of producing net electricity from a fusion reactor, and a co...

in this research, shielding and criticality safety calculations carried out for interim storage and transportation cask in the tehran research reactor. such dual purpose cask is being designed to the spent fuel elements of research reactors. the monte carlo mcnp5 code calculation was utilized for the criticality safety analysis and origen2.1code was used for shielding calculation. according to ...

Pervaporation membrane reactors are ideal candidates to enhance conversion in reversible reactions generating water as a by-product. This equilibrium displacement can be enhanced through close integration of reaction and separation by way of catalytic membranes. In this research, catalytic hollow fibre pervaporation membranes for the close integration of reaction and separation will be develope...
