Segmented CVD reactor designs enabling spatial control of across-wafer gas phase composition were evaluated for depositing graded films suitable for combinatorial studies. Specifically two reactor designs were constructed and evaluated with experiments and response surface model (RSM) based analysis to quantify the reactor performance in terms of film thickness uniformity, sensitivity to adjust...

The urea reactor is one of the most important units in the urea synthesis process. Rigorous simulation of the urea reactor is necessary and significant. Ho,wever, the complicated thermodynamic system and chemical reactions result in difficulties of modeling and simulation. In this work, the urea reactor is considered as a critical gas-liquid concurrent fluid reactor, in which some perforated pl...

The design of the plasmachemical reactor is described. The reaction zone of the reactor is the plasma generated by injecting the continuous or intermittent electron beam into dense gaseous or vapor media containing dispersed powders of the material to be treated. The tests of the reactor showed the beams of moderate electron energy to be able to create the uniform reaction bulk, the plasma para...

Being equipped with small reactor AIP is the trend of conventional submarine power in 21st century as well as a real power revolution in conventional submarine. Thus, the quantity of small reactor AIP Submarines is on the increase, and its decommissioning and decontamination will also become a significant international issue. However, decommissioning the small reactor AIP submarines is not only...

have sprung to life in these recent years at the welcome sight of a possible nuclear power renaissance, IRIS (International Reactor Innovative and Secure) is the one that has moved most rapidly from an idea to a viable, albeit still at the preliminary design stage, commercial entry. IRIS is a modular pressurized water reactor with an integral configuration (all primary system components—pumps, ...

An important milestone on the Fast Track path to Fusion Power is to demonstrate reliable commercial application of Fusion as soon as possible. Many applications of fusion, other than electricity production, have already been studied in some depth for ITER class facilities. We show that these applications might be usefully realized on a small scale, in a Multi-Functional Compact Tokamak Reactor ...

A new tool for optimal heat transfer design has been constructed by coupling the OPT optimization library to the TACO D nite element heat transfer code The optimization heat transfer code can be used to quickly and e ciently nd optimal operating parameters required for target design criteria This tool has been applied to the heat transfer design of a rotating disk chemical vapor deposition reac...

This project deals with the problem at the core of chemical processes, that of creating a structure for the reaction-separation-recycle system. New methods have been developed for the synthesis of such structures capable of screening a wide range of options and taking account of all of the trade-offs simultaneously. For the first time these methods are capable of fully taking into account the i...

The fusion-fission hybrid system has the potential attractiveness of good safety performances and plenty of fuel compared to the fission reactor system and also easing the requirement of fusion plasma technology. It is a practical path to the early fusion application for energy production. In this paper, a fusion-driven subcritical reactor for energy multiplier, named FDS-EM, is proposed. It ca...
